As a fan of Creeper world 1 and Creeper world 2, i was really happy when Creeper world 3 came out. Even more happy i was when i found it on steam. I bought it immediately without hestitation and when this guide was started, I already had 75% of achievements yet only a single week have passed.
Yet the game is not that easy and people were asking from time to time how to do this or that. I decided to write an achievement guide because little information is avalible about achievements now.
I hope you will find what you need. If not, feel free to ask me personally.

Now, if you are for achievement which requires something on any map, you can actually create your own map to do that. This helps if you cannot find suitable map.

Note: some categories may see too empty. This is because there is a limit of 8000 characters per sections so i had to split categories.

These achievements will be completed while you progress on story missions. They are teoretically missable, but if you build every new building you find, you will get these without realising.

These achievements are unlocked when you destroy an enemy structure with nullifier or other means. If you play through main story, you will automatically get them. They are teoretically missable, but if you use new building you find, you will get all of them without notification.

First Emitter
Destroy first Emitter
The emitter is a structure which produces creeper continiously. It can be destroyed with a nullifier. It is present in almost any mission, so the first mission you can destroy it is Tempus on Inceptus system. Simply follow tutorial instructions, expand your network, protect it with pulse cannons and build a nullifier when in reach of emitter.

Simply follow tutorial instructions, expand your network, protect it with pulse cannons and build a nullifier when in reach of inhibitor. You do not need to destroy other structures - destroying inhibitor immediately destroy every creeper structure on the map.

First Spore Tower

First Runner Nest
Destroy first Runner Nest
The runner nest is a structure which produces runners. First mission you can destroy it is Defi on Egos system. Build your regular defense and offense, then build snipers to destroy runners and proceed to the nest, moving sniper to continue protection. Destroy it with a nullifier when in range. Every runner will die when all nest are destroyed, unconnected nest will destroy runners spawned by them.

First Air Exclusion Tower
Destroy first Air Exclusion Tower
The air exclusion tower is a building which block aircrafts from entering area it protects. You will first meet one at Crosslaw in Frykt system. On this map, you should move to the tower from upper left corner. Proceed as usually. Tower range here is quite small, so you still can use aircrafts to get to other emitters. Tower can be destroyed with a nullifier.

These achievements require you to BUILD required building some amount of times in a SINGLE mission. Game does not requires you to have such amount of building at once, so you can build a building and destroy it afterward. Note that building process must be finished - simply placing will not count.

It is highly recommended to try those achievements when you have big conquered territory and you are one step away from win. You can save your game and reload it for different achievements. Also make sure that you either dont overbuild or if you do it does not hurt your defense.

It is also recommended to have forge with 10/10 build speed upgrade and 10/10 energy efficiency upgrade.

Dont forget also that you can drag your mouse after holding left mouse button to build a line of buildings. This way it will require much less precise clicking.

Building that were on the map from the beginning don't count. Only the ones you have manually built.

Pulse Cannon Lover
Build 50 Pulse Cannons in a mission.
Should come naturally as in some missions one of the best way of proceeding is pulse cannon assault. Otherwise, you can use them anyway to defend.

Relay Lover
Build 100 Relays in a mission
Relays are long range connectors and speed up packets between them. Until you get destroyed a lot, this one will not come naturally.

Mortar Lover
Build 50 Mortars in a mission
Will probably not come naturally. After building so much, you can send them in some deep creeper to kill 90% of it in a short time.

Shield Lover
Build 25 Shields in a mission
May come naturally on Choix in Egos system. Remember shields take a lot of energy, so if you are going to boost it, destroy them or turn them off if you dont actually need them.

Terp Lover
Build 25 Terps in a mission
May come naturally on different missions if you like terraform fast and a lot. Otherwise, they are not much expensive and take no energy after built.

Nullifier Lover
Build 20 Nullifiers in a mission
You can get this in Arca in Cricket system as towers and emitters respawn thanks to creeper Nexus. You can get it in any other mission by destroying your nullifiers after they have been build but before they destroy an enemy.

Collector Lover
Build 300 Collectors in a mission
Collectors are very cheap so you can go for this achievement in any mission. It is unlikely however that you will receive this naturally as 300 collectors will be overlapping too much.

Whoops!
Build 2 Forges in a mission
As achievement picture suggests, in order to build second forge you NEED to destroy your first forge or let it be destroyed by creeper.

Reactor Lover
Build 200 Reactors in a mission
Building oh so many reactors will give you really big amount of energy. Yet it will probably have to be boosted because 50 reactors is usually more than enough for any mission.

Strafer Lover
Build 50 Strafers in a mission
Nothing much to say here other than that strafers can be used after building on emitters to severely minimize amount of creeper they produce.

Beam Lover
Build 50 Beams in a mission
I highly doubt that someone can get it without boosting because you need no more than 10 in a mission. However, in Unknown scenario, part 2 in Link327 system in Alpha sector you probably need not just 50, but even more.

Guppy Lover
Build 20 Guppies in a mission
I got this naturally when i was sending Guppies into creeper to charge totems to get aether in Otrav in Andere system. If they are destroyed by creeper and start automatically rebuild, it still counts. They are quite cheap and you only need 20 so this on shouldn't give you any problems.

Bertha Lover
Build 25 Berthas in a mission
Unless you really love them, you will be boosting this. I recommend Otrav from Andere system as there is plenty of space and a mission is not hard at all.

Ore Mine Lover
Build 15 Ore Mines in a mission
I haven't found a mission with 15 ore deposits so you will have to build and destroy and then rebuild. I tried my own map but it did not worked by some reason.

Bomber Lover
Build 50 Bombers in a mission
Best done on map with ore because you can use 50 full bombers to totally annihilate creeper even in very deep parts and also temporary prevent it from spreading.

Sniper Lover
Build 40 Snipers in a mission
You don't need many snipers to clear out runners so you will have to boost. After that, I can't suggest a good use for them other than sending them into creeper and watch they die.

Sprayer Lover
Build 50 Sprayers in a mission
Best done on map with ore because you can use 40 full sprayers to totally slow creeper severely by sending sprayers into creeper and turning Always ON option on. Will work with creeper moderately deep.

Thor Lover
Build 5 Thors in a mission
Best done in Arca in Cricket system. You will have to build some Thors to win anyway. I built 4 and simply reloaded before winnning when i discovered this achievement. There are not much other missions where Thor is avaliable anyway.

Siphon Lover
Build 20 Siphons in a mission
I have not seen a mission with 20 resouce pack at once, so you need to build, destroy and build again. Ormox in Navox mission have 5 energy packs so i suggest this mission.

These are achievements which are cumulative and require you to build some building certain amount of times in all your playthroughs. They all should popup eventually. Best you can do to speed them up is to build a lot of those buildings when you are about to finish a mission. Not too boring, not too slow, not too fast.
These achievements are updated when you complete a mission. If you want them really quickly, you can build huge amount of building you want, save right before you win, win, reload, win, repeat until achievement unlocked. Especially helpful for collector master. Note that it may stop updating info on steam achievement page, but when you enter and exit a game, it will show proper amount of buildings built.

Reactor Master
Build 5000 Reactors total
Naturally this one may come in 200-300 missions but if you like to be sure that your systems are always well powered, you may receive it much earlier.

Bertha Master
Build 200 Berthas total
May come quickly if you like this weapon. May take a lot of time if you don't. As it's only 200 of buildings i recommend boosting it if you really need it out of order.

Terp Master
Build 500 Terps total
I personally like to build tons of terps for quick terraforming. Yet i don't terraform in every mission. But given the fact that there are lots of missions where there are small annoying holes and bumps, you will probably get this in 100-500 missions, depending on how much terps you will be building.

Relay Master
Build 5000 Relays total
Will take a lot of time as relays are used mainly for otherwise unconnectable areas and for packets speeding, yet only ten or so are required for a mission. Yet I recomend you to get it in the habit to optimise your network with relays before each attack. You will get it much faster that way without much boring boosting.

Sprayer Master
Build 600 Sprayers total
This is not big amount but you will usually not have more than 3-5 sprayers per map, depending on how much ore you can get per second. It would require about 200 missions if you use them frequently.

Beam Master
Build 1000 Beams total
Will surely come in not that big time because if you have spores in a mission, you WILL have to build those and in quite good quantities.

Sniper Master
Build 600 Snipers total
Will take quite long time as runners don't appear that often and you rarely need much snipers per mission.

Forge Master
Build 400 Forges total
You mostly can only have one forge per mission and you will probably build it in quite safe place. Not every mission allows forges or have totems, so it will require quite big amount of missions to make this naturally. Making your own map is an option, but you can only set forge build limit to 0 or 1. To make it go faster, you can build, destroy, build, destroy and so on, then save righjt before winning, then win and reload. The game will remember that you have built many forges when it saves.

Thor Master
Build 100 Thors total
Now this is unusual one. There are only oh so rare missions where Thor is avaliable and you will rarely have much because of limits. You either have to be lucky or use custom map.

Bomber Master
Build 750 Bombers total
Not that hard. When you will be using bombers, good chances that ore production may be not much high. So you will probably be building lots of bombers, charging them and sending them into creeper all at once. Yet it would require about 100 of such missions and not every mission have ore.

Guppy Master
Build 500 Guppies total
In my opinion, guppies are extremely useful. I almost always use at least one in a mission, more if doing assault in hard to reach areas.

Mortar Master
Build 2500 Mortars total
Mortars are important for your survival. You will probably have around 5 in each mission depending on difficulty. This one surely should be done as one of last achievements.

Strafer Master
Build 1000 Strafers total
Strafers can be described as flying pulse cannons. I persoanlly use them in missions with digitalis to cut it from emitters. Such way i need not to worry about runners. If you will do something similar, you will get it in about 50-100 digitalis missions.

Nullifier Master
Build 750 Nullifiers total
Those are ones which you will be guaranted to build. They are just vital in finishing missions. Will take about 150 missions to get naturally.

Siphon Master
Build 800 Siphons total
This is probably one of the hardest. Only some missions (i can count about 5 of all i played) have resources, collectable by siphon. And you need 800. This is ridicilous achievement in my opinion. Surely will require boosting.

Ore Mine Master
Build 1000 Ore Mines total
If you like anticreeper, this one should not take too long. It would require about 200-400 missions with ore to get this naturally.

Collector Master
Build 10000 Collectors total
Collectors are your main energy source early game so you will surely be progressing toward this achievement steadly. This one requires biggest amount of all in this category.

Shield Master
Build 400 Shields total
Shields are quite useful, especially if you pair them with sprayers. Dense creeper requies qiute a lot of shields to push it back. Should require about 60 missions of shield using.

Pulse Cannon Master
Build 2500 Pulse Cannons total
As with Mortar master, this will also be one of steadiest achievements as blasters are oh so good at defending. Will require about 150 missions.

These achievement require you to kill certain type of enemy in a mission some amount of times. You need to find a mission where you have enough of such enemy. Or you can create your own mission with required amount of enemy.

Runner Assassin
Destroy 500 Runners in a mission
Any mission with runners will do. Start such mission prepare you defense and build snipers so that they as much close to runner nests as possible. They will start making kills. To speed this up, push creeper back enough so that snipers can shoot runners as soon as they spawn. May take 10 or so minutes depending on how often runners spawn and how much nests are there.

Runner Nest Assassin
Destroy 10 Runner Nests in a mission
I have not seen yet a mission with so much nests so i completed this one by manually creating a map with 10 nests and a nillifier on power zone so that it takes just 2 seconds to finish the mission. Notify me if you know what mission naturally contains so much nests.

Emitter Assassin
Destroy 20 Emitters in a mission
I personally got this one in Arca in Cricket system. Nexus in its first phase spawns spore towers and emitters. Keep destryoing them and this one will popup.

Spore Tower Assassin
Destroy 20 Spore Towers in a mission
I personally got this one in Arca in Cricket system. Nexus in its first phase spawns spore towers and emitters. Keep destryoing them and this one will popup.

Air Exclusion Tower Assassin
Destroy 8 Air Exclusion Towers in a mission
No main campaign mission contains so much towers. I made this one in Gatekeeper in Link327 system in Alpha sector. Map is not hard. Just push slowly and you are good.

These are achievement which require you to kill certain amount of certain type of enemy over all your missions. These can be boosted by creating your own map with required type of enemy. Note that in map editor you can place unlimited amount of enemies (or buildings) into a single space and place finished nullifier in range for easier achieving.

Runner Ender
Destroy 5000 Runners total
This one is easiest of this type. Simply start eny map with runners, place snipers in range of nest and go drink a tea or something. Don't forget to put speed to 4x.

Nihilist
Destroyed 20 Inhibitors in Tormented Space
There isn't much of advice here. You cannot keep destroying the same inhibitor - it wont count if it has been destoyed once. So you must destroy inhibitors in 20 different systems.

Uninhibited Nihilist
Destroyed 50 Inhibitors in Tormented Space
Same as Nihilist but you need 50 inhibitors.

Air Exclusion Tower Ender
Destroy 150 Air Exclusion Towers total
If you like to use aircrafts, you will probably achieve this one a little faster. But there are only some maps containing those towers. Custom maps are recommended.

Inhibitor Ender
Destroy 100 Inhibitors total
This one is slow as there is only one inhibitor per system. Try tormented space or prospector zone - they have planets with inhibitors opened from beginning.

Emitter Ender
Destroy 1000 Emitters total
This is most steady one to get as on each planet you usually encounter 3 to 6 of those in average.

Spore Tower Ender
Destroy 500 Spore Towers total
This one is not much slow too as you encounter spore tower pretty often too and you are also able to destroy them in first few minutes sometimes too.

Runner Nest Ender
Destroy 200 Runner Nests total
Not all maps contain digitalis and not all maps with digitalis contain nests, but you only need 200 and maps with nests usually have more than 1.

These achievements are unlocked when you enter certain sector of the game. Those sectors are unlocked by playing though main campaign of the game.

Training Wheels
Completed Tempus Story Mission
This achievement is unlocked when you complete your first mission, Tempus in Inceptus system. SImply follow tutorial instructions.

Warp Ready
Completed Starsync Story Mission
This achievement is unlocked when you complete Starsync in Abitus system. Mission is not hard. Simply expand your network until you have good energy production, build pulse cannons and sprayers near points where creeper can flow (it cannot flow into space, only on ground), and slowly proceed to inhibitor, destroying emitters on your way.

Junior Officer
Completed Tiplex Story Mission
This achievement is unlocked when you complete Tiplex in Navox system. Mission is quite hard. To win, you should collect command node tech, which will allow you to have 2 command nodes at once. Position them at left and right border and start preparing a defense. Don't forget about spore attacks! When situation is stable, start preparing an offense. Digitalis cannot be taken easily, but with about 10 pulse cannons, you should prevent its regrowth. Blue digitalis, even if there is no creeper beneath, will destroy your buildings, so you need to hold digitalis for nullifier. If amount of creeper is too high, take upper and lower emitters first. When unnecessary emitters are destroyed, proceed to warp inhibitor.

Master Commander
Completed Chanson Story Mission
This achievement is unlocked when you complete Chanson in Egos system. Mission is moderately hard. First, land in left lower corner and start building. Prepare some defenses and build up energy production. Runners in this mission have an ability to destroy your building when in range. You can kill them with snipers which have bigger range than runners. Also, don't forget about spores. I would start destroying emitters and nests from left upper cornerthen you gain access to Bertha. It will help destroying creeper at right lower corner. Finally, when nests are gone, taking right upper corner would not be hard especially because creeper is trapped here.

MacGyver
Completed Vapen Story Mission
This achievement is unlocked when you complete Vapen in Frykt system. Mission is not much hard. First, get some energy collection and build some pulse cannons for defense. When wall breaks, make sure that defense is stable. Build some reactors, but don't overbuild. Then build a forge and connect to totems. Keep defending and upgrade your weapons. With 5/5 weapon range and fire rate, it will be easy to push creeper back. If it is not working, build Bertha, save at least 1000 aether, then fire singularity weapon in the middle of the map or on one of emitters. Then keep firing your Bertha in that stop until singularity wears off. You need to kill enough creeper so that blocky structures are untouched by it. When done, huge beam will fire to the right making it quite easy to go to inhibitor.

Box Art Mission Master
Completed Krig Story Mission
This achievement is unlocked when you complete Krig in Cliff system. Mission is quite hard. First, you need to settle on left upper island because creeper fills lower one too fast. Build your defense, dont forget about spores and build some cannons and snipers around digitalis so it cannot get into island. When you are in a stable position, hard part begins. There may be different approaches, but what i did was building many strafers which i sent along right and lowest digitalis lines. They cut it off completely, so creeper was in space. Make sure you are ready to this. To land on the island itself, i recommend 12 guppies and 30-60 cannons. Settle them on left part of an island and work your way to emitters. Note that if you properly send strafers and they cut off digitalis, runners will not be able to get to you. Then proceed as usual. Your guppies will do a wonderful job.

Peak of Good Living
Completed Meso Story Mission
This achievement is unlocked when you complete Krig in Cliff system. Mission is hard to begin, easy to finish. You have 3 pyramids on the map left upper one produces some creeper and also HUGE shield. Upper middle right one produces a lot more creeper, but smaller shield. Lowest one generates some droids that seek deepest creeper and explode with a lot of anticreeper.
Start above middle tower. Connect to it, then make enough energy so it can work without energy starvation. Then produce 20 more energy and connect to left tower. Then use any weapons to slowly push creeper back. Anticreeper will do most of the job as you will be able to destroy emitter near middle pyramid without building weapons at all. Use Bertha - each shot in creeper will make anticreeper proceed further. Destroy inhibitor to win.

Better Late Than Never
Completed Farbor Story Mission
This achievement is unlocked when you complete Farbor in Andere system. Mission is very hard.
You do not lose if ship is finished! If you don't make it in time, ship will start moving onto corrupted totem. You then gain ability to nullify corrupted totem. If ship moves onto it, then final countdown starts. You have about 35 minutes total to finish the mission.
To finish it, send 2 nodes to upper left island with single emitter and one to lower right island. Destroy emittes here and upgrade weapons in forge. Then build a relay on upper middle island with single ore deposit. Then another one to tiny island beneath. Next, build some guppies and tons of pulse cannons - i used 55. Then this army such way so that guppies can land - beware of air exclusion tower. When area is less or more clear of creeper, build relays and start moving to corrupted totem. Forget about lower left islands. When you are getting close to digitalis, use lots of snipers to kill runners. Move directly to totem, forget about runner nest. Clear out emitters only. If you are doing it fast, you may clear more emitters and spore towers. Finally, build a nullifier near totem to destroy it. This finishes mission.

These achievements are related to last Arca story mission.

Dudley DoRight
Choose Skars in Arca Story Mission
In Arca mission in Cricket system you need allow Nexus to be built. Then there will be some dialogue and you will be presented a choice. Choose Skars Abraxis and you get this achievement immediately.

Happily Ever Before
Completed Arca Story Mission as Skars
This one is very hard. First, land all your command nodes to the right. Then build a circle of collectors around center, outside of creeper pool. Do not destroy 6 laser emitters. When Nexus will appear, you will soon be presented a choice. Choose Abraxis side. Nexus will begin spawning spore towers and emitters.What you need to do isclear creeper in lower right area. Thor will soon land here. You will need to collect Thor tech from there. When you do it, start building them. But build few reactors first. Also, emitters will be placed that way, so creeper will flow outside of ring. Use terps to prevent it from leaking too far away. I allowed creeper to fill left part of the screen, not caring about collectors. Build reactors to compensate the loss. You will need at most 4 Thors to finish the mission. Soon, Aliana will show you location of buried silos. You need to use terps to uncover them. Dig those spaces to depth of 1 and connect them to your network. They will start shooting at Nexus. If you are not planning to uncover them all, you dont need much THors, 1-2 will do the job. Make sure you keep Thors connected to your network - they use a lot of energy, but they dont produce it themselves unlike in the first part of the game. When shield is down, click any THor and click Fire main weapons button. This will fire strong rockets. They may aim creeper, so you may need to clear it out first, but if you will stay close to Nexus, they should aim it.Mission is completed when Nexus is destroyed.

Rotten Apple
Choose Loki in Arca Story Mission
In Arca mission in Cricket system you need allow Nexus to be built. Then there will be some dialogue and you will be presented a choice. Choose Loki imperator and you get this achievement immediately.

The Dark Lord
Completed Arca Story Mission as Loki
This one is much easier than its Abraxis counterpart. Do nothing and wait till Nexus is built. Then choose Loki side. You will then be in control of a Nexus. You can move it with WASD. You can fire its projectiles with left mouse button. Your goal is to destroy 6 shield generators and then building in the middle while avoiding rockets that rocket launchers shoot at you. Enemy buildings regenerate! To destroy one hold left mouse button on it and dodge rockets while Nexus shoots creeper at it. When middle building is down, you have won.

Surgical Strike
Completed Arca Story Mission Early
This one is a close call. Don't unpause the game until you have ordered everything. Place one node a bit above than the middle and to the left of ring. Other two nodes into right empty space. Then make a ring of collectors. Put ONE pusle cannon near upper right, lower right and upper left structures so that you can move them on creeper when they are finished. Place shield near other 3 structures as close to walls as possible. Then, finally unpause. As soon as cannons finish building, move them into creeper. they should lose 90% of health but then push creeper back. Immediately put nullifier there. When shields finish, put nullifier near remaining structures. Here is a screenshot of what you need to do:

These are achievement which are awarded by winning the mission in a special way. Some require some mission, other can be done anywhere. This is divided in 2 parts due to character limit.

Focused
Win a mission by destroying only the inhibitor
You are requied to finish a mission by destroying an inhibitor and nothing else (except creeper). Best way to do this is on Carcere mission in Inceptus system. You dont even need to kill creeper here.
In that mission, land your base in upper left corner, collect relay tech and quickly build to inhibitor. If fast enough, you will be able to build nullifier without destroying any creeper at all.
Here is a video:
Can't Touch This
Complete a non-tutorial story map without creeper damaging any unit
This requies you to complete STORY map, which is located in Arc Eternal sector.
It also requies you to complete non-tutorial map. Tutorial map contains hints in the beginning of round. First system where you can do this achievement is Navox.
In my opinion, best map for this is Flick in Navox system. There is one isolated island where no creeper can be present. Bombers are the key.
Strategy:
1) Land on rightmost island and build some collectors. Then build reactors until your energy collection is around 10.
2) Connect to bomber tech. Then build ore mines. Connect to upper islands with no creeper and build ore mines here too.
3) Build about 10 bombers and wait while they charge. The build a mortar such way so it can bomb island to the left of your. It will decrease amount of creeper quickly. Also build a relay that way so it can connect to that island if you would build relay there. You may need to use terp to raise island border.
4) Send your fully charged bombers when you have anticreeper storage at full capacity to the island on which creeper is being attacked by your mortar. They will quickly turn the isnald into anticreeper island. When no more creeper is present and there is anticreeper at least 5 units deep, build a relay, build 4 pulse cannons and build a sprayer. With cannon you will decrease amount of anticreeper used to kill creeper. Make sure they are not to close to pseudo emitter!! Single tick of damage will ruin achievement. Then using a terp, make a 5x5 hole with depth of one with the center on pseudo emitter. Put a sprayer on that island with Always on option turned on. If done properly, amount of anticreeper should no decrease overally.
5) Build 5 strafers and send them on emitter island so that they shoot from upper part to lower part. This will decrease amount of creeper there.Build a relay to connect to siland in future and build a mortar to help strafers and put it on the edge of freshly taken island.
6)Wait until creeper is no more decreasing and send your bombers. Then build a relay or two whenthere is anticreeper all over the island. so that you can build a nullifier. When it is done, clear shield key island out of creeper with bombers and strafers and collect the key. If you have not been damaged at all, achievement will pop on mission completition.
Here is a screenshot of a finished battle:

Turtler
Take more than 120 minutes to win a mission
Good chance that you will get it normally. I have received it halfway through main campaign. If you dont have it, run any mission, get to the moment when you are one step away from winning, then set 4x speed and wait until mission time is over 2 hours. Then win a mission and it will unlock. You need to win, not to lose.

Patton Would Be Proud
Completed Farbor Story Mission Early
Tough achievement. You need to complete the mission before creeper ship finishes building. I personally made this one when ship was 80 percent complete.
1) Land all your nodes near lower right spore tower and ore processor. Immediately start building nullifier that way so it would destroy both tower and processor. Also immediately start building pulse cannon near the nullifier. It will not be built fast enough.
2) After your nullifier finished, relocate 2 nodes to the left upper island and one to lower right. Do your best to destroy emitters there. Your best bet is to have 4 pulse cannons and one mortar.
3.1) When upper island is clear, built a sniper on power zone - this will significally slow down ore processors as snipers will shoot 2-3 ore ships.
3.2) When lower island is clear build Bertha on power zone and build Forge here too. Make sure you don't have energy deficit. We are doing it here because we are going to connect to mainland through upper island so we dont suddenly lose our upgrades even on a second because we dont have enough energy to power it. Plus such Bertha position will make triple shot to kill creeper horizontally which will make creeper fill a hole much faster, allowing to faster creeper killing.
4) While playing, keep buying upgrades in forge.
Avoid ore and anticreeper upgrade (i made this achievement using pulse cannon assault, but people say that sprayers work good too so you may try anticreeper too. You will want to spray anticreeper on upper part of left part of central island and land your offense/network here), energy storage and avoid move upgrade - it is useful, but you better buy other upgrades.
5) Use relays to connect with 2 small islands to the right of upper island. Make sure that relay on smallest island is built that way so you can connect another relay on main island. Build as much pulse cannon on upper island as you can. Aim bertha a little bit above and to left of center of creeper building.
6) After Bertha shoots 1-2 times, save game and time moving cannons that way so they arrive just after Bertha shot. Move them in group, but move one or two blasters from north shore to build a relay here. If it fails, you did not built enough cannons. Load the game before you made that move. You dont need to cover upper island entirely in cannons to succeed in assault, 20 should do the job and hold their position when you connect them.
7) When you have built relay, progress to upper left ore processor as much as possible. Make Bertha shoot at it. Destroy it with a nullifier.
7.5) While you proceed to processor, build 3-4 snipers not far from battle area.
8) If you are 6-15% away from lose, build bunch of snipers or move existing ones, and put one on power zone which was left after left upper spore tower. This should win you as much as thrice more time if you will be destroying them at least each second time they fly by.
9) Destroy any of 2 remaining processors. Don't panic if you are close to lose. If you have built a sniper and it is not enough, move another one on power zone left from emitter (you should have destroyed it along with nullifier)
10) If you start building last nullifier when it's at 97%, you are probably safe, especially if you have a sniper. Spend aether on build speed to sqeeze some seconds.

These are achievement which are awarded by winning the mission in a special way. Some require some mission, other can be done anywhere. This is divided in 2 parts due to character limit.

Not gonna Vapen
Complete Arc Eternal:Frykt:Vapen without activating the field beam
Field beam is a weapon which activates when all 3 blocky structures are free of creeper.
1) Start mission normally. Deploy defense, build a forge, start producing aether.
2) Upgrade everything you can to maximum. Anticreeper is unnecessary.
3) Stop spending aether on unlimited upgrades when they are about level 5. You will need lots of it later. Then proceed and destroy lower emitter.
4) Now comes difference between normal playthrough and this achievement: instead of going to any other emitters, proceed in lower part of map until you are near tiny point where inhibitor's creeper flows into main area.
5) When you have at least 4000 aether, fire singularity weapon at 100% into inhibitor. Use your best to settle on lower left part of rightmost part of the level.
6) Singularity weapon will slowly turn creeper into anticreeper, destroying both anticreeper and creeper around, slowly decreasing amount of creeper. When possible, build nullifier and destroy inhibitor.
7) Quickly collect artifact, before your defenses uncovered upper blocky structure. Mission complete.

No Fly
Complete Arc Eternal:Navox:Flick without using Bombers or Strafers
This achievement does not differs that much from normal playthrough. My advice is to replace flying units with sprayers and put mortar on the edge so that they can shoot next island (use terps to flatten edges). I myself simply used an army of pulse cannons.

Apexian
Win Arc Eternal:Apex:Meso building no weapons other than nullifiers
You are allowed to use only building from structure tab, forge and a nullifier. In order to complete this you need first connect to 2 upper pyramids and activate their powers - this is allowed as you don't build anything destructive yourself. Then destroy emitter below central pyramid - it should emit enough anticreeper so that emitter will be in reach of nullifier. Then goes hard part: you need to bring your energy production around 40 and build lost of shields. Push creeper with shields so you can destroy right upper emitter. I used 2 columns of 6 shields each. Repeat with other emitters. You can try to go to inhibitor, by i suggest uncovering left lower pyramid - it helps greatly. It does not emits any anticreeper by itself so i don't recommend to take this one in beginning. With this one, it should be easy to destroy inhibitor.
I personally did not used a forge but it would not hurn to have one. Make sure you don't use its singularity weapon. Player nomca wrote that he got the achievement while using singularity weapon. This is a really powerful thing, especially if you use it on emitters after getting lots of aether.
You can also build guppies and supply lower left pyramid with them, this would help a lot, but this may be a bit hard due to high energy consumption.
Also, you can use terps to build zones 3x3 of height 10 near emitters if your nullifiers get destroyed when you try to build them.

Area Denial
Complete Arc Eternal:Egos:Chanson without the destruction of a Glider or a Glider Factory
Pretty uneasy achievement. Not only YOUR buildings cannot kill gliders, but gliders ALSO must not kill your buildings - they die in the proccess and void achievement.
1) Start by expanding your collector network so you gain some energy. Then build some cannons along ravines so that they stop creeper. Finally, build beams to stop spores.
2) We are not allowed to use snipers here. You should also make sure that your building are STAYING AWAY from glider range too. As told before, gliders die if they kill your building and they void achievement that way. As such, I ignored aether resource pack. Yet build a forge and connect to totems. Also make sure that mortar and any long range weapons do NOT have gliders in range because they can kill them too.
3) Build reactors. You will need about 60 energy production for this mission. But don't build too much - we will need space later.
(optional) 3.5) Work your way to upper and middle emitters and destroy them. This will make it easier to defend.
4) Now comes the hardest part. We don't have singularity weapon yet, amount of ore depostions is really low and you will not do much damage with strafers. We also cannot connect yet to inhibitor island. So first, build 10 guppies. Then build a lot of cannons. 50 should be enough, expect 30 of those to die. Then: build 10 mortars, send them above inhibitor, build another 10, send them, repeat about 5-15 times so we decrease depth of creper.
4.5) Make sure you have all maximal upgrades and enough energy for guppy recharging.
5) Send all cannons into are left of inhibitor. Make sure to stay away from gliders! When cannons are about to land, make some gaps and send guppies here.
6) You will lose half your cannons and some guppies. When guppies are away, you will lose more. Then again and again, but as you destroy a lot of creeper, it should slow down. When situation is more stable, build a nullifier and kill an inhibitor. If things are not getting stable, build some lasers on mainland and send them to battlefield.
7) When inhibitor dies, everything dies too. This includes gliders. Such glider destruction does not void achievement. Yet, mission is not over yet - you need to collect artifact. And you can only do this by connecting it to your base. So use any means to clear creeper and collect artifact. This will finish the mission.

Positronic Brain
Completed Alpha Sector:virgilw:Brain Mission in under 60 seconds
Nothing much to say here other than that you should use keyboard as it is faster. Otherwise, practise, practise, practise. No real advice can be given here.
You can use macro program here, but it kills all the fun. This achievement is pretty much achievable. I got time of 50 seconds on my fourth try.

Gunslinger
Win a Prospector Zone mission with only Pulse Cannons and Nullifier weapons
Not as hard as it sounds but requires good map. I suggest S100_111 : Coson. Build your base in upper left corner. Build cannons as soon as possible as upper middle emitter is too close to high grounds. Yet if you will build 2 cannons, then rest of mission should be easy. Just make sure you don't accidentially build other weapons.

Fire in the Hole
Win a Prospector Zone mission with only Mortars and Nullifier weapons
Not as hard as it sounds but requires good map. I suggest S100_111 : Coson, same one as for gunslinger. Build your base in upper left corner. Build mortars as soon as possible as upper middle emitter is too close to high grounds. Yet if you will build 4-6 mortars in first few minutes, then rest of mission should be easy. Just make sure you don't accidentially build other weapons.

Size Matters
Completed Metroid in Alpha Sector:MadMag system
This one is hard to start, easy to finish. There are new enemies and the map is really big.
Here is the order of actions that i have followed on my playthrough. These are not strict, i will just use them to describe how to take on different map parts.
1) First thing first: we need to expand collector network. Build about 10 collectors while covering as much ground as you can. Then you have to build at least some beams. 3 should be enough but i built 5 so that in case of total energy deficit, more energy would come into beams although beams themselves are quite expensive at this moment. When you have anti spore defense, time to care about ground danger. 2 cannons should be enough for some time, but mortar is a good choice too. After that concentrate on building reactors 1 by 1 until you finally climb out of power shortage (if you were into one). Then build forge and connect to 2 totems. This will increase power usage critically at this moment, so spend first aether on energy efficiency.
If you totally lack energy, build sprayer instead of cannons but make sure to defend ore mine. It will cost some to build but it will not use any energy at all.
You can land additional nodes when you start, but i personally filled that space with reactors. Each node vies around 1.5 production which is equivalent to 1 collector and 3.25 reactors. Replacing them with reactors later is a good way to start.
2) When you have some upgrades and energy is no more problem, it is time to take on our first emitters. Put few mortars on edges of your island so that creeper is in range and they should relieve some pressure from other emitters, Then use cannons and blasters to get close to emitters and use nullifier.
Now, it is a good idea to start collecting ore and increase ore efficiency. We NEED anticreeper for one enemy here, although it may be possible to use tons of cannons, but it is a painful way.
3)We will now proceed to our first painful enemy - i don't know what is its name, but jellyfish is what i call this. This thing can:
1. Move on same elevation
2. Lay digitalis in 3 tile space it occupies
3. Spawn runners
4. Spawn laughable amount of creeper - oh come on, why does it spawns creeper at all then?
The problem is that i can't tell you where will it go. It seems to move randomly. Your goal here is to proceed to jellyfish as close as you can, have an army of digitalis prioritied cannons, 6-7 snipers and some patience. This enemy can be destroyed with a nullifier but it can be hard to do so because it is moving. Thankfully, you can place nullifier while jellyfish is in range and it will be finished even if it moves away. BUT nullifying is going to happen only if it stays in range for whole process of destryoing. If it moves away, nullifier stops and need to be recharged. The trick here is to have enough snipers to destroy all runners as they spawn so they don't jam any buildings and build nullifier extremely close to jellyfish. It may move away, then you should build another one close. Eventually, you will destroy it.
4)Next useful step is to proceed to lower left new structure. Don't worry, it is friendly. Getting there is easy too. When you connect to it, it will start charging. It will then act like a huge shield AND will spawn units from time to time. These units fly and they carry lots of anticreeper. They seek deep creeper. They either explode on their target if it still has creeper or when creeper destroys it.
Now it is a good time to free unnecessary power zones and build some Berthas here. They will help in assaulting. If you don't want to use them, build them anyway and put them in autofire mode. If you will in future have idling power zones, build berhtas there too.
5) Next step i did was proceeding on mainland close to our initial position. I started to use anticreeper pretty heavily there. Our goal here is to get to emitter that sends creeper though tiny bridge and cap it with 4 blasters. We cannot destroy it yet.
6) This step is similar to step 3 except that terrain is less favorable and that jellyfish moves faster. It also may be swapped with step 7 if jellyfish is on the right side of the mountain. There is a laser which shoots creeper at your building, so use anicreeper to protect them. This is uneasy to do, so it may be preferable to wait until jellyfish moves right and proceed with step 7 first. Clever thing here is to put 2 sprayers onto anticreeper island with AC collection field turned to on. This will use anticreeper on island as an ammo and help a bit. It will also distract creeper shooter a bit.
7) This is creeper shooter. It shoots creeper at your closest building OR powerzone (must be sort of CRPL Core known bug). Best way here is to maximize ore efficiency and use sprayers as creeper cannon targets. Put to Always on, they can protect themselves and push creeper back. Move sprayers until you can put nullifier in range of creeper cannon BEHIND sprayers. This will eliminate creeper cannon. Jellyfish may interrupt you, use a lot of snipers to counteract or proceed with step 6 first.
After steps 6 and 7 are done, destroy emitters on digitalis to disable it and prevent runners from spawning at all.
Another strategy is to bomb that shooter with berthas, then make territory more safe with bombers and then move some cannons near shooter and guppies behind them. Cannons will distract shooter and will quickly eliminate any creeper it produces making it easier. Thanks Zlia for the tip!
8) Eliminate runner nest to totally make sure that no runners can spawn. After this step, rest of map is pretty easy. It would be also wise to not use collectors as connectors because map is big and lags even on gaming rigs. You need no more than 100 energy production. Destroy unnecessary buildings if perfomance impact is too big.
9) Occupy upper island with help of sprayers.
10) Proceed to island to left of that one and finally eliminate that unreachable from mainland emitter.
11) Go for left upper island now and kill spore tower to make spores less of a problem.
12) Occupy central island and go chaos there - a lot of power zones are ideal for mortars, they will be damaging creeper quite hardly - of course only if you have maximized range.
13) Good time to take second spore tower in right middle part of map. Few beams on power zones will then be able to deal with last tower.
14) Sprayers will be able to take right lower mainland part, if you maximized efficiency and built ore mire on each ore deposit you can. 5 sprayers are enough. You can of course use cannons and mortars too.
15) Proceed to last spore tower and eliminate it. Yaaay, no more beams needed! Destroy all your beams to get some perfomance boost if you have some lags.
16) Finish with right lower part by eliminating remaining emitters. If you want to do it fast, this is good moment to use converion bomb, freeze bomb and a guppy or two. Good moment to eliminate any remaining emitters in upper and middle parts too.
17) Proceed with middle castle. You can go from south east, but sprayers will do the job from north west easy and fast.
18) Finally, do any way of getting onto lower island and eliminate final emitters. You will win the mission. Note that anticreeper emitter does not need to be killed even that it is blue)

Fine Wine
Completed both missions in Alpha Sector:Grauniad system
1) Aigues-Mortes
This one is quite easy, just make sure you don't waste any time in beginning.
Defend phase: You can start either on right middle hill or in upper right corner. I used hill. When you land, build 10-15 collectors. Then build ore mine, sprayer and a sniper. Then build 3 groups of 3 cannons when you have avaliable energy. Set priority to digitalis. Then use each group on 3 branches of digitalis - lower, middle and middle upper. Make your way into middle space in mountain and settle a sprayer here and your middle defending group. Build 2 more sprayers and 2 more snipers and add them into middle. THAT should be more than enough to hold creeper there. Then expand your network so that it cover right mountain side and build mortars that way so they prevent creeper overflow. When this is done, you are safe from creeper. If you have not connected to any totems and have not built a forge, then it is a good moment to do so. If you lack energy, build reactors, but i personally have not built a single one. Build ore mines on avaliable deposits. I personally left sprayers in middle, but you can use them to actually attack.
Attack phase: if you have not noticed already, there is an inhibitor and a lot of enemies. So inhibitor is our target. Proceeding to it is easy. If you cannot take higher ground on your way left, use terp to create some same elevation space as one you are having trouble setting onto. Mortars are quite useful here. Don't forget that you can set cannons to attack digitalis first - this is extremely useful for cannon if you are going to put it on power zone. If you are having troubles with keeping nullifier intact in building phase, create 10 meters (or whatever units they use) high and build a nullifier there. Note that such pillar may be an obstacle for cannons.
2) Waternaris
Special thanks to Mike Mefisto for help with this map.
Extremely tough start here - quick creeper flood and total lack of space. It will probably take about 10 tries to create stable defense here. SAVE OFTEN!!!
OK, lets start:
1. Send a command node into lower left cornet so that it have building space from all directions.
2. Spread collector network so that it covers as much territory as possible - even small spaces will count. Bring energy production to about 2.5
3. Build 2 reactors close to command node and below or to the left of it.
4. Build a cannon on a ridge to the right of command node.
5. Build another reactor.
6. Build a cannon on small hill in low part of the map.
7. Build another one between 2 existing.
8. Build 2 more reactors.
9. Build mortar above command node.
10. Build mortar close to lower cannon.
11. Build reactors until you haven 8+ energy production.
12. Build a mortar to the right of command node.
13. Buildn few more cannons around your perimeter and alos add some mortars.
14. Build more reactors until you have more energy production than cunsumption.
15. Build more weapons until they overally consume 14 energy.
16. If you made it to this point, you are less or more stable. You can at some point lose some territory, but this should not be critical.
Now, build a terp and make some more building space and build few more reactors.
17. Build a Bertha cannon. At this point some of you cannons/mortars may barely be holding creeper. Use Bertha to relieve the pressure in such points.
18. Build a forge. We will use it later.
19. Use blasters and terps to proceed to totems. This should not be hard now. Use Bertha if you are having troubles.
20. When you make it to totems, upgrade your energy efficiency by two. This will give you lots of energy. The upgrade weapon rate FIRST, weapon range second. Doing otherwise may make mortars shoot so far so blasters may fail to hold creeper.
21. Keep upgrading. Weapon upgrades at level 3 should be enough.
22. With such upgrades and weapons, it is now not hard to proceed to inhibitor. Use terp to get some ground. It is just a matter of time till you get there. Use cannons to allow terps to raise terrain, use mortars to actually kill creeper.
23. Runners may interfere, but i have only used a sniper to defend totems. Build a nullifier and wait till it is charged.
24. Congratulations, you have completed probably hardest mission in Alpha sector!
It is hard to describe proper order as mission is really tight. Here are screenshots of my personal progress through the mission (special thanks to Mike Mefisto for collectors positions):

These are all other mission completion achievements that do not fit into other categories.

Varro Hale Award
Win 50 Missions
Creeper world 3 is a great game so i don't think you will be boosting this. If you want however, here is a quick but a bit boring way: create new map and add an emitter with amount of creeper - 0 and start delay 10000. Put a nullifier here. Press Finalize map and a new map will be created. Then enter that map and wait till it is finished. Amount of completed missions will grow by 1. Then enter editor again and change map slightly - add new building, change landscape or so. Then finalize it again (changing will reset best score). Then play it agai and again you will receive one more completed mission. Do it until achievement pops up.
Still I highly recommend you to simply play the game.

Aliana Abraxis Award
Win 100 Missions
Same as Varro Hale award but you need 100 missions.

Dax Joven Award
Win 250 Missions
Same as Varro Hale award but you need 250 missions.

Brainiac
Completed Alpha Sector:virgilw:Brain Mission
This mission is located in first system you visit in alpha sector. To complete this mission, you need to light all 8 things. To ligth one, you need to click it or press corresponding key on keyboard. Those bulbs can only change their state when bulb directly left to them are ON and every other bulb to the left of them is OFF.
1) Press 1 to light first bulb.
2) Press 2 to light second bulb.
3) To ligh bulb 3, you need to turn bulb 1 off first.
4) To ligh bulb 4, you need to turn bulb 1 and 2 off and bulb 3 on.
5) Continue light bulbs until you finally manage to light bulb 8. Bulb 7 will be in ON state too. After that work towards lighting bulbs 6 and 5, then 4 and 3 then, finally, 2 and 1.

Machine Lover
Completed 100 DMD Missions
This will take some time. Fastest and easiest way is to generate very small and easy maps. But it is quite boring so i suggest to try some popular maps or crazy combinations.

These are achievements which are related to collecting energy, ore and anticreeper.

Strategic Reserve
Store 1500 energy
Can only be done on a level where you can build forge and get a lot of aether. Otrav in Andere system is possible choice as there are plenty of totems and also three command nodes avaliable. Build a forge and keep uprgrading Energy storage until you have 1500 energy.

Rainy Day Reserve
Store 2500 AC
Can only be done on a level where you can build forge and get a lot of aether. Otrav in Andere system is possible choice as there are plenty of totems, three command nodes avaliable and also ore deposits not far away from beginning. Build a forge and keep uprgrading anticreeper storage until you have 2500 anticreeper space. Then start upgrading ore efficiency if storage is filling slowly.

Industrial Nightmare
Get energy production up to 2000
Achievment name says it all. This requies really big map. And good PC - even on my gaming rig, i had bad FPS when i finally got the achievement.
I recommend making custom map: make it 256x256. Then add resource pack with 10000 aether. Place forge somewhere. You will need energy efficiency upgrades and build speed upgrades. Also, energy storage is requied to properly use more than 100 energy. Here is a screenshot:

A tip from Saturas: you can add power zones to greatly boost your reactors. Especially useful for weaker PCs.

Forty-Niner
Collected 100 AoO in Prospector Zone
In missions in prospector zone you will find artifacts with letters on them. These are AoO. They can be used for various effects from orbital tab. Freeze artifact freezes creeper in some radius for 45 or so seconds. Mass destroys all creeper in its radius and leaves huge hole. Convert converts all creeper in its raduis into anticreeper. You need to collect 100 of these. Artifacts which were once collected will not count if you restart the mission. You also need to collect them only in prospector zone - custom maps will not count. Note that they count when you take them. This means that you don't need to finish map. You can just land your command node right near the artifact, put a collector, so it connects and wait till it charges and collects. You will still need to clear inhibitors in order to unlock enough maps. Also, if you want to take an artifact from a mission right at the start, but the area gets flooded too quick, the CN won't connect to the artifact without a collector, but creeper will prevent building. You can however land a CN in a safe spot, build a guppy and send it to the artifact - a guppy will survive long enough to charge 15 energy into the artifact, so you will need 2 guppies that way.

Dr. Jones
Collected 500 AoO in Prospector Zone
Same as forty-niner bout you need whole 500. This will take quite a lot of time.

Wrath of the Gods
Fire more than twenty Artifacts of Odin in a mission
I haven't found such mission yet, but easiest way would be simply create your own map, place 20 AoO, emitter in such way so it does not disturbs you and finalize the map, then just start this map, collect those artifacts and fire them.

These are achievemets which are related to command nodes.

Mobility Award
Move a Command Node
After sending down your command node from orbit, you can reposition it like any weapon - select it and move your cursor until it shows new position in green color and then click. Achievement will be awarded when node lands on the ground.

Upwardly Mobile
Move a Command Node 10 times in a mission
Repeat what you have done in Mobility award 10 times. Note: command node must LAND to count for achievement.

Vagrant
Move a Command Node 50 times in a mission
Same as Upwardly mobile, but requies 50 moves.

Ejection Seat
Command Node recalled to orbit due to damage
This achievement is awarded when one of your command node's health is depleted to zero and a node returns to orbit then. Simply land node near the creeper (or into it) and wait.

Rain Man
Rain Anti-Creeper from orbit
You need to return command node to orbit while it have some anticreeper in its storage. Simply find any mission with ore, build ore mines, wait for anticreeper to be produced and launch node into orbit. It also works if it is launched because of damage. Mistet from Frykt system is a good mission to do the achievement.

These achievements are related to Fortress of Ultimate Darkness mission in (only one) Adventure system in Credits sector. This mission is totally different from others: you control some character with WASD or arrows. It can shoot pulse cannon's projectiles. Left mouse button to shoot, right click to toggle autoshoot. Press space when close to emitter (circle will appear when close enough) to deploy nullifier which takes 5 seconds to charge. It is immediately destroyed by creeper. Click on a door to open it when you are close. Colored doors require keys. Collect treasures to increase your score.

MadMag's Mansion
Picked up key from MadMag's room
Simple one: collect key in upper right room. You will have to collect other keys before you can open doors leading to this room.

G-Man
Released AC in Credits Mission
This one is simple too: touch man in lower right room. Attention: not only anticreeper will be released, but a lot of creeper will appear in hallways leading to that room. Again, you will first have to collect some keys to get to that room.

Shhhh!
Find all hidden areas in the Credits Mission
There are 2 hidden areas in credits mission. You need to pugh through the wall to uncover them. One is located below "Charlie was here" text, another one to the left in a room left of entrance. Here are screenshots:
And another one:

These are achievements that do not fit in other categories.

R.I.P
Destroy a built unit on purpose
Most of your units can be destroyed manually. Command center cannot be destroyed. In order to destroy a unit, click it and select Destroy in left lower corner of a control panel.

Hawking Achievement
Fire the Singularity weapon
You can get this achievement only on maps with unlocked forge and totems. First mission where you can get this is Mistet in Frykt system. You need to build a forge here, connect to a totem and get at least 100 of Aether. Fire button will the unlock in forge interface with a slider which tells how much of aether should be used. The more aether the longer singularity will attract creeper. Simply fire this weapon with any strength and achievement will unlock.

Unlimited Potential
Download a Colonial Space Map
This is easy achievement. Enter colonial space from main menu. Then click details on any of maps. Finally click download.

Nip in the Bud
Destroy a spore tower before it finishes building in Arc Eternal:Egos:Ruine
This one easier than it sounds. Send a command node on middle island then quickly build relays to island with an artifact. Then build a nullifier there. Tower should die at about 75%.
Here is a screenshot:


Many Machines on Ix
Max all techs (10 on unlimited techs)
First achievable on Mistet in Frykt system. You need to build a forge, start making aether and upgrade everything to maximum, except energy storage, anticreeper storage and packet speed, which need to be upgraded to 10th level only. Has a good chance of popping up naturally.

Failure Has Its Own Reward
Lose Farbor Story Mission
Easy one. You need to wait about 35 minutes till creeper ship moves onto totem and fully charge it in Farbor mission in Andere system. 4x speed is your friend.

Architect
Finalized a Map
Enter projects from a main menu, click create. Click edit map in lower part of your screen. Then click Create finalized map and agree with popped dialog. DING! Achievement is your.

Critic
Rate a Colonial Space Map
After downloading any map as described in Unlimited potential achievement, play it a bit and then return to map details. Down there will be Rate map line with 10 marks and not rated (NR) one. Click the one you think is approriate for this map and click submit.

Born Leader
Score in the top 10 on a mission with at least 20 scores.
This one requies tons of luck finding map with realistically beatable times. Here are few ways:
1) If you have macro program, you can create a macro that will complete brain mission in alpha sector with required time. NOTE: if you are going to do this, for the sake of community, please make your time just slightly better than the one on 10th position. Let others do this one too!
2) Method above will probably work only for some time because when i discovered this mission it was already partly covered in unrealistic zero second times. There are pure cheaters. For same reason (cheaters i mean), it is really hard to find mission with beatable times. What you can do is to create some mission manually, find 20 friends, share this one with them, let them post thier time and then beat mission yourself, scoring to get 10th or less place.
3) Give a try to DMD zone. You will eventually get lucky and find a zone with not much times, and first 10 scores will probably be less or more beatable. Do your best to complete them quickly.
4) Check colonial space maps. They appear same for everyone. Find such map which have just a bit more than 20 scores and try to finish it quickly.
5) Mix of 3) and 4) Post some map and hope that 20 people will beat it. When creating a map, you can use programming language. Try to program some secret which only you would knew about which allows quick win. Quite unfair way, but i would call this pretty unfair achievemet - the more times pass, the harder achievement is.

Unlimited Possibilities
Name a DMD Map
To name a DMD map you need to complete it. You can name it in score submitting window. Simply generate easy map (small size, single emitter or spore tower), complete it, name it and you are done.

Self Improvement
Improve score or time on an already played mission in Tormented Space
The easiest way to complete this achievement is to start a map which you have not won yet, then proceed up to building nullifier, then save your game, disable nullifier, wait a minute on 4x speed and enable nullifier. Then submit a score, load your last save and don't disable nullifier this time. You will improve your time a little but that is enough for an achievement.
