As per the previous Metro games, there is a morality point system which affects the outcome of the game's ending. You get morality points by doing certain things such as playing through areas of the game without killing anyone and freeing innocent prisoners.

There are also three achievements relating to this system; Duke, Damir and Alyosha. You can get these after completing certain areas throughout the story with a good enough moral standing. You will also get an additional achievement for getting all three in one playthrough.

Duke
Duke survives.


You will get this at the end of the mission to lower the bridge in the level VOLGA as long as the criteria is met. Essentially, try to stealth your way through everything. Don't hurt anyone at the church and sneak through to the final scene of the level.

Damir
Damir stays with crew.


You will get this after fighting off Baron's assault at the top of the tower. For this one, you want to make sure none of the innocent slaves are killed in the previous couple areas. Guil and Damir mention it a fair bit as you enter the areas, so keep an ear out.

You can also help to get this by doing things like retrieving Guil's photo when looking for the maps and freeing villagers from a couple areas across the CASPIAN level.

Alyosha
Alyoshga doesn't get wounded.


Same stuff as Duke and Damir, but for the TAIGA level. You'll want to try and get through each area without killing anyone. Note that you cannot even stun enemies if you want to get Child of the Forest. There are also a couple opportunities to free people and get some points.

Also make sure not to kill the weak or innocent as you will block out some positive morality points later on as well as getting immediate negative ones.

Full Strength
Duke and Damir stay with the crew, Alyosha doesn't get wounded.


Do all the above things across a single playthrough and you will be well on your way to get the good ending.

You will get these achievements by simply playing through the main story of the game.

Exodus
Complete the MOSCOW level.


You'll get this one just after detonating the bomb on the enemy train.

Aurora
Name the locomotive.


You actually get this one right near the start of the following level. During the opening cutscene of this level, the train is given a name and you'll get this achievement then.

Regatta
Get into a boat.


Near the start of the next mission, where you need to go to the Church. Anna will lead you to a boat you can use to get there. Jump in and you'll get this.

Fisherman
Kill the Catfish.


While on your way to Krest's railcar, you'l' find yourself in a compound filled with mutant humans. Go through this area to the railcar on the other side. You'll need to drop some debris to free the track.
Lure the catfish in by dropping one of the bodies in the water, then pull the lever to free the railcar and kill the catfish in one fell swoop.

Railwayman
Get into the Trolley.


After dispatching the catfish, you can now enter the railcar to continue with the story.

Long distance passenger
Find the passenger train car.


Shortly after getting the rail car, you will drive it to a bandit camp. After dealing with the bandits, you can use a lever at the top of the building to open up the gate. Once it's open, you can drive the railcar through the gate and connect up the passenger car.

Lower the Bridge
Complete the VOLGA level.


You will get this after lowering the bridge and jumping back onto the Aurora.

Spoiled dinner
Complete the YAMANTAU level.


You'll get this once you find Anna and get on out of there.

Driver
Drive the Bukhanka.


Fairly shortly after getting to the CASPIAN level, you will come across a thug who you can neutralise and take a car key. Go back to the car, and after a short cutscene you'll be able to get into the car and get this achievement.

Complete road map
Find maps in the laboratory.


Not long before the end of the CASPIAN level, Guil will guide you into the laboratory. You will eventually come across an archive with years highlighted at the edge of each shelf. After interacting with the shelf labeled 2019, a short animation will play, then you will unlock this one.

New order
Complete the CASPIAN level.


After confronting "the baron" and defeating his forces, you will get this after a short cutscene.

Gor'ko!
Attend the wedding on the SUMMER level.


Following the CASPIAN level, there will be a wedding on the Aurora for Stepan and Katya. You will get this when you toast to their vows. Man, everything sure is great... right?

Silent marksman
Kill 30 enemies with Tikhar.


The Tikhar is a pressurized steel ball rifle, which you will need to charge up to use.

After rescuing Katya from the church in the level VOLGA, you will return back to the train to continue the story. After talking to Colonel Miller, enter the Aurora and you'll be given a Tikhar which you can find on the left as you enter.

The kills do not need to be stealth kills, and you can kill both mutants and humans to get progress for it.

Firebird
Kill a demon with fire.


For this one I found a demon hanging upside down under a bridge, which made it a very easy target.

I threw one molotov at it, and got the achievement immediately, so they're pretty weak to fire.

Kaleidoscope
Kill 3 enemies using sniper scope while wearing the Gas mask and using the Night Vision goggles.

To get the Night Vision goggles, you can go past the catfish before you get the railcar in VOLGA and enter a room in the back to find the goggles at the other end of the room.

If you saved the villagers near Duke before coming here, they will reward you with a key that lets you open a door at the start of this area. This means you can get the goggle a little earlier.

Once you have them, wear them alongside your gasmask and take out three enemies with a weapon that has a sniper scope equipped. I found that the Night Vision scope I had for my Tikhar counted for this as well.

Righteous vengeance
Kill 90 cannibals.


You will get this during YAMANTAU, after Anna is taken and you break free. There will be swarms of enemies at certain parts, so this will tick up pretty fast.

Carmaheddon
Make 50 kills with the Bukhanka.


During CASPIAN, you will find a car that you can drive around during this level. You can drive through enemies to kill them very easily. At night, there are more mutants around, so it could be worth driving around then.

Antibiotic
Kill 300 mutants.


This will just tick up over time. Mutants include nosalises, watchmen, demons, etc. as well as the human mutants.

Headhunter
Kill 300 human enemies.


This will just tick up over time. Human enemies include bandits and cannibals.

Saboteur
Melee-kill or stun 50 enemies.


This only applies to contextual stealth kills where you can perform either a lethal or non-lethal takedown. If you just melee an enemy to death in-game or during a QTE, then it is not counted.

Professional
Make at least one kill with every ranged weapon.


There are ten ranged weapons that apply for this.
1. Kalash
2. Ashot
3. Revolver
4. Bastard
5. Tikhar
6. Gatling
7. Valve
8. Bulldog
9. Shambler
10. Crossbow

You shouldn't have much trouble finding each of these. Keep in mind you won't get the crossbow until the level TAIGA.

Robin Hood
Kill 30 enemies with Crossbow.


As mentioned above, you won't get the crossbow until the level TAIGA. Once you do, just ensure you use it for a while and rack up the 30 kills.

Gunsmith
Install a modification of each category on a single weapon.


Simples. You can find weapon modifications by getting them from weapons found in the world. Then you can place them on your weapons at a workbench or from your backpack.
Generally, it looks like standard weapons will have the following categories:

• Stock/Grip
  
• Barrel
  
• Sight
  
• Magazine
  
• Gadget

You'll need to equip one from each category to unlock this.

Friend of the Crew
Find the guitar and teddy bear on the VOLGA level.


Before you head out to find Krest's railcar, talk to Nastya and your squadmates regarding their Teddy Bear and a guitar respectively. They will each give you a location to find those items, and there will be special icons on the map for them. Go to each location and retrieve the items.

As the achievement suggests, you only need to find these items, you don't actually need to take them back to the requester. Though... you still should.

Handyman
Spend 500 consumable resources on crafting.


You should get this fairly easily just in your normal playthrough. You can find resources all over the place, just check buildings and bodies of guards. Then you can spend those resources on crafting ammo, throwables, filters, medkits, etc...

Tidyman
Spend 500 chemical resources on cleaning weapons.


This one will take a bit longer than the above. Cleaning weapons does not require as many resources as crafting and can only be done at a fixed workbench. Go splash around in some puddles to muddy up your weapons.

Join us on air
Find a tune on the radio.


You can get this during the short levels that take place on the Aurora, like SPRING and SUMMER. Sit down at the desk in your room and interact with the radio. Cycle through the tuning fairly slowly until you come across a station just playing some music.
This is what I had it set to when I got it.

Last Breath
After running out of filters in a hazard zone, craft a new one while suffocating.


This one isn't too difficult if you're ready for it. If you have a big stockpile of filters, you can dismantle them at a workbench first. Then while in an area where the gas mask is required, wait for the time for you current filter to drop down to zero.
Then you can bring out your backpack and craft yourself a filter. You'll get the achievement as soon as you craft it.

Decommunization
Destroy the biggest statue in front of the children's camp on the TAIGA level.


Not long after starting the TAIGA level, you'll come across this statue.
A single crossbow shot the head of the statue will net you this achievement.

Librarian
Find all 70 hidden Diary pages.


Old world pictures
Find all 21 post cards.


Dressed for Success
Find all upgrades for Artyom's suit.


There are a few of each of these in most chapters. If you look in the collectibles menu, you can see which you've missed in the order they can generally be found.

As for the suit upgrades, there are 12 in total, but no way to see a list of ones you've missed in-game. I will instead list them here and include them in the following walkthrough.

I'll put a walkthrough in the following sections with each collectible's location.

Please keep in mind: While the guide is a WIP, there will be some missing collectibles. ;_;

After coming across your first Nosalises of the game, you'll find a sort of alcove off to the immediate right.
This diary entry is sitting on the desk in this area.

After the first little part of the game, you will wake up in a hospital bed. When you can, move directly forwards and find Artyom's medical file on a desk on the right.

Leave the hospital room you wake up in and head into the next small room, but do not continue through the following door. Instead, look to the right and see the postcard on a locker.

Wait a week. From the start of this area, follow Anna down the first set of stairs.
Instead of continuing down the stairs, go down the corridor and enter the room with the open door on the right.
In this room you'll find the postcard next to the window on the far side of the room.

From the room mentioned above that had the postcard in it, head through the doorway on the left into the neighbouring room. You'll see a letter on a small box in this room.

Coming soon...?

Coming soon...?

After getting shot in the face dog tag, you'll soon crawl through a small opening and pick up some medical supplies.
Look straight ahead when exiting this opening and you'll find the next diary entry, near a buried skeleton.

Continue on until you reach the room with the communications jammer and you can find this entry on the console behind the angry dude.

After leaving the angry dude and making your way across the following courtyard, you'll enter a tight corridor leading to the next area.
In this corridor you'll find this diary on the workbench in the corner opposite from where you entered.

This diary is on the enemy train right near the end of the level. After boarding the other train, you'll take out an enemy as you enter the train through a window.
As soon as you get in, you can go through an opening on the right and enter the next room.
This room has a couple guards, but you should be able to grab the diary from the desk without alerting the guards.

Coming soon...?

When you can, go past Anna and head down the stairs.
At the bottom of the stairs is the diary entry on the left-hand side.

After leaving the church, you'll meet up with Duke. He'll let you know about a nearby plane.
Head over there and go inside. At the front of the plane you'll find the radar suit upgrade.

From the plane, start heading back towards the Aurora.
On the way, you'll come across a couple skewered shrimps.
In a small camp behind them, you can find this diary on a bedroll.

After falling down the hole and finding Anna, start going through the level.
You'll come across a grate with a padlock. Break it and enter the room.
At the end of the room on the far side you'll find the next entry.

When you're going to meet Krest at the port, look nearby for a staircase going down on the ground level.
Head down and fight off an ambush of mutant humans.
Go across from where you entered and look on a shelf directly opposite you.

Coming soon...?

Coming soon...?

On your way to get Krest's railcar, meet up with Duke at his lookout. He will drop down and let you know about a few points of interest. The one you should head for is the gas station.
After clearing out the bandits, enter the room on the left at the front.
You can find the diary on a table in this room.

Coming soon...?

When you wake up in the passenger train and leave the room Anna's in, swing a right towards where Nastya is.
Not far down the hall, look in an alcove to the right.
The diary is sitting on a table here.

When you get off the elevator that rotates around the outside of the silo, you'll be in front of this doorway.
Head through and look on the left side.
The diary is on a desk here.

While searching for Anna, you'll come across this room where there is a switchbox you can interact with behind a shelf on the right.
Interacting with it will light up the area behind it.
Crawl past it to get to this diary entry.

Shortly after, you will hear Miller talking about where the team should rendezvous.
In this area, stick to the right and climb over some boxes.
Afterwards, go into an office on the right side and find the diary on a low box.

Eventually you will fight a heavily armoured guy with a gatling gun.
Following that, you will enter a corridor with a few enemies.
Enter the open door on the right to find this diary.

Reunited with Anna, you will go toward an elevator.
Before entering, look to the left.
This one is sitting on a barrel just there.

Coming soon...?

One of the roads will go under a building with an entrance on one side. There will be a slave standing at the door.
Enter here and continue to the back and find some stairs to head upstairs.
On the next floor, walk around to the back of the stairs entrance to find this diary on a bench there.

Continue on in the same area until you come across some thugs.
You will eventually come across a ladder and there will be a radio on a table nearby.
This diary entry is on the table with the radio.

Right near the last diary is a ladder. Head up there and go straight ahead through this door.
Go right and look for a desk.
The upgrade will be on that desk.

While on your way to meet Guil, you'll pass through a cave with some Thugs in it.
Part way through, some will mention smoking and will cause an explosion.
As you enter this area, hug the left wall to find this letter near the edge here.

The next few entries are in the spider labyrinth when you're looking for the maps.
Shortly after entering the labyrinth, you'll have to turn some lights on in an office kind of area. Stick to the left on your way to the next area and look in a small cubicle.
The diary is on a desk in here.

After hearing an update from Damir, you'll enter another room with a hole in the wall opposite.
In the back right corner, there is a desk with someone slumped in a chair at a desk.
The diary can be found on this desk.

Shortly after, you'll come across a conference room with a large table and many chairs.
Check the head of the table closest to the wall of monitors.
The diary is on the table at this end of the table.

Talking to Anna, she'll tell you about a few things in the area, one being a shipwreck where prisoners are held. There are quite a few thugs in here.
There's a large room with a few walkways that you'll go from end to the other. On the end you want to go towards, check the room on the ground floor on the right. (Doorway in the very bottom-right of the above screenshot)
The helmet will be on a small shelf in this little room.

Another tip from Anna will be a traffic control tower that you might want to check out.
Head over there and play through to get to the top.
In the top room you can find the NVD Amp on one of the spinny chairs. I forgot to take a screenshot before picking it up ;_; but it will be on one of the chairs here.

Near the road toward the north of the map, there's a sloped path down to the left where you can find The Baron.
To the right of The Baron is a cave entrance.
Head in there and you can find this upgrade at the back of this cave.

Coming soon...?

You might come across this junkyard with a bus hanging up above the road.
Climb up on the left side of this area (based on screenshot) to a walkway.
The diary is on a box here.

When you're sneaking into the water area with Damir, you'll drop down a ledge and Damir will comment that you can't turn back.
Almost immediately you will walk under a metal structure. Turn to the left and you'll see ramps on this structure you can walk right up.
At the top, you'll find the diary on a radio up here.

When asked to follow your friends to the wedding upon leading your room, instead go right toward the back of the Aurora. You can do it after the wedding, but it takes a while for it to finish.
You'll go on a train car outside, then go back inside in the following car.
Swing a sharp right and find this diary on the workbench in this area.

Right near the start of this mission you'll get the crossbow.
Immediately look to the right and enter the shed on the right-most side.
This postcard is on a wall in there.

Going left from where you got the crossbow, you'll come across this gate.
Once you get closer, you'll hear the sound of a crossbow bolt hitting.
Check the left door of the gate to find a message attached to a crossbow bolt.

Not long after you'll get to a school with a statue out front.
Once in this area, check the first building on the right.
This entry is on a desk close the entrance.

Coming soon...?

You will climb to the top of a tower as part of the story.
You should hear a radio transmission when you get there.
The diary is sitting on a box next to the zipline to the next area.

In the following area, stick to the left side.
This place is prety lit up so it should be easy to see.
Get past the guy here and find the diary on his bed.

Coming soon...?

As you continue on, hug the left wall.
You'll eventually come across this small cave.
The diary is sitting on a desk at the back of the cave.

At some point you'll come across a guy who is friendly if you holster your weapon.
Go into this nearby house.
The diary is next to a fireplace on the right.

Once you've entered the larger compound with a bunch of enemies, have a look near the right side on the ground floor.
There's a room in this area where two people are talking about food being cooked.
The diary is on the table on the left side of this room.

After leaving the village you'll see this fire in a cave tunnel.
This letter is on a small box next to the fire.

Shortly afterwards, you'll be walking through a dark narrow tunnel.
Someone above will drop a body down into this tunnel.
A little further along this tunnel will be this diary entry on the floor.

Leaving the caves, you'll be overlooking a small village.
On the right side of this area is a decent-sized house.
Go in and enter a larger room near the center.
The postcard is on a wall next to a doorway.
