Capped
Collect all animus data fragments.


There are a total of 100 animus data fragments spread throughout the world. Once you obtain 50 of them, the last 50 will all appear on the map. Pressing <LS> while you run around makes it easy to spot them, and it will put them on your map if you see them while in this mode. Once you go out of eagle vision that is when they will show up on the map (not during).



Sage

The achievement requires that you buy every book shop to have every available book for sale. So you must buy all books from the main map, then 4 from the map you get in Sequence 7. To have all books available, you must have all 15 shops renovated. You also must do all 7 book quests. As you progress through the story, you will be told what they are and they will start appearing on your map. They look like book store symbols except that they have a black border around them.
TOTAL COST OF BOOKS: 453,104.

For most of these combat achievements there is a perfect place to do them all, i will show the place in the screenshot below



I Can See You
Kill 5 guards while under the cover of a smoke screen bomb.


To make the bomb, you must have ingredients to create it. Any shell works technically, but impact is best. Use the British Gunpowder to ensure widest area of effect. The main ingredient to even make the bomb is Phosphorus. You can press to see through the smoke after throwing it. This achievement only requires you to kill 5 enemies in total. You do not have to do it all at once, but you might end up doing that anyways while going for "Lightning Strikes" achievement.

Lightning Strikes
Kill 5 guards in 5 seconds using only your hidden blades.


It is best to combine this with a Smoke Bomb. You must select your hidden blades and cannot use any other weapon. You have to do this extremely quickly. Killing 2 guards at once will be required. You must kill 2, kill another 2, then kill the last 1. Almost all guards travel in 4, so you must find an area with more or lead them with cherry bombs. Throw a smoke down and start assassinating.

Monster's Dance
Have a guard incapacitate 3 civilians while he's poisoned.


Go into a crowded area, poison a guard with a dart, then throw money at him (not the bomb). This will cause people to rush him and you won't be detected as a threat by other guards.

https://youtu.be/cVJ4EQFNrlU

Mosh Pit
Have 10 guards poisoned at the same time.


Focus on crafting both a Cherry Bomb and a Datura Bomb (the poison bomb's name). Find an area with a lot of guards and throw a Cherry Bomb in the center. You may also use other forms of distraction based bombs as well. Of course, there are other ways but the ones listed will make it easier.

https://youtu.be/qrSwuhfAOeI

Mouse Trap
Kill 5 guards with a scaffold after they have been stunned by caltrops.


In order to gain this achievement you must first have a caltrop bomb. When they explode, they have spikes fly out and the guards that walk on them will hop up and down on one foot in pain. After obtaining the bombs, go ahead and look for a scaffold. Get the attention of a group of guards and bring them to the scaffold. Quick throw the bomb, and the guards will walk on the spikes and start hopping up and down. Now run by the scaffold and press <B> to pull it down.

https://youtu.be/7G5kWTYq3xM

Overkiller
Assassinate 50 guards with the hidden blade.


The hidden blade is your main weapon. You press <X> to assassinate an enemy whom is unaware of you. If you kill them in one hit and they aren't attacking you, that's basically an assassination. This will come easily over time as you play the game naturally.

Silent But Deadly
Kill 3 guards simultaneously using only throwing knives.


You want to find guards that don't have any armor on or very little (that way they die in one hit). All 3 guards have to die in one hit. Go to an area with at least 3 of the above guards and make sure you have knives equipped. Hold down <Y> when you have them equipped and you should see the guards light up. Now let go to kill them.

Fond Memories
Achieve 100% Synchronization in all Sequences


Each sequence has a percentage you must fill. This achievement requires you to obtain 100% on every sequence. Each memory counts for the percentage. Some memories are simple and do not have any extra objective that can be missed. There are certain memories that will require you to do something special (an extra objective). This can vary on what is it, and when you start a memory it is detailed for you. You can replay memories by pressing and going to DNA.

A Friend Indeed
Complete all Faction Creed Challenges from a single faction.


There are 4 different factions. Assassin Guild, Mercenaries Guild, Romanies Guild, and Thieves Guild. The one you will want to focus on is Assassin Guild. This is because you have to do most of it anyways and they are the easiest of them all to complete. There are 3 sets of challenges only containing 7 total challenges to do.

Almost Flying
Parachute directly from the top of the Galata Tower to the Golden Horn.


The Galata Tower is the huge tower next to the Assassins' HQ. You can fast travel there using the Tunnel Entrances scattered around. If you don't have a parachute already, purchase some from any tailor. Climb to the top of the Galata Tower and face South (based on map). The golden horn is basically the water that separates the two bodies of land on the map. This is where the ferries are. Just jump and hold <X>, heading south. You will slowly glide to the water. Once you drop in, the achievement will unlock. https://youtu.be/qgBpzyubrhc

Armchair General
Control all cities (Den Defense) in the Mediterranean Defense game mode.


The way you rank up your assassins is through gaining experience mostly through something called Mediterranean Defense. Any assassin den or the assassin boards next to the bomb crafting tables in the cities have the access point for managing assassins. It is also in the Assassin HQ. There are 13 different city names, each with various tasks. The main task you will need to complete in each is "Reclaim The City". This means it is under Templar control and you must send assassins to take it over.

Bully
Find and beat up Duccio.


The character Duccio will be introduced in Sequence 4 Memory 3. He will run off after you confront him. Afterwards, he will remain in the Constantine District. Once you spot him, there will be a red icon on the map. https://youtu.be/xwUYDbeezJA

Craft Maniac
Craft 30 bombs.


During Sequence 3 Memory 4, you will learn how to craft bombs. Once you learn where to go to craft bombs, you can get this achievement whenever you want. While in the bomb inventory during crafting, just pick any of the pouches and fill in the shell, gunpowder, and effect. Then hit craft bomb at the bottom. That will count as 1. Now hit and dismantle the bomb. It will give you back your supplies. Do this over and over again, building bombs and then dismantle them.

Fast Fingers
Loot 50 dead guards with Trophies unlocked.


Thief looting is a reward you get for completing Set 2 of the Thieves Challenges:

• Perform 40 leaps of faith
  
• Climb 1km in distance
  
• Steal 250 currency with Counter Steal

Now that you have your thief looting skill, find some thieves and hire them. Now go kill guards and they will loot all of the bodies for you.

Holy Wisdom
Complete the Hagia Sophia challenge level.


This mission is available once you have obtained all of the memoirs. See "Worth a Thousand Words". It will be its own icon on the map and be located, of course, at Hagia Sofia.

Iron Curtain
Perform a perfect den defense without using the cannon.


The first time you experience a Den Defense is in Sequence 2 Memory 6. You are on the roofs and must place your units and barriers around to defend. You can use everything except for the cannon, which is used with . When the game tells you about it, just ignore it. Put barriers whenever you can. The last wave of enemy is a ram unit. The den must take no damage. You will unlock the achievement in the stats screen afterwards.

My Protégé
Have one trainee Assassin reach the Master Assassin rank.


Refer to "The Mentor".

The Mentor
Have seven trainees reach the rank of Master Assassin.


This task is a working task which involves a lot of time spent going back to it. Essentially you take over dens which give you the ability to recruit assassins. The more dens you take, the more recruits you get. You send those assassins out on missions and rank them to 10. Once the assassins get to level 10, you do a special mission for them after assigning them to guard a den. This is an indicator on the map and not the same way you were ranking them up. After that mission they may be ranked to 15 which is Master Assassin, but you must do 1 final mission in order to get them to have a symbol instead of a number.

Pyromaniac
Complete all Bomb Missions.


These bomb missions are actually more like tutorials. They are given at Piri Reis near the Grand Bazaar in the Imperial District. The icon is black with a white bomb and beakers. It shows up after you progress through the story and learn about bombs. Inside you must go to the wall near his desk. You will see 4 paintings. Each one has 2 missions total, and you must complete one to get the other. They stop shining after you have done both.

Show-Off
Parachute onto a zipline.


Find a zipline and climb up it (not to the very top though, just the part the line is attached to). Now jump, hold and then let go and hold . If you do this quickly enough, you will parachute and then drop onto the zipline. https://youtu.be/4iLPas3fw_8

Spider Assassin
Climb Hagia Sophia, from the ground to the pinnacle, in under 25 seconds.


You'll find Hagia Sofia in the Imperial District (this is the very big building). It's very east on the map, and is positioned right next to a tunnel entrance. Attempt to climb to the point of the top in under 25 seconds. You should attempt this after gaining the hookblade to make it easier on you (the hookblade is story based). https://youtu.be/MYwr6OzcZSw

Tax Evasion
Get your money back from a Templar tax collector.


This enemy type appears at random (or so it seems) and will have a red icon above their heads. They will run from you at sight. Chase them down and press while running to tackle and kill them. It is suggested that they appear upon the happening of the bank deposit. If you rush to the bank when this happens and wait around, you may spot one easier.
