Faster Than The Flame
Escape the burning port in under 5 minutes.
Memory Sequence 5:
You must complete the entire fifth memory in under 5 minutes! This is the first speedrun sequence in the game. It consists mostly of platforming sections. Only use slide assassinations and jump assassinations for killing enemies. The slide assassination is the quickest in the game and will save you a lot of time. At the start of the memory there’s a little tutorial that explains slide- & jump assassinations. The time you spend in this tutorial does not count towards the total time! Cutscenes don’t count either. You are even allowed to restart checkpoints when you make a mistake. Keep sprinting all the time and never let go of the sprint-button! During long climbing sections you can press X (PS4) / A (XB1) to climb even faster.
In this video I did it in 4 minutes, 17 seconds to earn the gold reward for beating the fastest time. There’s plenty of room for mistakes when going for 5 minutes. You should aim for 4 minutes, 20 seconds if you want to work towards “The Completionist” trophy / achievement.

Not A Scratch
Assassinate all enemies in the ambush in Memory Sequence 8 without taking a single hit.
Memory Sequence 8:
At the very end of this level you will come to a large room and see a cutscene. Now enemies are spawning in this room (that’s the ambush). Your main objective is to kill all 7 soldiers in the area. Doing so will end the level. Kill all enemies without being hit and the trophy / achievement will unlock upon killing the last one.
If you get hit you can simply restart the checkpoint. Kill the enemies on the upper floor first and then work your way down. Perform some quick slide- & air assassinations to take everyone out quickly and avoid being seen.

Concubine Savior
Save all the Concubines in Memory Sequence 9.
Memory Sequence 9:
In the 9th sequence you will get the optional objective to save all 3 Concubines. They are marked on your map, just like all the other side objectives and collectibles. If you alert the soldiers near the Concubines they will kill them. When this happens you must restart the checkpoint immediately. There will be a red text in the top left corner notifying you when a Concubine has been killed.
Once you’ve safely reached a Concubine you must use the left stick to free her. The second one is the hardest. The first and last are quite easy.

Master Of Stealth
Complete Memory Sequence 11 without being seen.
Memory Sequence 11:
For this trophy / achievement you must complete the entire 11th level without walking into an enemy’s field of view. When an enemy sees you and their vision cone turns yellow (or even red) you must restart the checkpoint immediately! It is okay if you throw fire crackers and noise darts to distract enemies. Do not throw daggers at them though, as they will automatically detect you if you do.
Just follow the exact path I take in the video. If you mess up you can restart the checkpoint as often as you want.

After each section with enemies you will get a bonus award and see your statistics. It must always say “Times Seen: 0”. If it’s not at zero it means you have been detected and will likely have to restart the level from scratch if you’ve already passed the next checkpoint.
