This is one of the secret cheevos and it is called "Are you my mummy?"
This is a story related cheevo and therefore it can not be missed.
This cheevo will be awarded upon completion of episode 5: Headshot.
Again like all other episodes this one is very linear and there no reason you should get lost and making it to the end is simply a case of following the markers.
You start off working your way through the city onto the roof tops. You will come to an area with a big bright billboard shining and here you will be attacked by a lot of stranglers and a skinner which gives you another opportunity to gain the following cheevo.
And hopefully if you have been making a conscious effort to kill stranglers without using sensen DOS this is the place I also got the following cheevo. However this may not be the case for you, obviously depending on weather you have intentionally been going for it.
The Fiat lux! achievement in Remember Me worth 36 pointsBeat 15 Stranglers without using the Sensen DOS After a while you will enter a corridor and encounter your 1st elite enforcer, there is a cheevo tied to elite enforcers but that can not be started here.
Whenever you attack an elite it will actually damage you. Only regen pressens can hurt him and keep you alive.
What I did was set my very 1st 3hit combo to all regen pressens and your 1st hit against the elite will damage you but the 3 hit combo will eventually kill him and heal you.
Shortly after that you will be given the task of tracking down a guy named Trace but he will find you first and attack you from his ship. Just keep running and when you are climbing just wait for the rounds to stop before jumping past windows.
While he is chasing you, you will run across a long platform and he will shoot out parts, just run and jump and avoid the gaps, I went down the middle - then right side - back to middle - Then jump to the wall at the very last moment and it should start a slow-mo sequence.
After that you will take on a couple of enforcers, jump over the wall and make your way around the buildings avoiding the fire from trace until you crash through a window.
Now you will enter a room and take on 3 enforcers one of which is an elite.
Once you get to the rooftops, you must steal traces memories so work your way around him and avoid the spot light. When trace shoots the birds make you way back a little and shoot the turbine then run back, up the ladder and jump to trace's ship and steal his memories.
Now make your way back up the building to where trace originally found you and defeat all the enemies. This is quite a tough fight especially on higher difficulties.
Once they are defeated you can use captain traces remembrance to try and unlock the door.
Once you synchronize the door will need a security code.
