How to unlock the A Perfect Organism achievement in Alien: Isolation - Definitive Guide

You should get this achievement at the end of level 2, but interestingly, I think it is missable at that point.

Without spoiling too much, at the end of level 2, you need to get on a tram. Wait by the doors, and when you get in, make sure you turn around and face the open door.

First time, I got in and just faced the same way, loaded up level 3 and nothing unlocked. My save corrupted so I started again and second time I turned around before the level finished and the acheivement popped. Admittedly it might just be me that was unlucky, and it might unlock all the time for other people, but that was what I did.

Good luck!

I like testing what you can get away with in this game. For this achievement, I tried a few times to wait for the tram, then back into it slowly while hitting a box or wall with the maintenance jack. I wanted to trigger the alien and get away with it. No luck. I tried tossing a flare too, but by the time it notices you (thus registering an 'encounter') its always too fast and the tram doors don't close quick enough.

Just letting people know that this achievement is not missable! If you do not get it at the very end of the second level (when you await for the tram) then you will absolutely get it later in the third level.

Story related and can't be missed. You will meet the Alien at the end of Mission 3 when you have to disable the Security Lockdown.
