HIDE RUN SURVIVE
Complete “The Quarantine” without being killed by the Alien
Alien Isolation HIDE RUN SURVIVE – Achievement / Trophy Guide
You have to complete the whole mission in one run. If you die and load a manual save the achievement/trophy won’t pop.
After you accessed the computer in MORLEY’S OFFICE (3:56) halfway through the mission you will see the alien coming out of the vent. Never run from this point on and make your way to ROOM A-29 (5:50) and get the keycard. Always check your motion tracker and back the same way you came in. When you talk to the doctor for the last time, make sure to run quickly to the elevator or the alien will get you.
