Abandon Ship
How to Get All Endings in Prey
Early on in the game you are given the optional objective of heading to Alex’s suite in Crew Quarters and retrieving his escape pod key. If you went and did that, then you’re able to get the most scumbag of the endings. You can actually flee all of your responsibilities and leave the Typhon and surviving humans to fend for themselves.
Once you’re able to access Alex’s pod, just do so. January will try to talk you out of it, but you can just keep going and initiate the escape system. Even your brother will try to give you some guilt. However, you can still just blast off. The ending is interesting, though, as it shows that the threat wasn’t actually real. You can hear Alex saying “we failed, this isn’t the one,” and a woman’s voice saying to “start over.” You’ve failed the test.
