In Prey's "Who is December?" mission, you'll eventually need to search Alex's room for the escape pod key (the EP01 keycard). If your experience is anything like ours, it's the most difficult item to find in the game. In this guide, we'll show you where to find it (and then continue through the end of the mission).
Search Alex’s Room for the Escape Pod Key (EP01 keycard)
Alex’s suite is on the Executive Suites level of Crew Quarters (it’s right next door to your suite, actually). You can get the code for the Executive Suites grav lift from a supply closet on the second floor to the left of the Yellow Tulip bar. (It’s easy to find — it’s got a fabricator in it as well.) Take the grav lift up and make your way to Alex’s room.
Clear out any goodies you find in his room, then turn your attention to the globe next to his bed. Pick it up to find the EP01 keycard underneath — this is the keycard you’ll need to access Alex’s escape pod.
Escape Talos 1
Head back to Alex’s office in the center of the Arboretum. You have two ways to get to the escape pod. If you have hacking 4, you can use Alex’s computer to lower a bridge from the escape pod to the roof of Alex’s office. This is the easy way.
If you haven’t maxed out your hacking, or you just like a challenge, you can use your GLOO gun instead. Climb up to the roof, then look for the wooden shelter-things. (Google tells us these are called pergolas, but we’re pretty sure that’s a made-up word.) Get to the roof of the "pergolas" and turn toward the escape pod. Use your GLOO cannon to give yourself footholds along the metal girders.
When you get to the escape pod, use the EP01 keycard you found in Alex’s room to get inside. Turn around, then push the button to close the door. Then you can use the computer screen to launch the escape pod and just kind of … quit.
Obvious warning: There are spoilers in the video below.
This will earn you the Abandon Ship achievement/trophy. And it is technically an ending to the game, so … congratulations?
