Reading all the e-mails on Talos I will help you to unlock “Press Sneak” Achievement/Trophy (Silver/30G). Emails can be found on both workstations and security stations. Be sure to read the emails marked in bold—they either contain keycodes or trigger optional objectives.
In Prey, you awaken aboard Talos I, a space station orbiting the moon in the year 2032. You are the key subject of an experiment meant to alter humanity forever – but things have gone terribly wrong. The space station has been overrun by hostile aliens and you are now being hunted.
In Prey you can read numerous books and magazines, but to unlock the “Prism Master” Achievement/Trophy you need to read all six volumes of The Starbender Cycle series. There are three copies of each book, with the exception of Book 6. You only need to read one copy of each book to unlock Prism Master.
Volunteers are the missing persons and may only be found on one security roster, the security station in Volunteer Quarters within the Neuromod Division.
Most keycodes on Talos I are randomly generated, changing each time you start a new game. However, there are a few codes that never change.
Keycodes or Passwords can be found near the keypad or the workstation where you need to put them. This can be written on the note, or can be in an audio log or you can find it in the E-Mail.
