Annalise Gallegos' Thumb Drive

 is a book in Prey.

Transcript
[Excerpt from a Readme.txt file found on Annalise Gallegos' thumb drive.]

The drive in your possession contains incriminating evidence linked to illegal experiments performed aboard Talos I in the Psychotronics labs. This includes, but is not limited to:

>>Classified internal memorandums. >>Key research data, spanning several decades. >>Names and roles of all personnel involved. >>Volunteer ID's matched with their real names.

This information will corroborate the existence of an extra-terrestrial species (called Typhon) as well as the fact that all Neuromods are made at the expense of human victims. I harbor no illusions that this will be easy to believe, but I can testify to its veracity - assuming I am still alive - because I was a participant in many of the experiments referenced.

-Dr. Annalise Gallegos
