"EGS Tapes" is a series of audio recordings of squad members lives before they had been recruited. The audio segments have been recorded on cassette tapes in either therapy sessions, by the individual's own will, or by surveillance microphones. These tapes have been a key element in discovering what truly lies on the other side of life. Some tapes may appear to sound vague while others are littered with clues. It is also believed that some tapes may have been recorded postmortem.
EGS Tapes of Volume 1 are the original EGS tapes made by Andrew Blaze.
