Project REVENANT

Project REVENANT was a highly classified program run by the Office of Naval Intelligence as part of several measures taken to design soldiers capable of fighting in conditions even Spartans could not survive. The result was an entirely new form of combatant that combined the features of man and machine on levels not even the cybernetics of the Spartan programs could achieve. As its subjects were mostly deceased Spartans, whose remains (if intact) were cryogenically preserved, REVENANT converted organic features and processes into mechanical ones, reshaping the body into a vaguely human-shaped husk filled with hardware. As such, the body and armor became one entity, fused together. The brain was scanned and the resulting artificial intelligence was housed in a neural lace that filled the entirety of the cranium, its processing power contained in the REVENANT's armor. Each REVENANT was not a truly "smart" AI, rather, an impression of the deceased Spartan that functioned as part of a network.
