GW
From the Metal Gear Wiki
GW is the name of the AI system inside Arsenal Gear. It has been programmed to scan the Internet and other forms of media, and eliminate all information hinting at the existance of the Patriots.
[edit] The Manhattan Incident
GW tricks Raiden into doing the Patriots' work by feeding his anticipations and pretending to be Colonel Campbell, tricking him into thinking he's become a member of FOXHOUND (even though FOXHOUND disbanded after the Shadow Moses incident).
GW, like all of Arsenal's systems, was infected by Emma Emmerich's computer virus, corrupting it and causing it's systems to fail (The projections of Raiden's support team began acting strange, Arsenal's RAY units became non-responsive, and Arsenal itself crashed into Manhattan). Following this, the S3 plan was taken over by GW's sister AI, JFK. As part of the S3 plan, GW was sacrificed by being infected with the computer virus in order to mimic the effects of FOXDIE from the Shadow Moses incident.
The remnants of GW were seized by Liquid Ocelot following the conclusion of events of the Manhattan incident.
