GW

GW is the name of the AI system inside Arsenal Gear. It has been programmed to scan the Internet and other such Media and eliminate all information hinting at the existance of the Patriots.

GW also tricks Raiden into doing The Patriots work by working on 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)
