Army of Two

Army of Two is a third-person shooter released for the Xbox 360 and PlayStation 3 on March 6, 2008. The game takes place from 1992 to 2009. Unusually for a shooter the focus is on teamwork, even in the single player mode. Players will join up with either the game's built-in "Partner Artificial Intelligence" (PAI) or other players "to fight through war, political turmoil and a conspiracy so vast it threatens the entire world." The game has been designed to necessitate teamwork as some missions may be close to impossible to complete without cooperation with the PAI.
