Army of Two is a third-person shooter video game developed and published by Electronic Arts, released on March 6, 2008 for the Xbox 360 and PlayStation 3 consoles. The game is centered upon two mercenaries fighting through war, political turmoil, and a conspiracy from 1993 to 2009. Focusing on cooperative strategies, Army of Two‘s main feature is the necessity to use coordinated teamwork to accomplish the game’s goals. While the game is meant to be played with another human as a partner, a “Partner Artificial Intelligence” (PAI) is also included and programmed to follow the player’s strategies. Dependence on a partner (whether human or PAI) is so pronounced that most objectives are impossible to complete without it.
Army of Two is one of the first games released for the Xbox 360 and PlayStation 3 consoles that feature region-locked online play. EA claims that the region-locking is to prevent network lag caused by players from multiple regions, and to prevent the Asian region console owners from playing the U.S. and European version of the game, as the Asian version has been censored to meet certain requirements (notably, the shooting of already dead bodies in the game). A sequel titled Army of Two: The 40th Day, was released on January 12, 2010. On August 11, 2011, Electronic Arts shutdown the online multiplayer servers for the game.
