EA Montreal today announced Army of Two: The 40th Day will ship on January 12, 2010 in North America and January 8, 2010 in Europe.

The sequel to the 2008 co-op shooter sees the return of the two-man private military team, Salem and Rios. Trapped in the middle of Shanghai as it falls under attack, the two must work as a team to survive enemy assaults and escape the city collapsing around them. Gamers who pre-order Army of Two: The 40th Day will have exclusive access to the game’s new multi-player mode, ‘Extraction,’ at launch. This mode will be unlocked for all other players one month after the game ships.

Army of Two: The 40th Day features a redesigned multiplayer with four multiplayer modes including ‘Extraction’. ‘Extraction’ pits a team of four players against a series of enemy waves as they move from point to point in the ruined city. Players must strategize as a unified team to combat the different forces of the 40th Day Initiative while trying to get out alive.

Army of Two: The 40th Day will be available for the Xbox 360, PS3 and PSP. For more information, visit the official site.
