Trapped in the middle of Shanghai as it falls under attack, the two must work as a team to survive relentless enemy assaults and escape the city collapsing around them.

In Army of Two: The 40th Day, private military contractors, Salem and Rios must fight their way through Shanghai to survive a carefully orchestrated series of catastrophes that are dragging the massive city to the brink of ruin. Jonah, the mastermind behind the 40th Day Initiative, has amassed an army of skilled soldiers to level the city in his attempt to rebuild an empire according to his vision and ideals. Now, the Army of Two must fight their way through ravaged city districts as they try to beat the odds.

As the action heroes fight for survival in a city under siege, the soldiers must make moral choices cooperatively that affect the pair as a team. Each moral decision sets players on a course that affects the gameplay and direction of the storyline. Bachalo and Jock have been enlisted to illustrate the long term impacts of these 'morality moments'.

The sought-after composer, best known for his work on the blockbuster films 300 and Watchmen, is crafting an immersive score that will highlight the epic co-operative battles gamers and their friends will face in the first major videogame release of 2010.

"Set in Shanghai in the middle of a major disaster,Army of Two: The 40th Day dials up the action through a series of powerful scenes where players have to work together as a team to survive and escape the city," said Lewis James, Audio Director at EA Montreal. "Tyler examined every part of the game and how players will move through the world to craft a score that truly represents their actions and the chaos unfolding around them."

"The 40th Day is one of the most intense games I've seen," said Tyler Bates. "The setting, characters and action in the game provided me the perfect backdrop to create an equally intense and dramatic score that complements the gameplay."

With more than 50 films and 15 years experience, Bates is one of Hollywood's most sought-after composers. In addition to Watchmen and 300, he has scored hit films such as The Day the Earth StoodStill, Rob Zombie's Halloween and Halloween 2, and Showtime's hit comedy series "Californication".

"Tyler Bates' score forThe 40th Day is not only a stellar addition to this tradition but takes the Army of Two franchise to a whole new level," said Steve Schnur, Worldwide Executive of Music and Marketing. "Most of all, our collaboration with a composer of his caliber furthers EA's continued commitment to creating the most groundbreaking new soundtracks in the entertainment industry."

Army of Two: The 40th Day features a more robust and redesigned multiplayer experience with four unique multiplayer modes including ‘Extraction’. ‘Extraction’ pits a team of four players against a series of unique 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.

Gamers who pre-order Army of Two: The 40th Day now will have exclusive access to the game’s all-new explosive multi-player mode, ‘Extraction,’ at launch. This mode will be unlocked for all other players one month after the game ships.
