Army of Two: The 40th Day, sequel to Army Of Two, was developed by EA Montreal. Like its predecessor, Army of Two: The 40th Day focuses heavily on co-op play either with a human or an A.I. controlled partner. The game follows the continuing misadventures of Salem and Rios now running their own private military corporation, Trans World Operations (T.W.O.). Counter to the variety of worldwide settings of the first game, Army of Two: The 40th Day is set entirely in Shanghai to create a more believable experience. This squarely puts the player(s) in the midst of the outbreak of war in Shanghai.
The game added a new feature called "two-man tactics" to give players a greater amount of choice as to how they will tackle each challenge in the game. Other new features are an overhauled A.I. system, new co-op partner controls, a realistic materials system that allows shooting through walls. Also the weapon customization has been upgraded; now you can put any part of a weapon onto another weapon, which changes both the look and stats.
At the end of the first game, Salem and Rios took down the SCC corporation, thus making them start their own private military organization called TWO (Trans World Operations). There is a cutscene with Rios and Salem in a helicopter along with Cha Min Soo and Viktor Roshanko, weapon and armor dealers, and their investors. They ask Alice to be their contract filer and she agrees. In this second installment in the series, Rios and Salem travel to Shanghai for a reason that is "yet unknown". As the two are there, the city turns to chaos and an unknown army has attacked for an unknown reason. It is the choice of Rios and Salem to fight their way out, or to discover the mystery of the 40th Day and save the city.
