Army of Two the 40th is a sequel to the original Army of Two. Like its predecessor it focuses heavily on co-op play either with a human or an AI controlled partner. Following Salem and Rios again, this time they are working for their own private military, Trans World Operations (TWO). 40th day will be set solely in Shanghai rather than the globe-trotting of the first game to create a more believable experience and it will put players in the middle of an ongoing catastrophe and conflict.
