Army Of 2 : The 40th Day for PlayStation Portable (PSP) by Electronic Arts

COMPATIBLE WITH PSP Highlights: The Evolution of Co-Op - ARMY OF TWO: THE 40TH DAY has been built from the ground up with a focus on an incredible cooperative experience. The result is a bigger, better, more organic and immersive co-op experience that lets you put your best two-man tactics to use whenever and wherever you want. Survive the Disaster - A carefully orchestrated series of mysterious catastrophes is dragging Shanghai, China to the brink of ruin, and now the Army of Two must fight their way through ravaged city districts as they try to beat the odds and uncover the secret of the 40th Day. Never-Before-Seen Weapon Customisation - Blaze into battle with more weapons-and even more upgrades per weapon-than in the original game, while the action reaches new levels with strategic gunplay: the weapon you choose and customise defines how you play the game. Will you go for the barely controlled chaos of the aggro focused weapon or design a silent and deadly flanking weapon? The choice is yours!
