For those who remember the multi-platinum first installment of EA's co-op shooter Army Of Two in 2008, you'll be eager to once again take control of mercenaries Tyson Rios and Elliot Salem for some gratuitous mayhem.

Army Of Two: 40th Day, set in a Shanghai rocked by a man-made disaster, once again focusses on two-player co-op play to get the most out of the title - seeing you and a buddy having to team up and coordinate attacks in order to prevail. Loners can play the campaign too, assisted ably by a computer wingman, but we strongly recommend getting human help. However, unlike the first game where co-op moves could only be used at specific times, in 40th Day you can use these special tactics whenever you choose - a big plus.

This new dimension, combined with amazing online mulitplayer options, being able to use tactics such as feigning surrender, simultaneous sniper shots and morality choices that affect the story of the game as it progresses should leave you with more than a tingling sensation in your trigger finger.
