With the release of EA's two-player co-operative shoot fest Army of Two: The 40th Day right around the corner, we thought we'd indulge in a bit of co-op action ourselves (no, not like that). The result? The Top 10 Co-op Games of all Time. If you're after a video game to play with your mate, whether it's on the couch or online, then we've got you covered. Now, who's got our six?
10. Resident Evil 5 - Xbox 360, PS3, PC
Resi 5 might have divided long-term fans of the franchise, and indeed action gamers in general, but there's one thing upon which we can all agree: it worked brilliantly in co-op. When played alone, the delectable Sheva largely acts as an unusually attractive donkey. AI Sheva has no concept of ammo conservation, so most players just give her a cattle prod and force her to carry all their unloaded weapons. But when she's being controlled by a human being, ideally a good friend, the game suddenly takes on a new dimension. The level designs reveal a new layer of subtlety, and before you know it you'll be using proper two-man tactics. And as an added bonus, you're spared the tedium of Chris Redfield shouting "Sheva! Sheva! SHEVA!" over and over and over again.
9. Halo 3: ODST - Xbox 360
The Halo series has always been pretty good for co-op banter, but the recent ODST arguably represents the best effort so far in terms of sociable gaming. In addition to full co-op support for the campaign, there's also Firefight mode - a wave-based challenge that more or less squeezes Gears of War 2's Horde mode into the classic Master Chief mould - even if the man himself is nowhere to be found. We might have seen Firefight's basic structure before, but there's still something highly addictive about the way the difficulty slowly ramps up, making life increasingly painful for your hard-bitten shock troopers.
