The spring gaming season is well underway and we've already seen a slew of co-op game releases, like Binary Domain, Journey, and Shoot Many Robots, where cooperative gameplay was a focus for the game from the start. Yet we've also seen some major AAA releases, like Mass Effect 3, hit store shelves where the addition of a multiplayer component is something new for the series; or an existing series, such as The Darkness II, swap it's formerly competitive multiplayer mode for a strictly cooperative one. Finally, you have the revival of older games that have had their format completely changed - leaving them ripe for the traditional player vs player multiplayer style to which we've grown accustomed - and still maintain the co-op gameplay (we're looking at you, Syndicate).
