Co-op is fast becoming a staple of many multiplayer-enabled console titles these days. The notion of playing together as a team towards a common objective is the new black, as opposed to simply fragging the hell out of each other for kicks and gamerpoints (you know who you are). However, very few developers can stand up and honestly say their game was built with co-op in mind. Some games pull it off incredibly well, while others offer a co-op mode that feels tacked on and more like an after-thought than a core feature.
