With the proliferation of social networking (MySpace, Facebook, etc.) across the Internet and the growing community of gamers through friends lists on Xbox Live, Playstation Network, XFire, Raptr and Steam, gamers have never been this well connected to each other. Perhaps that's why cooperative gameplay modes are seeing a surge in popularity these days. Red Alert 3, Gears of War 2, Call of Duty: World at War, Left 4 Dead and Resistance 2 are only a few of the new, high-profile titles that prominently feature cooperative modes. Including a cooperative mode is not a new idea in gaming -- although some of these titles take it in interesting directions -- but versus modes were the multiplayer standard for so long that it's great to see co-op come back."
