"It’s easy to forget, but PlayStation 3 isn’t just about big-budget single-player games. Indeed, while Sony’s flagship home console is host to some of the finest, compelling slices of solo-based gaming this generation, it’s also home to some truly breath-taking cooperative experiences to boot. Whether it be good old fashioned split-screen co-op or taking the action online, PS3 gives players more than enough incentive to get on the blower to a couple of mates and team up for a session. And, while it’s fine to cultivate your competitive nature by going head-to-head, every now and then we just want to put aside any friendly rivalry and combine our gaming expertise to bring down a massive boss or lead an assault on an enemy base. Wouldn’t you agree?"
Most of those co-ops are just horde battle modes. We need more co-op games that actually do something special for co-op. We need a sequel to Syphon Filter the Omega Strain and a console Monster Hunter.
Resistance3's co op is pretty much playing the campaign with a buddy offline or online. Not bad, but definitely under R2's shadow in terms of co op.
