Splosion Man HD Gameplay (XBLA) - 2p Coop 1-1 and 1-2
http://marketplace.xbox.com/en-US/gam...
I joined a game to see what the multiplayer was like. The guy didn't have a mic so it was hard to communicate and this was my first time playing coop mode. I joined a 4p coop after and it was a mess.. you definitely need 4 players with microphones to get through levels (there are places with 4 switches that you all have to activate at the same time)
I definitely recommend this game. For 800 points it is a must buy!
