Last of Us multiplayer is pretty solid and there is plenty of people playing and locally organized championships. I have now 20+ people on PSN that plays it with headsets, entered a team with other 3 players and will participate in my first championship just for the fun. Infected? Why? I recon a coop mode would be cool, fighting infected alongside your friends, that would be cool. But the normal 4 vs 4 MP is great.
