As long as you're on 360, online is fine.
Even I got a couple of wins. Used Team Clockw0rk (Strider/Doom/Sentinel). Turns out, that team fits how I want to play this game PERFECTLY. Now, I know who two of my characters are in MvC3. I'm looking at Doom/Sentinel/X-23,Wesker,Deadpool. I can't decide yet.
