I am not talking about side scrollers and beat them ups.
I am talking about Marvel v Capcom style, head to head fighting games.
Except in MvC, the only times you get 2 characters to use at once is during supers.
Are there any games that has two playable characters on the screen at the same time, on a permanate basis? Like a 2 on 2 fight, or even 3 or 3? And for the boss round, 2 gang up on the boss?
It would be hard for one person to control the 2 characters, so maybe it would be a 2-4 player thing, where 2 players on the same side control each their own characters?
