Well my first 2 levels I'd love to have was the Rival and Boss Arena from Playstation Alltstars Battle Royale, but they were'nt playable or unlockable. I'm really hoping for them as DLC.
I like the idea of the U2 level. And that DmC limbo falling stage idea is bad arse(cuz u can't curse). And who wouldn't want a snow level. I'm also really looking forward to a Medievil level. Yeah, you feel me.
