it says in the magazine there will be 16-player matches, 4 player battles and even 1-on-1 showdowns.
there is gonna be co-op, team deathmatch, deathmatch n more. you can create ur own character on multiplayer. something about catch me if you can. you can also get away from cops while they are arresting you by puttin ur hands over ur head, startin to kneel and then run! lol
