Forums - 3D Zombie?? Fighting Game

I think i recall playing this around the 2010s maybe slightly before that on I think it was on windows 7.
I remember it being multiplayer where you could pick a football player a guitar player maybe a boxer? and there was something else the classes were like that it was a full 3d 3rd person shooter I think where you fought enemies or zombies and could also play with others I don't remember much about the soundtrack or even the sound. I remember it KIND of being an mmo but that very well could be wrong. thanks!
