Looking for an old game

I’m trying to remember the name of a game that i played a long time ago could someone help me?

The game had zombies and it was pixel game. you’d spawn in the city surrounded by broken down cars. you’d also have some computer characters with you. there was a bar you could go into and some zombies would be there and some zombies threw like ninja stars, there were a bunch of variants. at one point you could drive a bus and run over a bunch of zombies. there was one area in a graveyard where you could fight some type of bat but if you died you’d respawn in the place you spawned in (the city with the broken cars). i think there was a nurse you had with you, and some other people but it gets foggy. i’m the beginning while choosing a game mode there’s some type of guitar riff that plays with each option you hover over. once you choose a certain game mode (i can’t remember which) your character gets dragged from hell i think and you start fighting and surviving in the world. that’s what i really remember.

could someone help me find the game? i’m pretty sure it was on the xbox360 but i just cant remember the name.
