Great 4 player games?

So I am up here at college and my buddies and I love to play the 360. We don't have many games that support 4 player and are still fun. We are stuck with playing COD, GOW and Halo pretty much all of the time. Occasionally we will play The Club, but other than that, its about it.

While I love shooting games just as much as the next college guy, I would like some variety in the few games that we play. I am not looking for any sports games, because we just don't like them. I have Castle Crashers and a few other XBLA that are 4 player, but we just don't seem to play them much at all.

So basically what 4 player games do you guys like? Perhaps some lesser known titles that have great MP or something? Any input is welcomed and appreciated.

The game from Dorito....?

I'll try it but I was hoping for a game with more depth.

And I have tried Marvel UA but they are terrible and yes I have Rock Band

any sport game really try; nhl 09 its good.small arms,and left gor dead(need two box,s)

Try Army of Two.

Try Army of Two.

maybe some rainbow six vegas 1,2... and guitar hero wt or rockband 1,2

Hm thanks for all of the replys, but I already have all the music games out, they just arent those kind of guys though. We dislike sports games as I said in my original post and although Army of Two is great 2 player, it is not 4-player.

Plus again Left 4 Dead is not 4 player split screen, which is what I am looking for. We do however each have Left 4 Dead now, as I finally convinced my friend to pick one up so we can play 2 in one room 2 in the other, but the main thing that I am looking for is 4 player split screen. I have pretty much all of the main titles you can think of, I am looking for some more underplayed games that have great 4 player split screen.

Marvel Ult. Alliance, outstanding 4 player game

Conflict dessert storm for xbox 1- imo i think its the greatest co op game. Sure it may not be nice looking and plays like halo its def fun to play with feinds

If you like rpgs try tales and eternel

aigis wing

fuzion frenzy 2

Theres not much, developers should focus on local play on video games, nothing is better than online is playing with buds.
