Best split screen games?

What are some good split screen games for 360? A lot of games don't even have split screen, but have online. I just want a game I can play with my friends you know. I googled split screen games, but only found things from like 2007, and there have been a lot of new games since then.

there really isnt much of anything besides halo that you can do 4 person with

some that at least do 2 are ghost recons and rainbow six, gears, cod waw, ultimate alliance

Gears of War 2, Earth Defense Force 2017, Rainbow Six Vegas, Rainbow Six Vegas 2

Halo games and Gears of War games.

L4D, RE5, and Nazi Zombies in COD:WAW is a load of fun.
