Well, if you lived in the world of RAGE that is. I love a good co-op mode in games these days since not much in the way of innovating multiplayer modes has happened in the past couple of years. It is more fun to have a great co-op session than it is a multiplayer session. There is some crazy split-screen action on the PC version in this video going on. Not sure if that is in the game or not. Once we get word from Bethesda I will update this post.
[update] Looks like only consoles have split-screen. The split-screen you see in this trailer for the PC is not real.http://www.youtube.com/watch?v=fichOmBDwYA
