The problem with these games is that none of them are split-screen co-op which is what the OP is asking for.

I'm sorry, but I think you're SOL on this one and your only option is for the Serious Sam games for split-screen co-op in an FPS.

i have made a blog entry about this topic called "local multiplayer fun on pc"

The only one that has split screen on a computer is Kane and Lynch(I think), but you probably don't want to buy thatnapp123

It's a great game, the bad thing is that you need an xbox 360 pad for co-op.
