At a Lan party a short while ago, we had a ~2hr Killing Floor session..
Killing Floor is a UT2k4 mod that *requires* everyone to communicate and work as a team to hold off hordes of zombies, and it was awesome

So, spec me some more team based games I might like!

I'll start the list:

Killing Floor (UT2k4 mod)
Alien Swarm (UT2k4 mod, being developed on Source)

I *do* own TF2.. I guess I should give it a go at some point

Is it mostly TDM, or CTF? I'm a Team Fortress n00b

Kane vs Lynch multiplayer bank heist.

You all start on the same team, and share the money, but if one of your team mates die, either by enemy fire or by your own gun, then they turn into a cop and try to kill you.

Its very novel, do you kill your team mates making it harder to get the money, or take less money and work as a team?

That sounds quite cool, but neither me nor anyone I know owns the game :/

I'll see if I can find it el cheapo somewhere..
