Looking for Coop PC games!

Ok, as the title says I am looking for a Cooperative game (online) that i could play with my friends. Last that i had found was Rune...wich was not too bad when your playing 8 friends together...but still not the best. I'm looking for something of the same sort...were i can play a full game Cooperatively, preferably FPS or Action.

Anyone have any ideas?

If you don't have a problem with playing a somewhat older game, try Serious Sam in cooperative play. It's great, you can go through the entire single-player campaign with your friends. This holds for both Serious Sam: The First Encounter and The Second Encounter. Apart from these, Serious Sam 2 should also have this feature.

And they're as much a twitch FPS experience as you can get.

This will be very interesting Left4Dead. K_r_a_u_s_e_r

Woot! just checked it out, exacly the kind of game i was looking for, right now looks like were gonna go for some Coop mod on Half life and Doom 3. Id go for Vegas...but...my friends cant run it :(

Guild Wars, Diablo 2, Diablo 1, Baulders Gate 2Cerza

Hmm..action or FPS...not rpg

Well, if you are looking for action, try Warcraft 3 "DoTA" map mod.

I know its from a RPG game, but its more action pack based. But too bad its just 5 person per team max with 2 team against each other. Tight teamwork needed in the game. You can get more information and the map from www.getdota.com and www.dota-allstars.com

I'm always looking for coop games too, especially fps! What about The Mark? It didn't get good reviews :P, but it does supposedly allow you to play the campaign cooperatively, which is hard to find. Any one tried the coop part of the game?

Have you tried F.E.A.R. coop ?
