Games with Cooperation-Mode

[Arglblargh]

Hi there,

we are searching for a game with a very good cooperation-mode. We don't like those arena-fights like unreal tournament etc.
We need a story, some action and some quests. Is there anything like FarCry for two players? Is "full spectrum warrior ten hammers" what we are searching for or is there something better? It's not a must to be the newest game.

Thanks :thumbup:
