So I'm having a LAN with a couple of mates in a week, but we don't really have any good games to play. Got any tips? We used to play alot of Diablo 2 on LANs but we're looking for a breath of fresh air =P We don't mind another "dungeon crawler", it would actually be a great thing. We're looking for something cheap/free to play together. We've played some LoL aswell, and well... It works, but it's not a game that I personally like very much.
So do you have any cool free/cheap games that has a good CO-OP? Feel free to share it here =D
-edit-
Other genres are ofcourse welcome aswell =P
