I'm off to a LAN with some of my friends this weekend, however there's only 4 of us and competative games tend to get a bit ugly, so I'm really wondering what kinda co-op games are there out on the PC that all 4 of us can play either around 1 PC, or 4 PCs via Lan/internet.
At the moment System Shock 2 is kinda ruled out as we've done that before. We enjoyed Alien:Swarm a lot, and like games like Swat: 4. I've got R6:Vegas penciled in, but I really can't think of much else that's come out. Is Monster Madness: Battle of Suburbia worth picking up even just for a couple of hours gameplay? And are there any ways of legally getting some old classic arcade games, such as TMNT, or Gauntlet (Curse you xboxlivearcade!).
Alternatively are there any 4 player competative games that are outside the usual FPS and RTS crowd, e.g bomberman, or something like Settlers of Catan.
Any suggestions at all appreciated really.
edit: there's probably going to be an internet connection.
