My friend came over for some LAN gaming and I tried to get the Co-Op campaign to work over LAN, and it would not work. We tried doing a standard LAN Listen server for multiplayer and THAT worked, so I have no idea why the co-op won't work. If anyone knows whats up, let us know, my friend and I want to play through this game's gripping, compelling campaign so we can capture lettuce flags and learn why people respawn in Unreal Tournament.
