We are working on this long awaited mod for Return to Castle Wolfenstein (2001). You'll be able to play the whole campaign + new maps with your friends!
Coop for an old classic game like RTCW???!!! Oh it gets a 10, it's got a few bugs but I'm sure they will fix these later on. A very well done mod , they should update the installer to find my Steam folder for people that bought it there they might be confused where that is in the C:\Program Files (x86)\Steam\steamapps\common
Coop campaign seem to skip some mini bosses, some objectives and feels like sometimes whole locations, have some issues with level endings/loadings (players get stuck in each other, "ran out of memory" errors etc).
Nonetheless, it's fun mod to mess around with friends and travel back in memories of good old times with this game.
