I installed this game using playonlinux. I made virtual disk with wine version 1.5.20. On wineHQ somebody wrote, that it works without change any settings, but I had to mark button in winecfg -> graphics -> emulate virtual desktop. (Otherwise the screen was black when I start the game) This was may be caused by Nvidia proprietary driver, but when i tried Novua open source driver it was much worse (a lot of errors). Now almost everything works perfectly fine. But I am not able to run multiplayer (LAN game). On wineHQ is how to: http://appdb.winehq.org/objectManager.php?sClass=version&iId=3906 So I coppied archives to the virtual drive for crusader /home/scretch/.PlayOnLinux/wineprefix/crusader/drive_c/windows/system32 and loaded them in winecfg.
Now when i host the game, nowbody can see my "server" (we use hamachi). When i join the friend's "server" (I see host) the game freeze.
Other games (counter strike, hedgewars,...) work without problems with hamachi.
