KarBOOM is a fast-paced local multiplayer car-combat game for Windows, Linux and Mac. Knock other players out the ring, chase the flag, play kar football, and bet on how long you can survive with everyone hunting you! Play in teams or every kar for itself!
Automatic port-forwarding using UPnP, online rounds, plus a bunch of menu improvements. UPDATE: Includes a DLL whose absence was causing errors on some computers.
