BBQ C2 is the only stand-alone Carmageddon 2 installation made to play against eachother. It runs best on LAN (even on modern systems) but can also work over the Internet via vLAN, direct connection or through a master server (most cases require a very high connection speed though).
This is Errol's monster mod of Econobrick's old 2CV.
Pick up afterburner or even some turbo boost and this beast doesn't need its front wheels anymore.
