Mario kart source mod for Half-Life 2

Mario Kart Source aims to bring the fun and excitement of the Mario Kart series to the PC though the powerful Source engine used in Half Life 2. We hope to create the ultimate version of Mario Kart (MK) by combining all of the best aspects into one game. We're not simply recreating one version of MK, but using the best parts of each. We want to have all the traditional weapons, characters, and maps but also bring out new weapons that make game-play interesting. We're redesigning the maps so that they keep their appeal, but truly utilize the power of the source engine. We plan to have at least 16 different characters, all the ones you know and love as well as some others from the Super Mario World.
