Vehicular Homicide is the revised and retitled version of Diecast Mayhem, a miniatures arena combat game by Radioactive Press. The game is intended for use with common diecast vehicle toys instead of custom miniatures, thus making it particularly easy for new players to pick up the game. Using these rules, players can design there own vehicles—including automobiles, tracked vehicles, walkers, hovercraft, and aircraft—and arm them with weapons and other special attachments. The final survivor in head-to-head combat is the victor.
