Vehicular combat games (also known as just vehicular combat or car combat) are a sub-genre of vehicle simulation video games where the primary objectives of gameplay include vehicles armed with weapons attempting to destroy vehicles controlled by the CPU or by opposing players. The genre normally features a variety of different vehicles available for play, each with its own strengths, weaknesses, and special attack abilities. Players may also unlock hidden vehicles by completing certain in-game tasks. Traditionally, vehicular combat games focus on fast-paced action inside the vehicle, rarely, if ever, concerning themselves with role-playing or other elements, Metal Max series being an exception. Games may include racing themes, but they are generally secondary to the action.
