Primarily a vehicle simulation game, the player controls one of a number of possible vehicles in order to complete objectives. The vehicle used could be an aerial craft, defence emplacement, or surface craft, and is usually armed with a primary weapon (with unlimited ammunition) and sometimes secondary weapons (with either a limited or infinite supply).
