PAM: Post Apocalyptic Mayhem is a car combat racing game. Drivers compete in violent races across post apocalyptic landscapes with heavily armed vehicles. The game uses a point system where players can earn points in two ways: by completing a lap or by killing an enemy. Focus lies on combat so therefore players will earn more points for a kill than by completing a lap. Each vehicle in the game has its own special abilities. They have three weapons in total; a front attack, a side attack and a rear attack. At the start of a race these are not accessible; they have to be acquired by picking up barrels that can be found all around the race tracks.
The game includes modes for both single player and multiplayer. In single player there are two modes: the arcade mode and the apocalyptic challenge. Arcade is the quick play mode where a single race is played. In the apocalyptic mode the player races trough all tracks consecutively in a rapid succession with little time in between. There are three multiplayer modes. In laps mayhem racing all that matters and kills give no points although they can still be used to slow down the opponents. Kills mayhem on the other hand is all about the kills. The total mayhem mode both are counted and is the same as the single player mode.
