Post Apocalyptic Mayhem turns racing into a collision-heavy fight across apocalyptic tracks. Players drive heavily modified vehicles, pushing for the finish while attacking rival racers with vehicle-specific abilities. Its physics-based driving model emphasizes speed and punishing impacts, giving the races a rough-edged feel rather than treating combat as a separate activity.
Each vehicle has front, side, and rear attacks. Special Ability Barrels placed along the tracks grant abilities when driven over, letting players choose when to unleash them. Routes include alternate paths, tight funnels that bring vehicles close together, and large jumps, so track layout shapes both the race and its opportunities for confrontation. The game also includes multiple race modes, with driving and battling skills both in focus.
Steam achievements and leaderboards add recorded results and goals beyond the individual race.
