Mr. Maim is a free first-person shooter where you play as a black and white mime who fights off hordes of clowns who want to paint him. It's funny that there are no weapons in the shooter, but the skills of the mime himself cope no worse. The goal of the game is to destroy 200 clowns that appear in the circus arena. The hero has four types of weapons — analogues of a knife, chainsaw, shotgun and grenade. Some attacks restore health, and there are also taunts in the game, including the middle finger.
