The series has historically been considered a clone of Grand Theft Auto that later positioned itself as more "gleefully silly" in comparison. In combat, players select weapons from a weapon selection wheel, [d] including regular pistols, submachine guns, shotguns, and rocket launchers alongside special weapons such as UAV drones and a fart-in-a-jar stun grenade. Player melee attacks include running attacks such as DDTs and a purple dildo bat. Players may use vehicles to navigate the city, including a hover jet (known as the F-69 VTOL) and a pixelated retrogame tank that are unlocked through story missions. Once special vehicles are unlocked, they are in unlimited supply and can be delivered directly to the player-character's location. Player actions are intensified with what Volition calls the "awesome button", where for example the player will divekick through the windshield into the driver's seat of a car. The main story campaign missions can be played alone, or cooperatively either online or via System Link offline. [e] Some elements are added to the campaign for the second player. There is no competitive multiplayer, but a "wave-based survival mode" called Whored Mode that supports up to two players.
