Zero Gear is a racing game developed and published by NimbleBit. In the game the player controls a kart and tries to finish first trying to make the other players fail by using weapon pick-ups. The game officially supports up to eight players (though servers with up to 16 slots are possible), allows for customized carts and drivers, and has multiple game modes such as "Race", "Tag", "Goal", and "Target."

A fifth mode, "Sumo," was added in an update on February 19th, 2010, the last update to date. The game appears to have lost all of its support from NimbleBit as of March 2010.
