Description taken from PC version of this game

1nsane is a fully 3D off-road derby game designed with a distinct focus on multiplayer Internet play. Players choose from one of 20 different vehicles to drive through virtual versions of several locations around the globe. Up to seven other players can meet with their own vehicles for an eight-way demolition derby with no boundaries or rules. There are no mounted guns or futuristic weapons, so players must disable their opponents with strategic, well-placed smashing and ramming, until only one driver remains. ~ T.J. Deci, All Game Guide
