Carnival of Chaos is an expansion for Thunder Road: Vendetta ( or Thunder Road: Vendetta – Maximum Chrome ) that offers a new way to play. Players race their cars into the arena, collecting wild party items, powerful super weapons, and valuable scrap along the way. This expansion also includes a full set of vehicles and a dashboard, allowing for up to a fifth player to play with this expansion or in the main game.

Unlike a regular game of Thunder Road: Vendetta, the winner of Carnival of Chaos is the surviving player with the most scrap at the end of the game. There is no finish line.
