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 favors, powerful super-weapons, and precious scrap along the way. This expansion also includes a full set of vehicles and a dashboard, so you can play with a fifth player using this expansion or in the regular game.

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