Route 666 is a one-way route, where the penultimate segment of the Festival of MotorStorm: Apocalypse takes place. In this segment, Big Dog rides his chopper along this route to lead a DuskLite helicopter away from the carrier.
The course itself consists of some segments of highway, and a harbour, as well as the edge of a very sharp drop-off to an earthquake-created valley.
- The DuskLite helicopter will chase and fire rockets and bullets at Big Dog as it follows him along this route.
- The number 666 is often associated with the number of the Beast.
- This route is not available for selection in Wreckreation.
- It is perhaps a reference to the famous US Route 66.
