The player has an opportunity to attack Earth with the Death Ray. After the room with the generator nest is cleared out, the ray can be configured to aim at Earth near Algonquin National Park in Ontario, Canada. The explosion spans around 350 miles, or 550 kilometers (past Detroit or Cleveland). The controls on the right console change where the Death Ray aims, and the right-hand control on the left console fires the Death Ray.
