This strange artifact of alien origin was created to serve as a beacon for the martians. It has turned nearly every living person around it, including scientists studying it, Rebel soldiers and even survivors of a nearby plane crash into zombies. The beacon causes a power surge that destroyed the floodlights around it, and possibly even caused the plane crash which resulted in civillians joining it's undead horde. The artifact is protected by Monoeyes which hover around it, the zombies it creates, and its ability to drop powerful Monoliths that crush anything beneath them.
