Desert stalker

Desert stalkers are creatures found in the American Southwest. They are giant, mutated antlions.

Characteristics
One of the lovely predators unique to the Sonoran desert and its outlying areas, the desert stalker attacks by burrowing up from the ground underneath the victim and dragging them back down into the earth with razor sharp mandibles. Desert stalkers have an uncanny ability to hunt for the weakest person in any group; picking them off while they're the least aware of danger, usually. catching the rest of the group off-guard, as well.

Appearances
Desert stalkers have not appeared nor are they mentioned in any published game. They were to appear only in Van Buren, the canceled Fallout 3 by Black Isle Studios. It is not certain if they will appear in any future Fallout game.
