Mutant bat (Van Buren)

Mutant bats are creatures found in the caves near Blackfoot.

Characteristics
Be careful not to let them get too close because you can be killed if too many come towards you all at once. If you manage to kill them, you can loot them to get bat guano.

Appearances
Mutant bats were to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios.
