Floater (Fallout)

Floaters are hostile mutant creatures found in the Fallout universe. Their origin and etymology are unknown (although they are likely to be the FEV-infected flatworms mentioned in the FEV Experiment Disk), but they are often found in groups with the Centaurs.

They are completely immune to electrical damage, but have no resistance to fire damage.

Appearances in games
Floaters appear in Fallout and Fallout 2.
