Floater (Fallout)

Floaters are hostile mutant creatures that likely originated from the FEV-infected flatworms mentioned in the FEV experiment disk. Later, they were further enhanced by the Master's experiments.

Biology
Floaters hover through the air by manufacturing and storing noxious gases in their flotation bladders. The gasses that allow them to float are also highly flammable, which makes them incredibly vulnerable to fire, but the insulative properties of the gas prevents electrical attacks from harming them. While they are not very intelligent, they move fast and can be difficult to kill, especially if a group of them manages to surround anyone unwary. Their body parts have unique names such as "ganglions," "ovipositors," "fore mouths," and "float sacs."

Gameplay attributes
They are often found in groups with centaurs. Through producing and storing noxious gases in their floatation bladders, floaters are able to hover above the ground.

Floater
Floaters are durable creatures, and move very quickly due to their unique ability to hover. They often travel in groups with super mutants and centaurs, and can pose a great threat to anyone unprepared for combat.

Nasty floater
If normal floaters are bad, then the nasty floaters are far worse. Even more durable and tenacious than their counterparts, they are indeed capable foes. Just like common floaters, they are very susceptible to fire, due to their flammable gasses.

Appearances
Floaters appear in Fallout and Fallout 2.
