Floater (Fallout: New Vegas)

Floater is a creature cut from the final version of Fallout: New Vegas. They appear in game files in name only, using the centaur's assets.

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

Biology
Through producing and storing noxious gases in their floatation bladders, floaters are able to hover above the ground.

Behind the scenes
Floaters were cut from Fallout: New Vegas due to them being too complex to animate with the limited time and resources Obsidian had to make the game.
