An offshoot of West Tek experiments on flatworms from 2075, Only one variant of the floater exists across New California, and is frequently encountered in packs. The Unity harnessed floaters for use as attack and defense, accompanying patrols across the wasteland and protecting key locations in their domain. After the fall of the Master, packs of floaters and centaurs began to appear across California with another used by the Enclave to deny access to the navigational computer onboard the PMV Valdez.
There are three types of elemental floaters in Appalachia as of 2103, generally encountered in groups and frequently found alongside super mutants, who consider them friendly and treat them as companions and attack animals. Floater flamers glow red, have incendiary abilities, and have vertical pupils. Floater freezers glow blue, have cryogenic abilities, and horizontal pupils. Floater gnashers glow green, have pupils in the form of a plus sign, and have acidic abilities.
↑Joshua Sawyer: "I think Floaters are cool critters in the Fallout universe, but, like Centaurs, they have really weird bodies that require unique animation rigs. From an animation perspective, limbless flying things tend to be really cheap (usually), human-like bipeds are cheap, quadrupeds aren’t too bad. Once you start getting into creatures with multiple heads, snake bodies, tentacles, etc., they get really expensive. IIRC, we talked about having Floaters but we just didn’t have the animation time for them." (Joshua Sawyer on Tumblr)
