Failed FEV Subject

Failed FEV Experiments are mutated humans who can be found in Vault 87.

Background
These creatures are hideously mutated vault test subjects, all having (presumably) cancerous lumps covering their bodies. Their upper body is much larger than of a normal human, but their legs have remained in somewhat normal size, and their heads still have some human-like characteristics. It also seems they have gained a fair amount of muscle on their upper body, much like super mutants. They wear torn Vault 87 jumpsuits like the other experiments. If you hacked some of the terminals you'll find out a vast majority of the deaths logged in the computers were caused by this experimentation.

These failed experiments can be found in Vault 87 in the test labs. They are all dead and their holding cells have a small amount of radiation. According to Vault 87 laboratory computer, they are among many of the FEV test subjects deceased due to their brains being unable to support even the most simple actions of human body and behavior after being injected with FEV.

Development
The two Failed FEV Experiment's entries in the G.E.C.K. suggest they were originally planned to be live enemies at some point, with their S.P.E.C.I.A.L. attributes are already written out, and in possession of Super Mutant dialogue.

However, they have no AI or animations, so upon resurrection they will lie where they are, spouting Super Mutant dialogue and appearing as red blips on the Radar. Any damage to their bodies, however, will cause the game to freeze.

They serve no purpose except to add to the background of the FEV experimentation at Vault 87.

Appearances
The Failed FEV subject only appears in Fallout 3.
