originally inspired by the "crazy mutagens" mod, i wanted to be able to mutate things a little further... there's a fridge just outside vault 101 (on the road) with the weapons.
It's fun to walk into megaton, take good cover, and shoot ANYONE (non essential, shooting essential characters... doesn't work right). shooting the result of the FEV infection is always fun too.
This mod should be considered a cheat weapon, as it kills via a script.
P.S. i know there are problems with the dead supermutants if their scale has been modded, working on a fix.
