As far as I know NoFix came up with the idea. I might have a copy around, but iirc, it was just a scripted map.
I miss NoFix
the wayback link to the fallout mod (which is different from the Fallout.zip we can download off of exiled) does seem to be the original idea. i tried to reach alex to see if he would consider releasing his circa 2000 version but i couldn't find a working email.
it would be an interesting historical tidbit if nofix was in the equilibrium dev team.
i took the nofix 1.40 knockout mod and recoded the 1.40 isms so that the mod would run on a 1.11 server.
