“Oscar North is one of the rare “living” Ancients, one of a handful of scientists who became mutated […] just before the Shadow Years. […] Of all the beings now living in Gamma World, the Ancients are the most powerful by right of their knowledge, their access to hidden caches of high-tech devices, their mutational powers, and their centuries old influence on societies.”
-GW9 Delta Fragment

Better known as Nort and Scar, this Ancient is split into two separate characters: One ostensibly human, the other a huge mutated wolverine.

Gamma World Rules Supplement and Project Omega
Added March 5, 2020
When Gamma World 3rd Edition was released (1986), it was ambitious in its scale: A completely new rules system, and a unified campaign arc stretching out over several modules.
In Dragon Magazine, issue 115 (Nov 1986), an ad – left side photo – announced the Gamma World Rules Supplement – right side photo. In its 16 pages, it would have errata correcting the rules. But the majority of the pages were given over to Robots, Equipment, Skills, and plenty more.
The Dragon ad invites players to mail into TSR for their free booklet. The Supplement would be added to later printings of the box set.

Sadly, the final module mentioned in both the ad and the Supplement – Project Omega – never saw print. I’ve had a fan-produced version available for free download on my site for many years. It’s quite good.

Sadly the artwork of Nort and Scar do not seem to be available on Mr. Parkinson’s website as prints. I have always loved the art of 3rd edition.
TSR typically bought perpetual rights to their art. Probably the situation here, where Parkinson doesn’t have the rights to his own art.
