Gamma World’s evocative cover art of 4 explorers crossing alien terrain, spotting the jagged remnants of ruined skyscrapers of an Ancient city. From the beginning, the original Gamma World grabs you, and doesn’t let go.

The Rulebook

Gamma World 1st rulebook

Cover and title page art by the legendary David A. Trampier.

The original, detailed, cause of the apocalypse would only be found in the 1st edition.

The rules immediately set the game apart from the typical fantasy RPGs of the time: Mutations and Technology. And these areas are richly detailed. Though characters begin play without technology, the unspoken assumption is that the PCs would quickly acquire ancient artifacts.

Though Humanoids and Mutated Animals start out with the physical and mental powers to survive in a dangerous environment, Pure Strain Humans can only rely on anemic primitive weapons, and the promise of great things in the future if they survive, since they are most able to utilize ancient artifacts. (This reminds me of AD&D magic users: Start out weak, but amass power as they gain levels.)


The rules and background, even if a bit thin by modern standards, are enough to play. The setting is so rich and exotic, it would take a pretty dull referee to not be able to use this set as a launchboard for their own imagination.

Cryptic Alliances are an important part of Gamma World, factions based on characteristics or common beliefs. They can be allies, adversaries, or something in between.
Discovering an ancient piece of tech is only the beginning. Discerning the artifact’s function uses flow charts that are a minigame unto themselves.

The Map

Gamma World 1e 3p map

The large hex map in the original GW set, with its not-quite-familiar continental outlines, has never been matched in its simple beauty in any of the later editions of Gamma World. Depicting oceans, lakes, mountains, and ancient cities (some underwater!) – yet no labels – the map practically begs the referee to puzzle out what the cities are, and to fill in their own details.

A section of the map from my personal set. I labelled the cities decades ago.

Dragon Magazine, issue 25 (May 1979), had an article by GW creator James Ward: A Part of Gamma World Revisited. There is a key to the cities on the big map, plus notes on the geographical locations and leadership of the Cryptic Alliances.
