Gamma World is a science fantasy role-playing game, originally designed by James M. Ward and Gary Jaquet, and first published by TSR in 1978.

Gamma World takes place in the mid-25th century, more than a century after a second nuclear war had destroyed human civilization.

The war that destroyed civilization in Gamma World is only vaguely described in most editions of the game, and what details are provided change from version to version.

In many editions of the game technology is at best quasi-medieval ( in the first edition, the crossbow is described as " the ultimate weapon " for most Gamma World societies ).

Some, such as the 2010 edition, feature advanced, but rare, technology that is risky to use due to the average Gamma World character not knowing how to properly operate such devices.

The post-apocalyptic inhabitants of Earth now refer to their planet as " Gamma World " ( or " Gamma Terra " in later editions ).

Gamma World is a chaotic, dangerous environment that little resembles pre-apocalyptic Earth.

( Random tables of such improbable mutations are a hallmark of every edition of Gamma World.

Gamma World player characters include unmutated humans ( referred to as " Pure Strain Humans " in most editions ), mutated humans, sentient animals or plants, and androids.

A recurrent source of conflict on Gamma World is the rivalry among the " Cryptic Alliances ", semi-secret societies whose ideological agendas — usually verging on monomania — often bring them into conflict with the rest of the Gamma World.

Throughout the game's many editions, Gamma World has almost always remained strongly influenced by Dungeons & Dragons and other role-playing games of the time.

Four of those abilities ( Charisma, Constitution, Dexterity and Intelligence ) have the same name and functions in both games, and the Physical Strength and Mental Strength attributes in Gamma World closely parallel Strength and Wisdom in D & D.

All versions of Gamma World eschew a realistic portrayal of genetic mutation, instead giving characters fantastic abilities ( often resembling comic book superpowers ) such as electrical generation, infravision, quills, sonic attacks, multiple limbs, dual brains, total body carapaces, precognition, planar travel, weather manipulation, telepathy, and " life leeching ".

Characters in all versions of Gamma World earn experience points during their adventures, which cause the character's Rank ( in some editions, Level ) to increase.

Unlike D & D, however, the first two editions of Gamma World do not use a concept of character class, and increases in Rank do not affect the character's skills or combat abilities.

The game mechanics used for resolving character actions, on the other hand, greatly varied between Gamma World editions.

( The ACT concept is drawn from the Marvel Super Heroes game published by TSR shortly before development of Gamma World < nowiki >'</ nowiki > s third edition.

Gamma World < nowiki >'</ nowiki > s fourth edition abandoned the Action Control Table in favor of mechanics derived from the Advanced Dungeons & Dragons 2nd Edition rules, although some mechanics presage Alternity and the 3rd edition D & D rules.

The fifth and sixth versions of Gamma World take the game's tendency of mimicking other games to its logical end, adopting the rules systems of other games wholesale: The fifth edition of the game uses the Alternity rules, while the sixth edition uses the d20 Modern rules.

Both of those systems, not coincidentally, use game mechanics inspired by D & D, giving Gamma World characters six ability scores, and measuring character development through increases in character class level.

Despite these differences, it is possible to use characters and monsters from a D & D game in Gamma World and vice versa.
