Gamma World - 4th & later editions

Editions: 4th ~ 5th (Alternity) ~ 6th (D20 System)


4th Edition (1992-1993)

Gamma World, 4th edition
A rainbow of flickering colors dances across the night sky. Turning, you shamble off into the jumble of cloud towers amid the glow. With an effort of willpower you float over the gaping chasm of softrock and steel. Your large, webbed feet paddle the air slowly.

Suddenly, you detect a dim mind signal. Your antennae seek its direction. Knights of Genetic Purity! Quickly you unholster your weapons, all four arms moving in smooth harmony. Tracing the cryptic symbols of the ancients on its metal skin, you awaken the sun bolt gun. If the air currents stay strong, you might make it across the chasm before the Knights arrive.

In 1992, TSR warmed up their dormant Gamma World line with the 4th edition. The rules were returned back to the
D&D style of play. Cover depicts a hardy adventurer of Gamma Terra taking aim at an Obb. These rules are just prior to the Alternity edition & the D20 version. In other words, this is the last edition of the classic game. Refined rules, all the extras (Mutated Plants, Robots, etc.). New character classes: Enforcers, espers, examiners, & scouts. A personal favorite, for it is easy to teach new players.
The color map centers on the region around Lake Mitchgloom and Lake Ire, with the major political entities being Miacholin, Yrsahl, Bonparr, and Huush. The map is loaded with intruiging adventuring spots such as the migratory path of the Rambling Woods, the Burning River and ancient ruins like the Gruesome Afbayz.

Treasures of the Ancients (GWA1)

"The Ancients are a race of mysterious humans that once revelled in the glories of technology. Suddenly, inexplicably, they were wiped out. Their tools, their vehicles, their weapons, and other devices of interest can be found in the ruins of their former cities, buried in radioactive slag, or submerged under rerouted rivers and lakes.

This accessory includes the following:
• Weapons, bombs, grenades, and other military systems, including the lethal Mark XII Blaster.

• Medical products to aid characters in their adventures, including the rare and wonderful Life Chamber.
• Dozens of robots, including the Exterminator and the Devastator -- two robotic devices that will make the most powerful mutants cringe in fear.
• An additional suit of powered armor."

Mutant Master (GWQ1)
"Secreted away in his hideout, the Mutant Master makes his plans. 'Fellow New Men!' he cries out to the crowd before him. A roar of approval rises before he can continue. 'We have bided our time, waiting for the opportunity to move forward into a new and glorious day. We have tolerated the scorn and derision of lesser races, knowing that one day, we would reign supreme!' Another roar engulfs the Mutant Master. He raises his arms for silence, his blue skin glistening in the sun. 'Today, we begin the conquest of the world!' The cheer is deafening as the New Men surge forward, ready to show their loyalty for the Mutant Master, eager to do his bidding. The world doesn’t know how much trouble it is in...

All Animals Are Equal (GWQ2)
"Three hundred years after the end of civilization, the creatures are running the zoo. Home to a bewildering array of talking, intelligent creatures, the zoo has turned into a melting pot of political intrigue, assassination, and homicide. The factions bicker and battle over territory, food, water, and power.

Here in the zoo, humans are the outsiders. But when player characters enter the scene, they are welcomed as the means of upsetting the balance of power. The Pride, the Troop, and every other faction seems to have a past wound or old humiliation to settle. See what a zoo politics can really be with All Animals Are Equal."

6th Edition: D20 System (2003-2004)

Gamma World Player's Handbook (D20)
"First off. Ignore the cover title. This was originally meant to be a Campaign book, not a PHB, and this is why it doesnt feel like a PHB book.
Secondly dont grab this book thinking its going to allow you to play a GW game straight up. There just isnt enough presented to do it propperly without A WHOLE LOTTA work on your part. This book is meant to be part of a FIVE book set. The
d20 Modern core book(D20M), The Players Hand Book(PHB), The Monster Manual(MM), Arms & Equipment(A&E), and Dungeon Masters Guide(DMG).
The third thing to consider is that this IS NOT the old Gamma World setting in any way. Dont expect much to be really familliar, which is a big change from 5 preceeding editions where there was a definite familliarity from one to the next.

What does the book give you?
You get a post apocalyptic setting wherein mankind reached the heights of technological and biological manipulation... And then proceeded to tear it all down and differing factions all vied to make dominant some vision of 'how things should be.' This is a world where new life forms and sentient beings were grown on demand, where AIs became sentient minds, and were then placed in toasters and screwdrivers, where nanotech became so prevalent the stuff all but saturates some regions. The art is all black and white and is well presented. The writing has many typoes and goofs, but nothing truely reaches out and smacks you as broken.

The book proceeds from a overview of the setting to get down to character creation. Humans are divided into the Stock Human (stadard in all ways), and the Pure Strain Human (Familliar with technology still.) Next are Mutants. Divided into several sub groups, Altered Animals (beasts hiven human form and sentience), Altered Humans (Modified people that breed true), New Men (Mutated humans), and True Mutants (A catch-all for any mutant. They also tend to gain more mutations on levelling or when severely damaged.) The last race being Synthetics. These are free thinking (more or less) robots and androids that have survived after the wars. Synthetics can upgrade themselves with special equipment.
Next is the Class system. This is the d20M system that is based around attribute ideals such as Strong, Tough, Fast, etc. This allows a more custom class creation as you move along. For the d20GW there have been some slight changes and additions.
New skills and feats are presented and occupations available to work through. With time the players can move into Advanced Classes unique to the setting. Survivor, Nanosmith, War Chief, Prophet, Leader, and Cybercologist.
A selection of equipment and vehicles are given. This section has just enough to outfit a character. But is far from complete or extensive. That will be covered in the A&E book (Out of the Vaults). There is a section covering some Synthetic upgrades at the end.

The next section delves into powers and effects and starts with Mutations. Sadly this section is very weak and does not give enough to really satisfy most fans of previous editions. The mutations though follow into the Biotech Implant and Graft section where it is explained the rules for biological gear that mimics mutations.
This is followed by the Nanotech system. This is the focus of the new setting and nanites can be used to produce a vast array of efects limited only by the users imagination, skill, and access to local and personal nanites. You define scope, power, effect, and more, then try to get the nanites to do what you want.
Cybernetics are given their own section. Bionics and cyborg attatchments are detailed.
Psionics are seperated from mutations and now potentially accessible by non-mutants. The system is both very sparse, 4 psi powers with sub-systems, and has some application flaws that can lead to potential abuse.

Next up is environ and society. First is a section detailing environment. Mountains, forest, etc.
Then the book devotes a large section to Community creation. Communities are given PC style stats, skills, feats and more and are meant to draw the players intoa more active role in the affairs of their home base as it were. This section may perplex or delight you, depending on your tastes.

The monster section covers both old edition mutants and machines, and some new ones too. Though many entries are lacking illustrations. The mutants in this section do NOT use the mutations system presented for players.

The book finishes with some conversion notes and the 4th Ed Gamma world classes converted to d20 D&D format for those wishing not to use the d20M class system.

If the changes and new system do not put you off, and you want a setting less grim than Darwins World. Then the new d20GW setting may be the thing for you and this is where you start." ...from Amazon reviewer John W.
