Have they put out GammaWorld for d20 yet?

[Jer]

Just wondering if they did, and if it is any good.

People on this thread have already pointed out the Sword and Sorcery Gamma World release and the Omega World Polyhedron issue. Of those, Omega World is defnitely a good value for the money. Very playable and very much in the "feel" of Gamma World, though it may not be as useful for a long-running campaign. S&S's Gamma World is a bit more iffy, but if you can find used copies somewhere some of the books are worthwhile (especially the "monster manual" Mutants and Machines).

Something that hasn't come up here yet is the "d20 Apocalypse" supplement for d20 Modern. I personally think that this is one of the best d20 Modern supplements Wizards put out and it's full of good stuff to add to a Gamma World campaign. It would mesh fairly well as an expansion to the Omega World setting and with some tweaks works okay for S&S's Gamma World. Be warned, though, not everything in the book is going to be useful for a Gamma World game since it also covers "magical" apocalypse scenarios.

One thing that neither system does explicitly is handle the mutant animal aspect of old-school Gamma World. Omega World tries by having a handful of races that represent mutated animals (one for insects, one for mammals, and one for lizards IIRC). d20 Apocalypse recommends using the "Moreau" races from the d20 Modern book to represent mutant animals. Neither of those solutions feel as satisfying to me as breaking out the mutant animal charts from 4th edition Gamma World and going to town with them, but YMMV.

Yup, I'll share some of the stat conversions, once I'm finished. Just so...

Gallus Gallus 5/13s are six foot tall pot-bellied humanoid chickens, that originated as the failed genetic experiment of an experimental automated chicken breeding and meat processing plant. They have only one eye, but also three-fingered hands and color-shifting feathers. They are highly intelligent, if a bit clumsy, and have a natural resistance to mental and psychic domination.

Psychic Shield
You can shield your mind from psychic influences. When you are the target of a power granting a Will saving throw, make a Psychic Shield check. The attacker must make a power check using the attacking power. If your check result is higher, the power fails. If the attacker’s result is higher, the power affects you normally, but you still get your normal saving throw.

You may choose to voluntarily lower your Psychic Shield as a free action, and can raise it again as a free action. Otherwise, your shield is always active, even if you are unconscious or sleeping.

Shields and Maintained Powers: Once a power has overcome your Psychic Shield, it continues to affect you as long as the user maintains it. You’re still entitled to your normal saving throws, if any, but your shield no longer protects you from that power. Once the attacker needs to make a new power check, however, your shield comes into play again and must be overcome again. For powers requiring mental contact, so long as the other adept remains in mental contact with you (inside your shield), he can use those powers freely without worrying about your shield.

Overcoming Psychic Shields: An attacker can choose to suffer a fatigue result to gain a +5 bonus to overcome your Psychic Shield. This is in addition to any fatigue caused by the power used against you. If you also choose to suffer a fatigue result, the attacker loses the bonus and must roll normally to overcome your shield. This process takes no actual time; it happens as part of the check to overcome the Psychic Shield. An attacker trying to avoid notice cannot use this option, since it makes it immediately apparent that you are under psychic attack.

Time: Using Psychic Shield as a defense is a reaction; raising or lowering your shield is a free action.
