Skirmisher Publishing has released “Mutation Artifacts,” a mini-sourcebook that describes two-dozen devices created both by those who lived before the cataclysm and by wasteland dwellers that modify mutations and which includes four new mutations. 

Contents of this publication are stat’ed for a “Basic” version of the OGL/d20 system and is compatible with any games that use it, especially ones like the Mutant Future retroclone of Gamma World, and easily adaptable for many others. It is available by itself and as part of a 51% off Mutant Future Bundle.
