From the back of the book:
- Characters encounter altered ones and living metal while searching the hostile wilderness for hidden secrets of the ancients!
- They try to penetrate the blue man's renegade Iron Society enclave to uncover the mystery of the Yorkum Turkel.
- This adventure for the new 4th Edition GAMMA WORLD game is designed for three to six characters of 1st to 3rd level.
- Mutant Master is an excellent tool for beginning a new GAMMA WORLD campaign, either based in Ascension in Gamma Terra, or adapted into a GM's personally designed world.
- It is recommended that the character group have at least one Altered Human.
Note: Front cover incorrectly says "Game Rules" under the GAMMA WORLD logo, should say "Adventure."
