From the back of the book-
"Enter a post-apocalyptic nuclear wasteland filled with mutants, ruins and radiation! You can take the role of an android, mutant human, mutant animal, pure human, and even a mutant plant! Seek wealth and ancient technological artifacts. Enter vast underground complexes and avoid killer robots!"
Mutant Future is a Labyrinth Lord compatible, standalone RPG that seeks to recapture the feel of the classic post-apocalyptic "sci-fantasy" games of the late 1970s and early 1980s, such as TSR's Gamma World. Unlike Labyrinth Lord, however, Mutant Future is not a "retro-clone" that duplicates the original games' rules, but rather a new game that attempts to remain true to the spirit of the earlier systems.
