From the release:
Shape changing is a fascination crossing time, culture, and genre: Greek gods and mythic Indian monsters, vampires, were-creatures, spirit and shadow beings all captivate and intrigue with their metamorphoses. Shapeshifting in Mutant Future is no different; one of the most interesting and useful powers, it provides a player character with new abilities and opportunities a single body cannot. And if a Mutant Lord, it gives you two monsters for the price of one!
Wisdom from the Wastelands is dedicated to providing useful information, game content, and ideas to players of modern, science fiction, and post-apocalyptic table-top and role-playing games in general and to fans of Goblinoid Games’ Mutant Future RPG in particular. The material it contains are compatible with it and any others that use the "Basic" system introduced in the most popular role-playing games of the early 1970s and are easily adaptable to many other games (especially successor systems, to include those covered by the Open Game License).
