The Transformers Expanded Edition: A Role Playing Game for FUDGE

From the introduction:

Many millions of years ago, on the planet Cybertron, life existed, but not life as we know it today. Intelligent robots that could think and feel inhabited the cities. They were called Autobots and Decepticons. But the brutal Decepticons were driven by a single goal, total domination. They set out to destroy the peace loving Autobots. And a war between the forces of good and evil raged across Cybertron. Devastating all in its path, draining the planet's once rich sources of energy. The Autobots, on the verge of extinction, battled valiantly to survive.
