Mutant Chronicles: The Techno-Fantasy Roleplaying Game - 1st Edition (1993)

From the back of the book:

It all began in the darkness of the void.

We freed ourselves from the hell we had
created on Earth, but freedom had a price.

The weak and the poor fell victim to the
Corporations, who rule the solar system.

Driven by their greed, the Corporations laid
claim to the tenth planet and woke the sleeping
beast, may its name be forever despised.

Thus did the Dark Legion descend on us,
howling for our death and destruction.

Now is the time to conquer our fear and stand
up against the tidal wave of the Dark Symmetry.

Now is the time for heroes.
