Players create a character defined by six attributes: Strength, Agility, Constitution, Charisma, Intelligence and Education.

[1] The game is set 450 years in the future, in the post-apocalyptic world of Mark Schultz's underground comic book series Xenozoic Tales (ISBN 1-55878-073-4) when creatures from every era of history roam the Earth.

[3] In the September 1992 edition of Dragon (Issue 185), Rick Swan liked the simple and easy, laid-back approach of most of the rules.

He was therefore surprised at the complexity of the combat rules, calling them "gratingly out of synch with the user-friendly approach of the rest of the game."

Fans of the comic book should get a kick out of the informative sourcebook material and Mark Schultz’s exquisite illustrations.
