From the introduction:
Saviors is a roleplaying game. It uses the FUDGE rules, which are available for free in the internet. Saviors is a science fiction game about energysword-wielding heroes facing countless combatdroids in a postapocalyptic Earth. It's fun and loose for the most part.
The Saviors game is presented in four major HTML sections: Main (introduction), World (setting), Rules, and Stories (fiction). For the most part, the rules are a straightforward implementation of Fudge.
