Mars in the 25th Century

From the back of the book: "Mars in the 25th Century is the first product in a line of accessories for the XXVc science fiction role-playing game. It describes all aspects of the planet's civilization and culture - information that referees can use to create adventures on the Red Planet. Mars is a place of beauty, tainted by an undercurrent of terror. It is a world that combines the best features of high technology with the worst aspects of oppression and slavery. It is a planet where an enterprising person can make a fortune... or lose his life. For players of the XXVc game, the opportunities for adventure on Mars are limitless - and danger lurks around every corner."
