The Center Space 2nd Edition

A science-fantasy roleplaying game set on Earth after a 300-year alien occupation. Survivors and other evolved beings contend with monstrous creations, rival factions, advanced technology, psychic powers, and the mysterious energies of the Center Space while the galaxy remains in chaos. The d20-based rules include ten new races, nine futuristic classes, prestige classes, alternative psionics and magic systems, over 200 psychic and channeling powers, and a Spirit system for attempting extraordinary actions. Players can use new feats, mutations, cybernetics, weaknesses, and living alien technology, with rules for vehicle and starship combat. This edition revises and simplifies the classes, skills, feats, and Spirit system, with creature and adventuring material provided separately.
