Strange aliens both friendly and fearsome fill this tome of creatures designed for use with the Starfinder Roleplaying Game! From the gravity-manipulating frujais and planet-killing novaspawn to space goblins and security robots, the creatures in this codex will challenge adventurers no matter what strange worlds they're exploring. What's more, player rules for a host of creatures let players not just fight aliens, but be them! The pocket edition presents the same contents in a smaller sized softcover for a lower price and better portability.
