This 264-page rulebook contains everything Game Masters require to plan out and organize galactic tales of adventure and campaigns. The book includes guidelines for creating encounters, determining success or failure of in-game actions, and handing out rewards to players as well as other advice for running game sessions. It also has rules subsystems that cover an array of game situations: rules for chases, cinematic starship combat, research, hacking infiltration, and more.
This book also contains a guide to the Pact Worlds as well as the expansive galaxy, which highlights important areas for exploration. The Starfinder GM Core book is also compatible with Pathfinder 2E RPG and will retail for $69.99.
Paizo, Inc. will also release Starfinder Player Core, a new RPG core rulebook for Starfinder 2E, into retail on July 31, 2025 (see "'Starfinder Player Core'").
