I'm Incorporating Pathfinder

Starfinder is compatible with the second edition of the Pathfinder Roleplaying Game ! Chapter 5 provides guidance for incorporating material from Pathfinder into Starfinder—or vice versa. Anachronistic Adventures, Archaic Adventures, and Timeshifted Adventures describe different ways to mix the games and settings, such as by pulling characters from Pathfinder into Starfinder, running Starfinder characters on a low-tech world, or running a campaign about time travel. Ancient Foes and Ancient Gear provide advice for using Pathfinder creatures and equipment in Starfinder games.
