Starfinder Second Edition Playtest Rulebook

Publisher's blurb:

The Starfinder Playtest Rulebook brings Starfinder into a new age of compatibility, as Starfinder switches to using the same rules engine that powers the popular Second Edition of the Pathfinder Roleplaying Game. Inside this playtest for the new edition, you’ll find six new classes, 10 ancestries, new skills, new feats, futuristic equipment including augmentations and upgrades, new science-fantasy spells, and more! You can directly shape the future of Starfinder by participating in a fun and rigorous playtest using one of several playtest adventures released throughout the playest period, or by trying out the new rules in your own games.
