Welcome to the Playtest!
The Character Operations Manual Playtest for the Starfinder Roleplaying Game introduced new classes to Starfinder for the first time since the game's release in August 2017, allowing players to creature their own biohacker, vanugard, and witchwarper characters. The playtest ran from December 2018 to January, 17, 2019.
Paizo hosts a live Starfinder stream every Wednesday, where we talk about all things Starfinder—including the Character Operations Manual Playtest. Videos from the stream are archived on Paizo's YouTube channel if you miss the live broadcast.
