These are the general rules for Starfinder Society Playtests. See each playtest announcement for any rules specific to that playtest.
Playtest Characters
Players can create characters using options from any published playtest material. These characters are treated as a normal Starfinder Society character and must otherwise follow all Character Creation rules.
Characters can continue using playtest rules even after the conclusion of the playtest period. Once the final version of a previously-playtested class is published, any characters using the playtest version must rebuild to use the new version of the class before their next game.
GM Opt In
Because playtests use additional rules that some GMs might not be comfortable with, each GM must opt-in for playtest characters to be used at their tables. Please consult your GM prior to the game!
