From publisher blurb:
It's the 1920s and earthlings have developed space travel. Nefarious space gangsters strive to steal their piece of the intergalactic pie. Stalwart space cops seek to bring them to justice. And it all happens in high-flying, pulp action among the stars. You are one of these space cops or rocket robbers...and you have super-powers!
This is a supplement for the BAMFsie Award-Winning CAPERS RPG. It provides a plethora of new character options, GM tools, and an alternative 1920s setting filled with pulp, sci-fi action and adventure.
