I’m running Slipstream, a Savage Worlds pulp scifi setting along the lines of Flash Gorden, Buck Rogers and Forbidden Planet. Would love to see a set that runs along those types of sounds. Ray guns, rocket ships along with dramatic and mysterious background themes.
Try out (in the Sci-Fi Player), Climactic Space Battle, Contest of Champions, Farside City, Freedom City 2525, Ghroth, Grue Invasion, Time Tunnel, Wormhole, Spaceship Battle, Lightsword Battle, Shipboard, Space Fight, Starfinder - Handheld Weapons, Alien Planet, and then Preserver Artifacts for several different background themes. Evil Android, Cyborg Dragon, and Alien from Alien also has some great foes for your heroes to fight.
