In a change of pace for Catalyst Game Labs, the company’s latest RPG, Cosmic Patrol, is a small book heavily influenced by the indie scene. The game draws players in to a retro-styled science fiction setting filled with rocket ships, atomic power, ray guns, and dangerous aliens. But the game also asks the players to share in development of the setting and story, using what Catalyst describes as improv-style play. That is, play is divided in to scenes, during which the players take turns narrating the actions of their characters using cues from their backgrounds.

Cosmic Patrol is available right now in PDF form for $4.99. Or the PDF is free with a preorder of the print version.
