Encounters: Sci-Fi Scenarios

This science-fiction role-playing supplement provides referees with guidance for building consistent campaign settings, creating NPCs with believable motives, and making character actions matter. Tables generate interstellar travel mishaps, location-based encounters, mission complications, and events arising from the players’ choices. Entries range from brief prompts to detailed scenarios with twists, including situations for characters separated from the group. The book also includes new starship designs and background material for the Era Ten setting, while remaining adaptable to other science-fiction RPGs. It uses two eight-sided dice and a standard deck of playing cards, not included.
