HOSTILE Technical Manual
A technical reference for a gritty, retro-futuristic science-fiction setting, this book examines the workings and history of hyperdrives, artificial gravity, androids, fusion power, hypersleep chambers, communications, computers, and other forms of “retrotech.” Essays and practical explanations support roleplaying with a consistent engineering logic. The material helps resolve in-game questions about contacting ships while in hyperspace, locating anti-gravity systems, sabotaging infrastructure, and understanding how the setting’s technology operates. It is designed for use with Cepheus Engine and other Classic 2D6-based science-fiction roleplaying games.
