Top Secret S.I. Book Bundle

Enter the world of Cold War–era espionage with this classic Top Secret S.I. roleplaying game bundle, featuring three essential books from TSR’s iconic spy RPG line.

Top Secret S.I. delivers a grounded, realistic take on intelligence operations, focusing on tradecraft, surveillance, covert missions, and global intrigue. Inspired by real-world spy agencies and techno-thriller fiction, the game emphasizes planning, equipment, and consequences over cinematic fantasy.

This bundle includes:

• Player’s Guide – Core rules, character creation, skills, equipment basics, and player-facing mechanics

• Administrator’s Guide – Campaign and mission design, adversaries, intelligence organizations, and tools for running covert operations

• G4 File: Guns, Gadgets, and Gear – An extensive expansion packed with espionage weapons, surveillance tools, vehicles, and advanced equipment, ideal for deepening realism and tactical options

Together, these three books form a near-complete Top Secret S.I. experience, making this bundle perfect for collectors, retro RPG enthusiasts, or groups looking to explore a classic, non-fantasy tabletop RPG rooted in realism and tension.

Condition: Pre-owned. Books show normal shelf wear consistent with age but are complete and fully usable.
