Gateways to Terror

Gateways to Terror contains three short-play scenarios, ideal for beginning and experienced players and Keepers alike. Originally, all three—The Necropolis, What's in the Cellar? and The Dead Boarder–were designed as demonstration games to give a taste of the game's core motifs—mystery, investigation, and horror—for those with limited time. The scenarios can be played in as little as one hour but can be expanded for slightly longer play, and each comes with four ready-made investigators so you can jump right into the action! Each scenario includes hints and tips for Keepers new and old, suggestions for additional investigators for larger groups, and a summary of the key rules needed to play.
