The year is 19XX. As the country’s most successful secret agent, you are hunting for the mysterious spy PROTEUS aboard the docked nuclear submarine Retiarius. But the mission takes a dangerous turn when the submarine suddenly dives… and its warheads begin to load for launch!

Danger in the Deep is a cooperative escape room style game where players must navigate through the engine room, crew quarters, mess hall, and control room to solve 14 interactive puzzles. Collect clues, unmask PROTEUS, and disarm the weapons before it’s too late! The game includes puzzle books, cards, secret components, a blueprint, and a working UV flashlight (batteries included).

The game features a multi-level hint system, allowing players of all levels to progress through the story. It can also be played solo. For a reusable experience, printable components are available online.
