Danger In The Deep

Danger in the Deep is a collaborative escape room game set aboard a nuclear submarine. When the Retiarius submerges unexpectedly and its warheads begin to prime, your mission to track down enemy spy PROTEUS becomes a race against time — you'll need sharp observation, lateral thinking, and solid teamwork to prevent disaster.

Work through 14 interlinked puzzles spread across the engine room, crew's quarters, mess, and control room. Puzzle books, cards, and physical components — including a submarine blueprint and a UV torch — reveal hidden information as you piece together what's really going on. A tiered hints system keeps things moving if you get stuck, and the game works just as well solo as it does with a full crew.
