The Deep Sea — 3000 m
19 SEK — one-time purchaseYou wake alone in the submarine Leviathan, 3000 meters below the surface — the crew is gone, oxygen is running low, and every correct answer brings you closer to the surface. From the ocean's zones and the crew's logbook to sonar pings, the undersea chart and the mystery of their disappearance, you must read instrument panels, interpret animal signs and solve the final codes of ascent before oxygen — or the depths — take you.
