How to play Deep Sea Adventure
Read the wreck
Follow the navigation arrow toward the captain’s log. Descend to its marked depth and swim through the open side of the wreck. Approach a tablet and press Examine or E.
Explore the ruins
Recover clues at the drowned courtyard and silent watcher. Keep clear of jellyfish and their tentacles. Hold your course through currents. The gateway opens between its two stone piers.
Bring the truth home
Use your three clues to decode the submerged archive beyond the gateway. Return to the surface buoy with the archive. The navigation changes to guide your journey home.
Space / Ascend rises; C / Descend dives. Holding Boost swims faster but uses more oxygen. Two labeled spare-air caches each replenish 115 seconds once per dive. The starting air supply is 360 seconds. Practice removes oxygen and condition limits and does not set a best score.
Swimming, breathing, bubbles, light switches, clue recovery, stone contact, jellyfish stings, air refills, currents, warnings, archive symbols, failure and completion have distinct original synthesized sounds. Sound and Volume govern all effects and underwater ambience. Audio starts after Begin dive. Pausing or leaving the game freezes oxygen and movement. Detail: Low reduces shadow and particle costs.
This real-time browser game uses a visible human rig fitted with scuba equipment, textured masonry and wreck geometry, moving fish, particles, caustics and a hand-held spotlight. It follows the concept’s underwater theme; the concept image is not an actual gameplay screenshot or a promise of identical photographic detail. Requires WebGL 2. More Arcade Games →
