Submeris

Submeris is a deep-sea mining adventure set beneath a remote, mysterious island. You dig, upgrade your equipment and descend through underwater tunnels in search of treasure, while managing oxygen and radiation and avoiding collapsing passages and deadly sharks.

Dig and descend

You begin with a simple shovel, then improve your gear to dig faster and break stronger materials. Use dynamite and other tools to clear obstacles and open paths, a detector to find buried treasure and hidden cash, and an upgraded light source to see through dark tunnels. Expanding your inventory lets you carry more loot, while greater oxygen capacity and radiation resistance help you dive longer and deeper.

The game has a depth-based leveling and progression system. You can sell valuable minerals, find rare treasures, unlock secret rooms and loot hidden chests. Deeper layers hold precious minerals, legendary treasures and greater risks, including radiation zones with time pressure and unstable tunnels that may collapse.

Hazards below

Sharks guard the final treasure and threaten divers in deep treasure zones. Survival also depends on managing oxygen and radiation as you explore dark underwater environments, where dynamic lighting shapes what you can see.
