Our take on Ocean Keeper: Dome Survival

The defining structure is the repeated shift between drilling underwater caves for upgrade resources and defending against the next monster assault, with progression connecting both activities.

What is Ocean Keeper: Dome Survival?

Play as a miner whose spaceship crashes on a planet inhabited by underwater monsters.

Explore caves and biomes, collect resources and artifacts, then spend the time between attacks upgrading the diver, Mech Spider, weapons, and skills. Build automatic turrets and deploy drones to gather loot while preparing for the next wave. The game alternates between mining expeditions and top-down combat against hordes, sea creatures, and bosses such as a giant crab and flying mouse. Locations include abandoned science-fiction laboratories and artifact mines, with remains of a lost civilization to discover. Each session reveals different secrets, while meta upgrades and distinct mech types provide progression across runs.
