You play as a miner stranded after a spaceship crash on a planet teeming with underwater monsters. Explore the ocean floor and caves while searching for resources, artifacts, and traces of a lost civilization.
Runs alternate between timed mining trips and wave-based defense. Dig through caves to gather materials, then return to your mech to fight attacking creatures and survive until the next opportunity to explore.
Spend resources on weapons and equipment for the diver and mech, and unlock permanent upgrades between runs. Story objectives and discoveries provide goals as you tackle increasingly difficult encounters.
Players who enjoy the game often praise its unusual mix of timed mining and mech combat, along with the underwater atmosphere and satisfying resource-gathering loop. Some also like making gradual upgrades and tackling short runs. Others find the cycle repetitive, the progression or weapon balance shallow, and the story and overall content brief; reports of bugs and technical problems also appear in the reviews.
Welcome to Ocean Keeper, a mining roguelike shooter with a top-down view. Play as a Miner whose spaceship has crashed on a planet, filled with underwater monsters. Find resources and artifacts for purchasing valuable upgrades.
Use the time between each attack to power up your diver, mech, weapon or explore a new dungeon. Build automatic turrets, use drones to collect loot and improve your skills to increase your chances of survival. If you've ever wondered what would happen if you mixed Dome Keeper, Wall World and Vampire Survivors together, here's the answer!

Dozens of weapons, upgrades, and monsters are waiting for you. And all this in the subnautica style, along with sea monsters who are hunting you. The world here is dangerous,
and keeps in unknown threats.

The underwater world of Ocean Keeper consists of many biomes. You will have to travel through the locations and find the remains of a lost civilization. Discover mysterious locations, from abandoned sci-fi laboratories to mines with artifacts.

Drill caves in search of different resources to upgrade your equipment, weapons and Mech Spider. It's worth saying that the local fauna didn't like the fact that you want to mine their sources! So don't forget to exit the dungeons, and switch to a dynamic combat mode.

Ocean Keeper is ready to surprise you by massive battles with unique bosses! From a giant crab to the flying mouse, each battle will be a true challenge. We won’t reveal all the cards — there are many more. The other question is, will you have the strength to defeat them?

Forget about monotony - each new game session will open new secrets of the underwater world, and battles with sea monsters will become harder. You can use various meta upgrades and unique types of Mechs to bravely fight with every wave of monsters.
