About the Game

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.

Ocean Keeper taught me I'm terrible at: ✓ Time management ✓ Resource prioritization ✓ Combat positioning ✓ Learning from mistakes ✓ Stopping after "one more run" Perfect game 👍
Day 1: This game is pretty chill Day 3: WHY ARE THERE SO MANY MONSTERS Day 7: I AM THE MONSTER NOW Day 14: We don't talk about the flying mouse boss
⚠️ WARNING ⚠️ Side effects include: - Thalassophobia - Compulsive mining disorder - Inability to see "Game Over" as final - Dreams about mech spiders - Crab-related PTSD Play responsibly (I didn't)
Went in expecting casual mining game. Got souls-like difficulty with cute graphics. Died more than in Dark Souls. Raged more than in Cuphead. Loved every second. Ocean Keeper doesn't hold your hand. It drowns you with it. 12/10 would suffocate again
The main reason I've decided to write this review is not because Ocean Keeper: Dome Survival is a bad game (and, trust me, IT IS) - it's actually because they are now launching a new game. More on that in the final paragraph. I've finished the story and got the 100% in about 5 hours so I believe I have enough material to say what I'm about to say. If you're wondering why the 100% in a game I hated - masochistic completionism and achievement hunting. If I would have to sum up my Ocean Keeper experience in one sentence, it would be - more of the same but in different colors, until you are bored to death. Game feels boring, unoriginal, incomplete, hastily put together, and all that while trying to copy the greats like Wall World and Dome Keeper. If they had just one ounce of inspiration and talent Alawar and Bippinbits had, this might not have been such a disaster. Runs are long (there were runs where I died on purpose), meaningless, with grindy upgrades that are just numbers slightl...
Showed Ocean Keeper to my dad Dad: "Why is your robot so slow?" Me: "You need to upgrade it" Dad: "With what money?" Me: "You mine for it" Dad: "But the enemies-" Me: "Yes" Dad gets it now
Ocean Keeper meta progression: Hour 1-10: Everything kills you Hour 10-30: Most things kill you Hour 30-50: Some things kill you Hour 50+: You kill everything Hour 100+: Everything kills you again (higher difficulty) The cycle continues
Ocean Keeper drinking game: - Shot when you die to worms - Shot when you forget resources in cave - Shot when boss one-shots you Update: Don't play this drinking game
this game has layers: Layer 1: Cute mining game Layer 2: Oh god why so many enemies Layer 3: Strategic depth emerges Layer 4: I HAVE BECOME DEATH, DESTROYER OF CRABS Layer 5: The worms... THE WORMS
