About
Fight endless waves of monsters, protect your Mech Spider, and mine resources in Ocean Keeper, a survival co-op roguelike. Play as one of four miners, upgrade your gear and Mech, and explore underwater dungeons. Face the ocean’s dangers and do whatever it takes to stay alive.

Team up with your friends and climb into the Mech Spider to kill thousands of monsters. Work as a team to protect your Mech – if it goes down, your crew will be defenseless against hordes of creatures.

Take a rest from endless battles and explore the caves in search of valuable resources and rare artifacts. But don’t get too comfortable – your team has just one minute to mine, upgrade your gear, and get ready for the next wave. If you are brave enough, you might find something truly powerful… just in time to face the bosses.

Mine resources from the ocean depths to unlock and upgrade powerful gear. Choose from 9 unique weapons – each with its own range, strengths, and playstyle. Don’t forget to coordinate with your team and plan your loadout beforehand: strategic positioning is key to protecting your Mech and surviving the endless waves.

In Ocean Keeper, no two waves are ever the same. Each brings new challenges, enemies, and opportunities for your team to adapt, strategize, and survive various underwater adventures. Upgrade your gear differently every time, uncover rare relics, and battle frightening bosses – you will never experience any run twice.
So gear up, dive deep, and may your Mech legs never rust.
Good luck, survival miners – the ocean is waiting.

We were playing as two My friend stepped into a trap and the door closed. To free him someone had to press a button. I went in to help and we both got stuck had to restart the session. This shouldn’t happen but it was very funny
I dig hole. I find shiny rock. I upgrade big robot spider. I die. I repeat. Life is good
Add mech customization and more dynamic environments. Overall it’s pretty cool
[h1]Ocean Keeper Co-op - рекомендую[/h1] По суті це Ocean Keeper Dome Survival, але вчотирьох. Копаєш ресурси між хвилями, захищаєш базу, апгрейдишся, повторюєш. Затягує особливо коли є з ким грати. З [b]плюсів[/b] - це атмосфера підводних печер зроблена зі смаком. Але є [b]нюанси[/b]. Підтримка геймпада зламана: Xbox-контролер відрубується, а підказки на екрані завжди клавіатурні. Загалом за таку ціну дуже годна гра - рекомендую грати у компанії друзів.
ni menu d'amélioration ni vraiment de roguelike, on casses des minerais sans même savoir à quoi cela sert a par des points pour des "améliorations" accès à une seule arme pour l'entièreté du niveau, des bots où on ne peut pas choisir leurs armes, trop de dégâts pour trop peu de soin, bref d'un ennuie mortel.
10 stupid bots out of 10. Much better with friends
1.Simple 2.Sometimes boring 3.Overall not bad 4. Don’t go into the portal at the start
Why does my friend always want to dig, and I’m the one carrying?
the drill is the most effective thing in the game
