About the Game

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.
