Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0/day in the week to Jul 20 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
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.

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.

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
とても面白いゲームでした。やりこみ要素があればまたやろうと思います。楽しかったです。
I dig hole. I find shiny rock. I upgrade big robot spider. I die. I repeat. Life is good
하지마세요..
It scratches that specific itch in my brain. The loop of mining -> upgrading -> defending is super satisfying. Great game to zone out to while listening to a podcast
Can't really recommend... there are many UI bugs, no tutorial and it feels like a flash game from the 2000s. Not sure of what is going on at all.
Early access vibes, yes. But the core loop is ok
