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): 0.29/day in the week to Jul 21 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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
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.

По сути аналог Dome Keeper, тоже ходим по шахтам и копаем пока не выйдет время, затем садимся в мех и убиваем волны и так по кругу. Сама идея данных игр классная, но здесь исполнение такое себе, очень скучненько, не интересно/ Контента очень мало, даже с учётом, что есть обязательная мета, проходится игра буквально с двух попыток за час. Ну и 400 рублей за час геймплея так себе, но в целом сама игра нормальная и даже в моменте интересная

Атмосферна грінділка, в підводному світі. Має місце, для фанатів схожого геймплея. Зірок з неба не хватає. Розвиток поступовий, геймченж білд присутній. Реграбельність - 50/50. На декілька вільних вечорів, або доки не набридне.
Frequently obnoxious level design. There is no reason I need to have my progress entirely blocked because I haven't ground out enough speed perks.
惜しい・・・滅茶苦茶惜しいと思う。 ゲーム性は面白いけど武器や装備のバランスが残念すぎる。 武器は最初のマシンガンが一番強いし、それ以外は逆に弱すぎる。 育てれば強いんだろうけどこれ育てるくらいならゲーム中に手に入る武器育てた方が強いし、そもそもそんな悠長でもないゲームバランス。 他もシールドとか掘削機とか、正直マルチ云々言う前に整えるべきバランスは沢山あると思う。 せめてこのヴァンサバライクのメイン処であるはずの掘削がもっとパワーアップできるのであればマシンガン以外の弱武器を使う意味も出るのだろうけども・・・ 翻訳は翻訳機にいれただけなのだろうけどオラついたり敬語だったり、でも翻訳してくれるだけありがたいよねって私は思います。
Ta longe de ser um masterpiece dos roguelikes e a historia parece fraca, mas é divertido pra passar o tempo
вдохговленная wallworld на пару вечерков, быстро приелась легкие ачивки для 100% игры
Addictive little gem :)
I want to like this game but it is far, far, too difficult. Needs an easier difficulty setting.
Класний рогалік, можливість прокачки між ранами дає стимул починати заново. Приємна графіка, гарний звук, різноманітні моби, рекомендую. Кооп версія не зайшла поки, чекатиму на оновлення
