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): 10.44/day in the week to Aug 4 → 29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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
In a solar system cut-off from a ravaged Earth, you play as a scavenger trying to make a living in the dredges of space. Wage-slave scrapper life isn’t enough anymore, and at last you’ve pulled together the funds (plus a hefty loan) to have a go at independence.
Based in the same universe as Blue Bottle Game’s last hit NEO Scavenger, learn to manage your dysfunctional crew and ship as you fend off bankruptcy...or worse.
Every choice you make will affect the outcome of the game. In character creation, you’ll use a Career Kiosk to shape your character’s background, income, and qualifications. Use it to customise your traits and skillset, which will be essential when managing your ship, its crew, and anyone sticking their noses in your business. You’ll start out the game with enemies, ex-lovers, and acquaintances to seek out… or avoid. Just remember your early decisions will affect your options and outcomes in conversations down the line.
Build your dream ship from the ground up, using detailed, functional parts. Scavenge “pre-loved” parts in the boneyard to upgrade your ship - finding old or rare parts in the system is much cheaper than tracking down the original manufacturer. Who has time to scour the solar system? Hook up subsystems, add extra power and fuel, and be sure to replace parts which have worn out during your adventures. Parts are essential to your experience and will change how your ship feels to fly.
“I cannot change the laws of physics, Captain!” In Ostranauts you will be piloting a ship under the laws of Newtonian flight, learning to fly using in-world manuals and sheets. It will be your job to manipulate control panels, flip switches, and to resist the urge to press the big shiny red button… Every craft has a different flight feel based on thrusters, hull mass, and how you’ve customised the ship. Remember to use a light touch whilst docking, and try not find yourself in the outer rim with an empty fuel gauge.
Even in the darkest corners of space, you are not alone. Each character you encounter runs an AI that is constantly making choices based on their current needs and past experiences. They have physiological and emotional needs, ranging from basic wants like food, oxygen and water all the way up to deeper needs like intimacy and security. As captain, keep an eye out at the space port, scout out a crew and build those relationships. Your background will shape out how you are able to interact with other characters and if they will join your ship - have you developed a silver tongue or does fear rule your ship?
Based in the same universe as NEO Scavenger, Ostranauts will be rich with lore for those who wish to explore. After the collapse of civilization on Earth, colonies and factions formed - colonising other planets, moons and asteroids - with only those able to adapt to the harshness of space able to survive. As states and corporations spread their reach through the System, whispers of unexplained phenomena are creeping through back channels.
Blue Bottle Games encourages players to join the Discord, share modding ideas, and to help grow the world of Ostranauts. Modders who want to make their experience more unique are able to edit a wide variety of game data - most of the game's data is in plain-text files for easy access. If you have an inquiry, send us a message in either the Blue Bottle or Kitfox Discord.

Overcomplicated jumbled mess of a game.
I took a week off to renovate the house. Let's just say I didn't get much renovating done. The game is addictive and feels huge. I've played 50 hours and have only just started venturing out from the starting area. I like the RPG-style character creation and the large debt you have to pay off gives you a clear goal. Since ships are so expensive, it makes more sense to upgrade the one you start with. That also helps you learn the basics of shipbuilding while salvaging and tearing down other ships. I'd like an easier way to track quests that aren't on the current map, more dialogue options, and a better tutorial. Some in-game videos explaining the mechanics would be helpful. I did encounter one bug where the game would crash if I tried to load a save while already playing, but they fixed that and I haven't had any other bugs since.

I love the game but ill list a few of my issues with the whole gameplay loop aspect. The selective realism is extremely frustrating/unfair. They give you complex reactors and newtonian physics but decide shoes and oxygen tanks and high capacity batteries and tools should break down triple the speed they do in real life for no reason other than to irritate you or add some sort of "maintenance sim" aspect to the game. other than that its a great game despite the bugs i sometimes encounter.
Concept is great, some aspect of the game are tedius and boring ( interacting with any NPC for example ). Encountered a few bug, the latest one is no longer being able to install floors. That's not ideal as you can image. Might eventually be good, but right now it needs some more love
Can't recommend.
Fun and unique mechanics. It could use more in-game explanation of the mechanics. Right now, you will be searching for answers on forums or watching tutorial videos. A good example of this is conversations mechanics. Unlocking the blackmarket can take minutes if you know what you are doing, but no you have to learn by trial and error.
Surprisingly hardcore, suprisingly in-depth. If you like finicky physics and dumping all your in-ship atmosphere when moving some furniture, this is for you. Full freedom in building spaceships from parts you gather from drifting derelicts. A lot of fun. I haven't touched the social/relationships side of the game yet though.

zomboid without zombies and in space. the navigations of ships has no comparison to any other game. great.
i get why this game has mixed reviews. there is some truly honest to god awful ♥♥♥♥ in it. the developer quips need to just be removed (this isn't a marvel movie, i'm trying to take your serious setting seriously lol), the UI/UX/item management needs drastic improvement, docking and undocking takes way more clicks that it should, insane lack of verisimilitude for a 1.0 release (two bags the entirety of the game. you expect me to believe this literally solar system spanning society is reliant on TWO types of bags and theyre not even actual backpacks?) the tutorial ends abruptly after touching on just the basics. that last point is the most devastating, just like Kitfoxs other game Neo-Scavenger, most players are going to (reasonably) get caught up in the minutiae without ever getting to the "game proper" which is everything outside of the first area. the learning curve is steep and barely visible without context, but its there. each major location across the solar system is designed to teach the player something. k-leg, the first major area the player spends time in includes the aforementioned tutorial, but it doesn't explain ANYTHING about shipbuilding which is arguably what the entire area is supposed to be teaching you since you literally won't be able to get anywhere (not even to the outer reaches of the k-leg boneyard) without at least modifying your starter ship. that is the most egregious thing about this game. because if you can get past k-leg, then you really get to the bulk of the game. inner system travel teaches you how to use a torch drive both manually and with plots. venus introduces an entirely new atmospheric ship building system and ship racing. ceres makes you forget everything you've learned and build entirely for ship combat or mining. all of these areas are fun and even the story is kind of engaging... but it's all hidden behind a starting area that doesn't teach you the mechanic it requires you to master in order to "beat" it. that being said, if you put in the time and learn all these systems, it's great. nothing like coursing through the void beating your meat. no seriously, beat your meat while in deep space and see what happens.
