Navigate your scrappy ship through the boneyard in search of valuable parts in abandoned vessels. Use salvage to upgrade your ship, or sell it for cash to pay down your mounting debt, or restock fuel, air, or food. Fly and role-play aboard your dream spaceship in this hardcore noir space-sim.

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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.

Takes a few minutes to figure out commands/controls but once I did I've been having a lot of fun. It's not fast-paced but I'm loving it so far.
Fantastic hard sci-fi sandbox game. Remember: Filling your ship with only Oxygen makes it quite flammable! Mix the Oxygen with Nitrogen!
My character was back at K-LEG station, angle grinding some junk inside his ♥♥♥♥♥♥ little cargo tub, smoking a joint (as you do), when one of the patches on the floor finally gave out. Took a second for the O2 alarm to start going off, but in that time the micrometeor-sized hole it covered managed to drive up all the AC units and pumps and, after a few more moments, drain the battery power. Lights out; interior airlock door shut. Of course, K-LEG's official emergency response policy is, "you're on your own," so power and O2 hookups stayed shut until paid forward. Had a crowbar nearby and managed to pry the doors, as hypoxia set in. At least they did me the kindness of opening the interior station airlock. 10/10 emergent gameplay.

Iindie space survival seeks new vict....erm i mean players... hardship guaranteed.... survival not so much. Space sucks, literally... the oxygen out you lungs, the blood out your skin, and if the environment is not, then the NPC pirates and 'others' will try, the 'corporation' wont physically bleed you dry, but will get their cut of your profits.... 10/10 love the work and really enjoying the direction this game is going. yes there's bugs and a few glitches, but the developer is quick to address them, and the project is constantly moving forwards.
A loot goblin's paradise, with a healthy dose of life sim in the lovely horrors of the void. This is shaping up to be the best game in its sub-genre for me.
Just yes.
Отлично!
×硬核太空建造 √华强北模拟器 “您并非天选之子,您并不强大。”你和NPC一样,没有任何生理优势,包括如何拖动一只重达40kg的箱子。当O₂耗尽,他们会被憋死,你也一样。并且,该死的,哪里都有房地产商和黑中介,连空间站都不例外。 生活在太空,你真正需要发愁的是每日快餐卡路里,具体来说是吃热狗还是煎饼果子,加不加番茄酱。你那个破烂飞船没有空调?去装一个。飞船里没有客厅和沙发?去装一个。睡觉不踏实,需要窗帘?去装一个。 Ostranauts的太空没有奥德赛式的史诗折跃旅行(其实是有的,只不过你得亲自打造能实现这一切的设备),但却充满了足以让广大垃圾佬们无比激动的废品堆。制作组甚至贴心地设计了不同品牌的电动工具,他们当然不像现实中的**瑞士军刀**那样好用,因此你有必要了解一下不同品牌的工具电池是否能混搭、如何充电等一系列鸡毛蒜皮但却十分致命的问题。在搞懂这一切以后,你完全可以期待一下二手交易DLC(闲鱼:??)。 感谢空间站的保安,是你们的存在才不至于让一切都零元购。打工人,打工魂,谁特么不想润去火星住大公寓啊?是我不想去吗,是我去不起谢谢。总之,欢迎来到华强北,定个小目标,赚它一个亿好不好?
