About Ostranauts

✦ AI summary

Manage your ramshackle crew and ship while scraping by in a harsh solar system, making critical choices that ripple through your story and gameplay. Every decision—from your character background to how you customize your vessel's physics-defying systems—shapes your path from indebted scrapper to independent captain or complete failure.



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.

What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

Ostranauts is a deep, granular space survival sim that blends ship scrapping, flight physics, trading, and numerous other systems into an impressively ambitious experience that rewards patience and experimentation. However, players consistently report that the 1.0 release feels rushed with persistent bugs, unclear goals, frustrating controls, and tedious ship-building mechanics that can undermine the experience even during otherwise engaging moments.

It is year something something. Humanity has invented interplanetary space flight, but did not bother to invent flight computers. We fly by stick, we fly by gut feeling, welcome to Ostranauts... The idea works great in empty space and fails miserably once you try flying near gravity bodies. This game promises you scale and intricacy and then delivers nothing once you try going past the initial scavenging zone. The remote stations are mostly meaningless, the interplanetary flight boringly slow, and at the end of it you might not even be able to dock, because you have to literally guess motion parameters when flying near gravity wells.

I just can't give this game a good review. My saves keep getting corrupted to the point of where I just lose hours of gameplay or can't even load parts of OKLG the starting area. I'm just over it.

Single-player SS13 made for/by insane people. First off, a lot of the criticisms floating around this game are 100% valid, quality of life is very much an afterthought especially once you get into automation, and a lot of systems could use a second pass or a better tutorial. Still, it's in a very playable state, and i've come to love the jank of passion projects like these. It's really games like these (think kenshi or songs of syx) that activates my almonds, and i think you should give it a shot if you have even a little propensity for janky ambitious passion projects.

This is exactly what I want in a game, except.. it isn't. First the character creation.. it's literally like the same type of options every time. How is there no variety and basic imagination for some basic back stories? The way this game works with needing make money at some interval because you are being charged constantly is just.. not fun. And the docking system is fun for the first couple of times and then not at all. So this is like something that should be really good but just isn't.
