Ostranauts "Wear & Tear" Update Is Live!

Hey Folks!

Ostranauts v0.9.0.0 is now available on Steam. Named "Wear and Tear," this patch represents a major feature update, and includes a batch of new content plus fresh gameplay loops to explore.


As the name suggests, the "Wear and Tear" patch adds new functionality to the game wherein items, equipment, and ship parts degrade and take damage in new ways.

Gone are the days of pristine derelicts in the Boneyard. What you'll find now is that every ship is in a unique state of disrepair, with major parts that suffer nuanced fail conditions like gas leaks, thruster sputter, power shorts, light flickers, efficiency drops, and even internal component failure.

With these new problems to solve, you and your crew will need the right tools to get vessels in working order. So we've included a range of new toys to play with, from friction welders to angle grinders, all powered by a new chargeable battery system that works with EVA suits as well.

For best results, you are encouraged to start a new character.

Old saves will not work in v0.9.x and later. However, we have created a new opt-in branch on Steam called "legacy_08" if you wish to continue your current v0.8.x character. See Steam's Tech Support forums for more info on opting-into other branches.

As you can tell from the changelist above, the new patch is focused on creating a more complex, dynamic, and customizable journey from busted ship to zooming whip. As a first level of complexity we've designed a custom shader that procedurally applies damage and visual noise to every item in the game. This damage increases over time and can break the part when it reaches capacity, so you'll have to use the restore action to keep parts in working condition.

On top of that, crucial ship parts like Nav Stations and RCS systems are now made up of internal components such as motors, motherboards and heat sinks. This means repairing them isn't as easy as a simple restore action, as you'll need the right components to make them work.


In addition, broken ship parts are no longer a binary of "working" or "not working." Instead, parts fail in dynamic and variable ways, from efficiency loss to gas leaks to intermittent thruster sputtering. These failures combine to create crises unique to your game story, and force you to creatively problem solve or else face doom in the void.

We wouldn't want you to go it alone, so as another feature we've spruced up our crew and AI system. Crew members now automatically restore your ship as a default behaviour, assuming you've given them the right tools. We've added a new Behavior: Auto/Manual mode toggle, just in case you want to tab from crew member to crew member and micro every action yourself.

As always, please tell us what you think! We thrive on your feedback and love to hear from our players in Discord and beyond.

Thanks for reading and…oh crap. What was that noise? If that's my Hydra failing again, I swear...
