Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

Stable Orbit is in Early Access to get feedback on the game in its current form, and help me decide what features and content I still need to add (or remove) before I can call the game complete.”

Approximately how long will this game be in Early Access?

Stable Orbit will be in Early Access for approximately 6 months total. My plan is to release the completed game in the spring of 2017.”

How is the full version planned to differ from the Early Access version?

“The full version will differ from the Early Access version in several ways: the number of modules you can build and research will be limited during Early Access, to help me work out the kinks of balancing the various simulation parameters and systems. Once the full game launches you will (over the course of the game) have access to all modules the game offers. Additionally, there are several features that are currently in a testing stage and will be either further developed or removed based on the feedback I get from you, the player, during Early Access. Finally, much of the art in the game is non-final - you can expect the final game to look even prettier than it does now.”

What is the current state of the Early Access version?

“The game is already fully playable, but some features are not yet complete and (as mentioned above) the number of modules you can build during the Early Access phase is somewhat limited.”

Will the game be priced differently during and after Early Access?

“Yes, the price will increase when the game leaves early access.”

How are you planning on involving the Community in your development process?

“I intend to involve the community in several ways:
  • I will ask players to vote on feature priorities and design alternatives
  • Players may opt into a "weekly build" branch, which will have the latest code and features -- though may be less stable than the default version
  • I will listen to the feedback given to me through the Steam forums

Prepare for Blackout

Another Stable Orbit update glimmers on the horizon, Blackout. This update is named after one of the myriad of problems your station may encounter once the update goes live: a communications blackout due space weather. While Blackout is still a few weeks from release, I'd like to take this moment to tell you about what is coming up.

Events, Calamities & Disasters
The first major new gameplay system that Blackout introduces are events, calamities and disasters. Events are benign or even celebratory occurrences like, say,  a party thrown for the 100th astronaut to board your station. Calamities add small problems to your mix of worries and include incidents like power failures, shuttles not launches due to bad weather conditions and the aforementioned communications blackout. Finally, there are disasters, which are rare events with a massive impact on the continued operation of the station. Ironically, since this is space we're talking about, even big disasters have their causes in the smallest of things. Your shuttle pods may become grounded for months at the time after a fueling incident (thanks reality) caused an explosion on the launch pad. Alternatively, you may loose an entire section of your station due to a CBM failure.

Orbit Controls
Additionally, Blackout introduces orbit controls. Up to now, your station in Stable Orbit "magically" maintained a perfect orbit around the earth - but that's not how space stations really work. With Blackout, your station will be in constant and steady decline and, like the real ISS, will require regular thruster boosts to maintain its orbit. By default, the station boosters will fire automatically at the appropriate times and all you'll have to worry about is the placement thrusters around your station (incorrect thruster placement will impair your stations ability to control and stabilize its orbit). You can also disable the automatic boosting if you wish to attempt to maintain a stable orbit all by yourself.

Orbit Map
While the orbit map doesn't really affect gameplay, I believe it is nonetheless going to be a fun addition to the game. Most obviously, the map will show you where on (or should I say 'above'?) earth your station is and where it is headed. The fun part is you can click on a spot on the map to cause the station to use the maneuvering thrusters to alter its course until it flies over the spot you just clicked on. Orbital tourists, rejoice!

Be kind, rewind
The final new addition that Blackout brings is not actually new at all and has technically been in the game since the very beginning: the ability to rewind time. I've actually demonstrated how the feature works at Gamescom last year, but I was not very happy with how you, the player, got to control the feature and therefore felt that part of the user interface needed a major rethink. Now, with Blackout, I believe that I've finally got this part right and ready for you to play around with.My hope is (and always has been) that having the time rewind feature will allow even the most casual players to enjoy the "full" experience, disasters and all, since they can always go back and try a different strategy even if some major event causes a complete breakdown of their station. Of course, for the hardcore fans who want nothing of this sort, there will be the option to turn the time rewind mechanism off entirely.

Coming Soon!
I hope you are all excited for the changes coming with Blackout. I am working in full overdrive mode to get everything finished and polished as soon as possible. You can look forward to having Blackout in your hands in a couple of weeks!

Perihelion Update - Available Now

Perihelion Update - Out Now

Hello world!

The latest update for Stable Orbit is live! It's called Perihelion, and includes a whole bunch of new gameplay features - Like Research Contracts, New Modules, Station Upgrades and Waste Management.

As well as the usual optimisations and fixes one would expect from an update, one particular piece of weirdness has been fixed - Module Intersection Detection. What's that, you ask? Well, read on!

Update Notes

Research Contracts
The biggest change is the addition of research contracts. Up to now, making money in Stable Orbit was easy! All you had to do was build a lab, make sure it has power and there is enough crew to man the lab (preferably on rotating shifts) and presto: oodles of money soon come flowing your way.

Those days, my friends, are over! Now, you will earn rewards by completing research contracts offered to you. Some contracts will offer a quick buck - such performing Bone Density Research to measure the effect of space travel on humans.

While others may offer big wins, such as all new unlocks for your station – but you'll need to accept it before the contract expires! Some contracts will require that you install specific upgrades in your laboratories, or reach a higher science level, before you can accept them.

Module Unlocks and Upgrades
Now you have the ability to unlock new, larger modules, as well as upgrades that can be installed on (some) modules.

Upgrades come in two forms: “standard” upgrades, which can be installed at will and “special” upgrades, of which only one can be installed per module. Standard upgrades include things like capacity boosters for your storage modules. Special upgrades allow you to do things like specialize your laboratories for research in one particular area – say physical science.

This sets the basis on how your station will be upgraded, and more will be included in future updates.

Waste Management
Looking after your station is a delicate balance of resources for you to manage and balance against the other needs of the station. In this update, another resource has been introduced - Waste.

If you let too much waste pile up, living conditions in the station will deteriorate and give your crew a reason to abandon you. On the other hand, waste is a resource not to be wasted, as the new Waste Recycling module will allow you to extract water, partially closing the loop on that resource.

Module Intersection Detection
Up to now, you could place modules on any free CBM, even if placing a module there would cause it to intersect with other parts of the station.

Fixing that has been on the to-do list pretty much since the very beginning, but so far it has always lost out to doing things that have had a bigger impact on the overall game play. Also, most of you were avoiding intersections while building your space station, even without the detection in place. You are good people! From Perihelion onward, the game will make sure that everybody behaves (when it comes to placement of space station modules, that is!).

What's Next

There – Now you know what is brand new to Stable Orbit. Hope you are all as excited about these new features as we are! As is by now tradition for these blogs about new features (assuming you can call something you’ve done twice already a tradition), we'll close out by looking ahead what else is in store for Stable Orbit.

The update after Perihelion will be called Blackout. This will be include the Orbital Management and Disasters & Events features from the roadmap. ETA - June(-ish).

Following that will be Umbilical, adding the Advanced Truss Structures and Pressurized Mechanics features and then – finally – the big one: Zenith, which will round up all the features promised in the roadmap to become the official “1.0” release of Stable Orbit! Yaaay!

Let us know what you think of the latest update over in the Discussions board. See you there!
