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?

“Early Access gives us a great opportunity to work together with community!
Actually we are already working with community very actively, and it brings a great results! Continue to reading this block for more details. Also you may check our development blog to ensure that development is very active!

Besides that, we are three friends and this is our first project. We are working on it without any starting budget and Early Access gives us an opportunity to work on our project without distractions.”

Approximately how long will this game be in Early Access?

“It is hard to predict release date for the game with such unusual concept and complex features. Especially if it is our first project.

Earlier we announced a release date, but development took more time than we expected, so we decided to not announce any further release date if we are not sure about it.

Actually release date is irrelevant and does not mean that game will become "completed" instantly. We release update almost every week and the game become better and better with each update. Besides that, we are constantly adding new features in our to-do list. So the game may be interesting and playable even while it stated as "Early Access".”

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

“Since we released the game we made a lot of work. We added multiplayer, save/load, trade.
An interface, ship constructor and production system was redesigned several times.
Graphics was completely changed from 2D to 3D!

In full version, we are going to improve all existed features, but in addition we plan to add:
  • Interaction with planets (gathering resources)
  • Several different types of star/planetary systems (with moons or gas giants)
  • More complex production system (not sure how exactly, we are going to discuss it with community)
  • More complex crew system (also not sure, will discuss it with community).
  • Heat system (necessity to use radiators to prevent overheat)
  • More various modules, functional devices and weapons
  • More types of procedural missions
  • Solve all bugs, optimize performance and improve usability
  • Overall improvements of game design, so the player will be able to slowly improve its technologies, fleet, encounter with stronger enemies and accomplish more complex procedural missions.
You may found more details in our to-do list

What is the current state of the Early Access version?

“Currently the game in Alpha stage. To answer this question will be better just to show a list of things which you can do in the game right now:

  • Fly around a star system with realistic physics and orbital mechanics
  • Construct complex ships and space stations using many various functional modules
  • Extract resources from an asteroids in order to produce fuel and construct ships
  • Trade goods between space stations
  • Accomplish procedural missions of several types (delivery, combat)
  • Buy or sell modules on a shipyards
  • Use several types of cannons, lasers, rockets, and energy shield to fight with enemy
  • Play with friends in multiplayer
  • Clean an orbit from a space debris and salvage resources
  • Use alternative control with mouse clicks to control your fleet like in strategy game
  • Enjoy the beautiful celestial movements and tell us what exactly do you want to see in the next updates

What is not ready yet:
Since it is Alpha, the game have some bugs, however we fixing all bug reports as soon as possible.”

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

“The price will be slowly increased during development according to quality and amount of features and content.
Initial price of first Early Access release was 8$.

At current state, the game cost 11$. When we increased the price, we asked a community about this and it was approved. You can read more details in our blog here and here.

When all planned features will be implemented and all bugs will be fixed, after stable release, we plan to increase price up to 20 or 25$.
Therefore, during entire early access you can buy the game with discount!

Some developers set the price for early access higher than after release, making money on the thirsty players.
We are not going to do that!

Actually, people who participate in early access make a great assistance for developers. They are making bug reports and send their ideas that helps to make the game much better. And most importantly, their feedback is really important because they give us enthusiasm, which allows us to continue to develop the project!”

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

“For almost two years of development we are working with community very closely! A huge amount of work has been done largely thanks to our community!

We're consider any ideas from community and your ideas really can be implemented in the game. You shouldn't thinking "I have so cool idea which will make the game so great! But probably developers are to busy to listen me". We read everything what you wrote to us and we glad to any ideas which will help us to make the game better together!

We receiving a lot of suggestions and bug reports. We have a huge list of suggestions in our to-do list and all bug reports added in to-do list and solved as soon as possible.

Tutorials and Guides
Our community helps us to create detail guides about the game.
Since interactive tutorial not yet implemented, we even added a link on this detailed guide from one of our community members right into the game!

Translations of various languages and correction of our English is done completely by our community!
We using GitHub to receive a help from anyone who wish to participate in localization.

Close communication with us
We are actively answer almost on anything what you wrote to us in Steam Community Hub.
Also you may freely add us in Steam contact list or use our Discord chat to ask us about absolutely everything! Most likely we will answer you within a hour or a day.”

Big update 0.8 Alpha - New game mode with aerodynamic space


We are happy to introduce, probably the most significant update during entire development of Celestial Command.

Despite the fact that this update have a version 0.8, this is only a first update in sequence. New game mode is made on more than 50%, but still quite raw. For now we decided to release it as soon as possible in order to show you an idea, but during next few updates we will add more and more significant improvements in this mode.

First of all, we want to explain why we decided to implement this new game mode despite the fact than during entire development we advertised a game, as a space game without "unrealistic liquid space".

Orbital mechanics in the current state causes a lot of technical restriction in the game. The concept when absolutely everything in constant movement it is very unusual concept for game development. Both in technical and gameplay terms.

Such gameplay have very complex learning curve, however, many users definitely like other features of Celestial Command, such as ship construction, trading, combat, but don't like how movement works.
In orbital space, such terms as "distances" or "locations" is very unobvious and hard to understand.

So we decided to implement a mode which will bring more classic gameplay using existed functionality of the game.
So in this game mode, terms of distances, enemy bases and locations is much more familiar for users.
Besides that, performance is much better, there is thousand of asteroids and almost hundred of space stations can work with good FPS.

Plus, this game mode allows us to implement some new features which impossible in orbital mode, for example, path finding, it means that now it will be possible to encounter a NPC traders or pirates which will really travel across the world and they will avoid all obstacles (this feature not implemented yet, but will be added in the next few updates)

However, we do not have intentions to make the game "casual". Physics still much more complex than in most classic space games.
In this game mode, mass of the ship (and cargo) have very significant impact on acceleration and maximum velocity, and also on fuel consumption.
In such game mode it is very interesting to find a proper balance between amount of cargo, size of the ship, amount of fuel, consumption of fuel, desired velocity etc.
In the next update we will improve a physics so size of the ship and its shape will affect its maximum velocity.

Important to note, we do not abandon development of orbital mode. Furthermore, many improvements of one game mode, instantly available in another mode. This is possible due flexible architecture which is based on the single core.
Aerodynamic mode may even help to test new features and gameplay approaches in stable environment, before it will be added into orbital mode. Which is much more complex to develop new features.

Also we want to remind that you can discuss an update and communicate with us about everything in our Discord chat.


  • Added brand new game mode with aerodynamic physics
  • New game mode: Added exhaust effect for small engines which is good for visualization of velocity and "sense of speed"
  • New game mode: Added speedometer on the interface which shows velocity of active ship
  • New game mode: Interface buttons which have sense only in orbital mode (such as orbital grid and stabilize orbit) disabled in aerodynamic mode
  • New game mode: Added moons around a planets
  • New game mode: Added new asteroids belt with many huge static asteroids and small dynamic asteroids which can be moved or destroyed.
  • Square grid now have small grids up to 100 meters which is also important for visualization of velocity
  • Small asteroids now have bigger size and now they have 8 sectors with resources. Asteroids will be destroyed when all 8 sectors will be depleted. This feature adds more sense to special ships which have several mining lasers around asteroid
  • Asteroids now have different HP based on its size
  • Significant optimization of core which improves a performance in several times. Loading of games and ships now much faster.
  • Localization files updated, thanks for this for community

Update 0.796 Alpha - Improved save load


We noticed that current state of save / load functionality works not exactly how we want. It is important feature so we decided to improve it.

So now if you will encounter a bug or just a complex situation, it should not be a problem to load previously saved game and progress will not be lost due flaw in save / load function.

Check the changelog for more details.

Also we want to remind that you can discuss an update and communicate with us about everything in our Discord chat.


  • Now you can save the game with specified name (not just overwrite the current one)
  • When you click on existed saved file in "save" menu, its name will be automatically inserted in the input field of name
  • Added warning window which will inform you if you trying to overwrite existed save file and offer an option (Back / Overwrite)
  • Now auto save generates up to 9 saved files (instead of just 1 file which is constantly rewritten)
  • Added button "Load" in game menu, so now you can load a game right during existed game
  • Added "loading screen" which appears during loading
  • Added button "Open folder with saved files" which located in save / load window (works only on Windows platform)
  • Entire save / load window is redesigned
  • Now when you going to load a game, multiplayer checkbox is disabled by default
  • Button "Contribute to localization" now opens URL in your internet browser instead of Steam overlay

  • Fixed an important bug which caused an error when you tried to save the game
  • Fixed an error with incorrect captured image of saved ship in "saved ships" menu
  • Fixed an error in station's docking AI

Steam Greenlight

We thanking all who voted for us, individually thanks people who give ideas and evaluated our innovations, thanks to them we were able to choose the correct path.

About This Game

Celestial Command is a realistic sandbox space game which unites a real orbital mechanics, ship constructor and some features of typical space games.

Gather resources, construct space ships and stations, produce fuel, generate energy, trade between stations, complete contracts or fight with pirates in a 2D world where everything in constant orbital motion, without "air friction" and without maximum speed limits.

Realistic Orbital Mechanic

The world of the game works based on simplified orbital mechanics. Everything in state of constant orbital motion. Perform orbital maneuvers and keep your space ships on stable orbits to prevent crashing on a planet or loosing ship in deep space.
The physics simulates in 2D space, this makes flying and navigation enjoyable and easy but also generates a lot of interesting situations due physical collisions which are more often in 2D space than in 3D.

Fully Customizable Ships and Space stations

You can build your own ship part by part. Each part of the ship is individual, it has own functions and parameters. Therefore, abilities of your ship are completely dependent on the modules from which it is assembled. You can build small explorers, large industrial ships, carriers, defense satellites or whatever you want.
Each module can be detached or attached to the ship right on the fly, which allows to transform your ship using found modules.

Ship Management

All resources of the ship are limited. Including fuel, energy, ammo and construction materials, so store them and use them wisely.

Command a Fleet

You are not bound to a single ship. You can build as many ships and space stations as you want. And you can switch control between them anytime. Also it is possible to control your ships not only directly, but also giving movement orders.

Seamless Star System

Explore a procedural world filled with planets, asteroids, space stations and other things. The world of the game is completely seamless, you can zoom out from your ship to the entire star system.

Gather Resources

Mine asteroids for useful resources or salvage wreckage of broken ships in order to build new modules and produce fuel.

Economy, Trading and Missions

Trade goods between stations or complete procedural missions provided by NPC stations and earn additional credits to buy new modules on a shipyard.

Fight the Enemy

Build various types of devices to fight against enemies. Cannons, lasers, rockets, shields and more.

The game has now been in active development, so even more interesting features added almost each update!
Check our development blog for more information about development and future plans.
