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?

“It is amazing to work with community! We are reading every suggestion and answering on your every question. Please feel free to join our Discord chat and ask or suggest whatever you want. The game in VERY active development, so follow our development blog for news.

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 http://steamcommunity.com/sharedfiles/filedetails/?id=557510735 from one of our community members right into the game!

Huge update 0.882 Alpha - New tool for orbital navigation, new looting, salvaging, mining, crafting and base building gameplay!


Ship building and production it is the most important aspect of the game, however we realized that production is so complex, unbalanced and inconvenient to use so basically no one use it in the game.

So we decided to focus on this aspect and greatly improve it!
We added a lot of various significant improvements which should make the game much more enjoyable.

Overall, the main idea that game design based on "Complete missions, earn credits and buy new stuff on the market" is much less interesting than game design based on "Gather resources, refine it, construct own production base and produce more powerful stuff by yourself".

So from this update we are going to move the game toward the second variant of game design.
Of course, NPC, trading and missions will not be removed from the game, but importance of these aspects will be reduced in comparison to crafting and base building aspects, especially during initial phase of the game.

Simply put, initial phase of the game should be more like "co-op crafting survival game" and more late games may have some elements of "economical simulator game", but not vise versa (like in previous version of the game)

And we think it is a great plan which should make the game much more enjoyable than before.
And this have a sense, because gameplay like "do missions and buy stuff for credits" is very standard gameplay for many space games, but co-op realistic crafting and survival gameplay in space is much more rare, so this is exactly an aspect which should have a maximum attention in the gameplay.

New tool for orbital navigation

Highly requested tool for better orbital navigation is here!
Navigation in space no longer random. Orbital navigation is much more enjoyable now!


New mining

Now it should be much more enjoyable. Unrealistic and inconvenient sectors of asteroids was removed, So it no longer necessary to fly around an asteroid to mine it completely. New user interface show you what exactly you mining, when it will be done and where gathered materials unloaded

New salvaging

Now engineering modules is capable to automatically salvage debris in range. Salvaging now is much more comfortable and enjoyable to use!

New inventory UI, icons and production capable starting ship

Solved a nasty issue with inventory windows which overlaps entire screen and requires to rearrange windows manually. Now inventories is much easier to manage.

And new starting ship is capable to performs construction operations right from the start of the game. Also now it have proper engines, because flying around using maneuvering engines was weird.

This is initial update which started to move the game toward the new game design. In the nearest updates we will add even more improvements related to this aspect. We have a great plan about how to make the game is much more playable and enjoyable very soon!

Also, check a full change log for more information.

And also, the game is 20% off during Lunar New Year Sale!



Large Improvements
  • Added a special tool which helps to direct your ship on correct trajectory in order to approach to a certain object in orbital mechanics mode!
  • Implemented a new method of salvaging. Now salvaging of debris performed not with "cargo gate module", but with "engineering module". Robotic arm now able to extract parts from debris, manually on your command or automatically within its radius. This process also requires an energy. Cargo gate no longer functional and just a decoration element.
  • Significant improvements in mining system. Due various new effects, usability improvements and rebalanced, now a process of mining should be much more interesting and enjoyable than before!
  • Added salvaging module which allows to recycle broken parts and extract usable materials
  • Added small refinery, production and fuel generator modules
  • Starting ship redesigned, now it have engineering, production and refinery module which allows you to salvage debris, repair and construct new modules right from the start
  • Solar panels now rotating to a star automatically (necessity to rotate it manually didn't added any interesting aspects to gameplay and was just tedious)
  • Now when you hover cursor over a module in build menu you may see amount of modules which can be built using available parts on the ship or a list of missing parts
  • Various changes in recipes and resource distribution in asteroids now allows you to build your space station much earlier than before (earlier it was so complex so almost impossible)
  • Added missing icons for ores and refined ores
  • Redesigned inventory windows. Solved an issue with inconvenient rendering of large inventory windows for ships with multiple containers

Small Improvements
  • Added "Show trajectory for active ship" button which makes visualization of trajectory much more convenient. Trajectory now correctly displayed when you switch control between ships or if active ship received damage and lost some modules
  • In module control panel, texts "true" and "false" replaced with localized "Yes" and "No"
  • Added special icon to distinguish normal construction items (such as steel plates) from its damaged version
  • Date in blog time line window in main menu displayed in 09.01.2018 format instead of 9.1.2018
  • Reduced size of visual effect of large chemical engine, so now it looks more suitable to the size of the engine
  • Ammo production moved to basic production module
  • Reduced max thrust of reactive engines (1400->1000 and 3500->2000)
  • Added description to ore refinery, production module, research module, scanning module and orbital scanner
  • Optimized rendering of trajectories
  • Added audio effect for production modules
  • Scanning module will give a message if there Is no useful data in scanned object
  • Build menu of production modules a bit redesigned
  • Locked modules in build menu now completely invisible (instead of just locked with the lock icon)
  • Default amount of asteroids increased from 100 to 300

  • Space stations no longer physically transparent
  • Parameters of turrets now properly save loaded
  • Production modules no longer functional until fully built
  • Build list of production modules now properly save loaded
  • Fire debris mode of turrets now works again
  • Amount of energy in power storage now displayed correctly in case of low values
  • "Show orbital parameters" button no longer displayed in aerodynamic mode
  • Removed incorrect "Star server" description of "Display options" button
  • Preview of module now have more accurate position relative to cursor
  • Added localization support for scanning module and orbital scanner

Update 0.881 Alpha - Improved saved ships window and important bug fixes

Here is a redesigned and improved window of saved ships, which now looks much better, have better usability and much easier to use.

Previous version

New version

Compact mode

Another interesting feature, when you save a ship, preview image will be created from the same point of view and with transparent background, as result, such images looks very nice, especially if shared somewhere with dark background, such as here, on Steam, or in Discord chat.

Also, turned out that some ships, especially a large carriers with several docked ships, especially inside enclosed space, may cause an explosion after this ship will be loaded from save file. Of course, this is a serious issue, and it it fixed in this update.
So now a ships like this could be loaded without any issues! Important fixes for future capital ships.


  • Camera: Improved "Reset pan" button. Camera no longer zoomed close to the ship (it turned out not too comfortable), and rotation now have smooth effect
  • UI: Prices in trading window now displayed with convenient spaces
  • Tech Tree: Small redesign of tech tree
  • Tech Tree: All modules of the starting ship now available for construction right from the start and no longer requires research
  • Optimization: Ships save loading now a bit faster
  • Ship Save Loader: Redesigned window of saved ship. More convenient design and usability
  • Ship Save Loader: Saving a ship no longer freezes a game for 1-2 seconds
  • Ship Save Loader: Added option to reduce size of ship icons in the saved ships window
  • Ship Save Loader: Now images of saved ships adjusted automatically and always have the same camera angle and position, also images have transparent background. Various UI elements and planets no longer visible on ship images, as result it creates very nice looking data base of ships. Source images of ships also looks very nice on websites or Discord chat which have dark background
  • Ship Save Loader: Now it is not necessary to select a ship if you want to save it. If nothing is selected, the currently active ship will be saved
  • Ship Save Loader: Now you can quickly spawn multiple ships using Shift+Click
  • Ship Save Loader: Now you can save ships in non-sandbox mode (loading is not available yet, but will be added later)
  • Ship Save Loader: Now you can rotate camera while placing a ship. Place mode will not be disabled
  • Ship Save Loader: Added delete confirmation window, so now there is less chance that you will accidentally delete a ship file

  • Fixed serious bug with incorrect loading of docking ports which sometimes may cause an explosion on loading, especially for a large carriers with several docked ships
  • Fixed serious bug with incorrect loading of links between modules which caused to incorrect link between ships which was located close to each other while save file was created, which sometimes caused an explosion on large carrier ships
  • Asteroids now properly respawned
  • Center of Mass and Center of Thrust icons now properly rendered
  • State of nuclear reactor now properly save loaded
  • Solved a situation when the game was saved while NPC ship was inside another ship, and after loading it caused an explosion

About This Game

Celestial Command is a realistic co-op crafting survival sandbox space game which unites an orbital mechanics, realistic physics, ship constructor and various features of classic space games.

Mine asteroids, salvage space debris, build space ships and stations, manage fuel and energy, trade goods, performs missions and fight against enemies in large open world with realistic 2D physics based on orbital mechanics or in alternative, more classic game mode.

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.


Explore a procedural galaxy filled with various types of stars, black holes, planets, asteroids, space stations and other interesting things which we will constantly add in the future.

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.

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.
