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!

Huge Update 0.86 Alpha - New production system, inventory, trading, working multiplayer and more!

This huge update is ready for release! The update consist of 3 major and important aspects:

New production and inventory system
Added a lot of new items, new method of construction, new production modules, new system for distribution of resources. Storage containers now may contain more than 1 type fo resources, and more.

Redesigned and improved trading
Added many types of space stations. Stations now can be found in different locations in the galaxy. Fixed important bugs and exploits.

Now everyone should be able to host a server, and the server will be properly visible in the server list!
This was unexpected! Earlier only small percentage of users was able to host a server, which was definitely not good, but we thought that in order to solve this problem, we need to rewrite half of the game from scratch, which requires a lot of work, so this task had low priority.
But turned out there is a solution which allowed us to quickly solve this technical issue just in a few days! We are super excited with the fact that multiplayer now is really acceptable for entire community!

Also, we fixed a lot of bugs related for multiplayer! Trading and missions now should properly work in multiplayer! Also we found out a new way how to synchronize positions of objects between connected users, so now ships movements should be much more smooth and stable! No more "chaotic jumping around" for connected users, especially while you are trying to dock to the space station in orbital mode.


Also, in order to not duplicate the same screenshot with the new features, you may check a previous blog posts which was published during development of this update.


Overall, this is just a quick overview of this update. Please look at the full change log for more information.

Also, note that this update is not very polished. It was too long in development, so we decided that we already should release it. Overall everything should work, but may contain some significant bugs and flaws, but we are going to fix all crucial issues ASAP in nearest updates.

Information for people who tested a test build of this update: Invite via Steam overlay and Discord rich presence features requires some additional work and not included in this release. Will be added a bit later.

News of development - Better asteroids belt and warp drive UI

Seems like soon a new update will be ready for release. We are already working on fixes of critical bugs and flaws.

So far, you may look at the new asteroids belt which now looks more like it should.

Previous variant:


Also UI of warp drive now should be much more intuitive. In order to jump, your ship should be located in yellow area.

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.


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.

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.
