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 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.”

Update 0.864 Alpha - New engineering modules, shipyards and construction

In this update we made very important improvements related to how construction looks!

Some time ago we replaced engineering drones with the robotic manipulators, because this is much more physically realistic and also it could looks better in terms of visual design. However, first version of robotic manipulators looks not very good and we are not too satisfied with its design.

Also we wanted to implement a "classic sci-fi space shipyard" which actually do something. In some sci-fi games and movies you may encounter a big scaffolds with a space ship inside, but usually it is just a decoration, so we want to implement a shipyard with scaffolds which really do something inside using its robotic manipulators with complex animations and visual effects.
We had some kind of shipyard scaffold before, but we removed it because visual design was not very good.

And since construction of space ships it is very important aspect of the game, we decided to significantly improve this aspect!
We presenting you new and improved engineering modules, and modular shipyards!

Added 2 modules for shipyard and 1 new engineering module of bigger size

When these modules combined together, it turns into some huge and impressive constructions!

New engineering modules looks much better than before. Now it much more compact in standby mode and also you can properly paint it in any color

Engineering modules now have much better animation, not so tall during building and also there is a yellow progress bar on top of it

Small engineering modules for small constructions drones also looks much better. By the way, engineering module can't repair itself, so small drones could be useful for that

More drones for deep space engineering operations! Very useful in case if nearest shipyard is too far away

As you can see, now drones it is not just a fake animation, it is a real ships, with fuel tanks, engines, storages and hit points. This is exactly what we wanted to achieve when replaced old "fake" drones with robotic arms.
This could be especially interesting for multiplayer when people will take different roles.
Or in the future addition of capital ships, these drones can be stored inside a capital ship hangar.
Also you can customize a drones like you want and design different models of drones for different tasks.

Overall, we are very satisfied with how engineering modules, construction process, drones and shipyard looks now and we are happy that issue with construction is solved!
A bit later, we will redesign an NPC stations so they will have a new shipyard and its new game mechanics.

Hope you like the update!
Also the game 20% off during Halloween sale!


  • Added Engineering Module Mk3 (2 times larger than Mk2)
  • Added two decoration modules which is suitable for construction of shpiyard
  • New model of engineering modules
  • Added animation for engineering modules
  • Added progress indicator on engineering module
  • UI: Radius circle of engineering modules a bit redesigned
  • UI: Inventory of container no longer will be displayed when you are trying to deconstruct it with the engineering module
  • UI: Now the game will warn you if you are trying to create a world or save a file with invalid symbols \ / : * ? < > | "

  • Now you can change color of engineering bay and grabber (the same as any other module)
  • Now when you are going to build a module and your ship have more than 1 engineering module, placement will be allowed within a range of all engineering module (not only one of them)
  • Fixed an error when you are trying to save a game or a ship with invalid symbols
  • Now when you are going to save a game in file and your are pressing on existed save file - double click on this file will not load a game

Update 0.863 Alpha - Redesigned and improved warp gates


We decided to redesign how a warp gates works. Now it "teleports" an objects from point A to B instantly, however, activation of a gate now requires some time.

Also we added various visual and audio effects for warp gate and more information on UI about its current state.

What about warp drive - its functionality still the same, the ship really travels inside a warp sphere.

Why it is done? There is a several reasons:

1. In terms of realism, is looks strange that ship which located in a tunnel of warp gates should be located inside a small circle and should not touch a circle. It creates a questions, such as, what is center of circle? In case of warp drive, it is obvious, center of circle - it is a center of warp drive. But in case of warp gate it looks weird.

2. Another example of question about realism, what if two ships departed from two different gates in direction of each other? They will works well, but you may ask, if this is the same warp tunnel, why they are not collided with each other? This is also seems weird.

3. Warp drive will be more epic in relation to warp gates, so when you will achieve your first warp drive and will go to expedition, it will provide you more unique and interesting experience.


  • Changed a way how warp gates works. Now it have instant teleportation, but not instant activation
  • Now warp gate activation will cost you a credits
  • Added a normal UI button to activate selected warp gate and also additional information about selected gate
  • The second (arrival) warp gate now also have a delay timer after jump
  • Added lights to warp gate which represents its current status (Ready \ Activation \ Recharging)
  • Warp gate no longer applies ejection force after arrival. Instead of this, relative velocity of your ship will be the same
  • If someone going to jump out of warp gate, you will see a special effect on its gate, also it will be temporary unavailable for jump and also the gate will push out all objects inside which may block an arrival
  • UI: Now you can close inventory transfer window using Esc button
  • UI: Now you load a game using double click

  • Now warp gate leads to the correct warp gate in another system (no longer always at the same warp gate)
  • Added a warning message in case of game error during warp flight or warp gate jump - it should help to fix an issue when sometimes it is not working as intended
  • Now data about save file will be displayed correctly when loading window is opened (no longer needed to clicks on each file in order to display its data after 1 second application freeze)
  • Fixed an error with incorrect spawning of static asteroids in asteroids location
  • Fixed an incorrect rotation of "Center of Thrust" icon for some ships
  • Ships no longer have incorrect initial velocity after exit warp drive flight in aerodynamic mode
  • Warp gates now properly works in multiplayer

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.


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.
