Space Commander

Space commander

This game is an experiment. I always wanted to build something like browser space game strategy. Knowing English language is a must, because describtions and messages are a crucial part of this game. Please study this instruction first to learn the basic concepts.

UEF - Earth Federation continues to Explore unknown regions in the space. They’ve sent expedition to the outer Galaxy to establish colony there. After finding a suitable planet, the expedition build settlement. Suddenly, the capital ship was attack by alien armada. After heroic fight the ship was destroyed, but the aliens also withtdraw from the combat. The humans were left alone without any chance of escape back to Earth. It was only a matter of time when the aliens will attack again. The only hope is to raise the armada and destroy aliens home planet.


Space Commander is a strategy game, where you will manage your own colony, build buildings, discover new techs and build ships to defend your planet from alien attacks. At the start of the game you will only have small defense fleet and several resources. Your objective - to locate and destroy all alien colonies and finally destroy the alien capital planet - Cligg Prime. To achieve this goal, you must build ultimate weapon - Solar Destroyer and send it to the aliens capital planet. If Solar Destroyer survives attack and all alien colonies will be destroyed, you will win the game. But be careful - enemy will also try to build ultimate weapon by stealing resources from you. If the enemy first develop Solar Destroyer and beat your planet defence, you will lose the game.

War Room - your management console

After starting new game, you will be directed to the War Room. Here you will manage all aspects of your colony. By clicking certain buttons you will move between management screens. Note, that some buttons will be unavailable after start of the game. You will need to develop certain techs to unlock new choices. At the top of the screen you will see three main resources of the game - Metal,Crystal and Fuel. Resources are needed for develop techs, build buildings and ships. If you want to pause the game, click on the PAUSE button - you will be redirected to the Main Menu, but with option to continue game.

Star Map - plan your journeys

After clicking star map, you will see the map of the galaxy. At the beginning of the game you will see only a small piece of space around your home planet. If you upgrade Astronomy tech, the map will expand, revealing more places. White dots on the map represents Planets. If you want to interact with them, simply move cursor on the dot and press A. A dropdown menu will appear with the available options:

  • SCOUT - if you have Spy bots, you can send a scouting fleet to the planet. When the fleet reaches target, a new report will be available in the Reports section.
  • COLONIZE - if you have Colonizers, you can send a colonize mission. When the fleet reaches target, a new colony will be established.
  • ATTACK - the planet is an alien colony. If you want to attack it, you will be redirected to the fleet selection screen to pick the ships and send them to attack.
  • SET TRADE ROUTE - option only available if the planet is your colony. If you have enough transport ships, you can set a trade route to increase your resources mining.
  • ABANDON PLANET - option only available if the planet is your colony. It will remove colony from the planet (also removing trade route if was set).

Technologies - develop!

If you build Sciece Lab, you will unlock Technologies button. Here you can switch between current technologies and research them. You must meet resource requirements (resource
cost) and Tech requirments (red describtion beneath tech describtion). If both requirements are met, research marker will glow, informing that tech can be researched. Press A to upgrade it.

Buildings - build your colony!

After clicking buildings, you will be redirected to build screen. Here you can switch between structures. You must meet resource requirements (resource cost) and Tech requirments (red describtion beneath building describtion). If both requirements are met, build marker will glow, informing that building can be upgraded. Press A to upgrade it.

Reports - gather intel

Reports give you access to spy bots analysis. Each time spy bot will reach the target a new report fill be generated - you will be informed about it. There are two types of reports:

  • MINING - information about planet resources - needed to build necessary transport ships for trade routes.
  • HOSTILE - information about alien colony garrison and fleets - needed to plan an assault. You must upgrade intelligence to gather more intel about enemy ships.

Active Fleets - track your fleets movement

Here you will your fleet missions status - the fleet will reach its destination, when time will expire. You can only perform 4 fleet missions at once. Mission types:

  • YELLOW - spy missions
  • BLUE - colonizer missions
  • GREEN - attack missions
  • GREY - fleet is returnig from the attack mission

Enemy Fleets - be prepare for the worse

After you discover Radiolocation Tech and build Radar, you can track enemy fleets movement. At the beginning of the game you will be informed about incoming assault only several seconds before attack. When you upgrade Radar, you will have ability to discover enemy attack incoming faster, having time to prepare your colony defenses. If you have spy bots, you can also get intel about fleet ships. Select enemy fleet and press A to send spy bot.

Shipyard - build your armada

If you build Shipyard, you will access shipyard building screen. Here you can build ships, transport and spy bots. Of course, you must meet resource, technology and shipyard level requirements to build selected ship. To build ships, just press HOME button and select required quantity by navigating arrows. If build marker will glow, the selected quantity can be build. Press A to build.

Intelligence - track your enemies progress

After building Intelligence, you can see intel about aliens progress. Ultimate weapon progress marker informs you about the enemy Solar Destroyer research progress. Each time you lost battle with enemy fleet, the marker will be increased. If it fills up, the aliens will start to send Solar Destroyer to attack your planet. Alien colonies marker informs you, how many planets are occupied by enemy forces. You must find and defeat all enemies garrisons in order to make final assault on the alien capital.

Fleet stats - inspect your forces

Here you can see all ships currently stationed at your colony and the current battle experience points.

Star Routes - oversee your transport routes

Here you can see currently established trade routes between you colonies.

Transfrom Resources - get needed supplies!

After building Transformer, you can access Transform screen. Here you will convert one type of resource to another. Just increase resource quantity by holding up arrow and press A to transofm.



Build ships to defend your Capital. Build Radar to track down enemy fleet and prepare for the attack. Build Planetary Defence system to destroy additional enemy ships. Build Warehouse to stash resources and protect them from pillaging.


Always observe enemy research progress. Make wise decisions when to attack and when to defend. Progress bar will increase after each succesfull raid on your capital. If progress bar will fill up, enemy will send ultimate weapon to destroy your Capital!


Upgrade Power Plant and mines in order to increase resource extraction. Set trade routes to get additional resources from the colonies. Finally, build Logistic Centre to increase trade routes capacity.

Release Notes:

The game doesn’t have save option. On the tests game was finished within 2 h. Game has a lot of variables so i’ve decided not to save them all into folder, because loading operation would last too long. In the game options only one enemy can be selected now, but in the future there will be option to select 2 enemies.

Hi great, good idea and great job.
I hope you’ll be able to continue it and perfect it again.
Maybe you could add more time to construct buidings / ships and maybe space moe the attacks mainly at start. Else, it’s one strategic game, yes they ae so few… it’s need so many works to do one adjust all asw… You’re crazy and i like crazy people. Thanks alot for this game and your work

Thx for feedback. The game is not completed yet. I must add second oponent to choose. Then the player will have to destroy 10 colonies and destroy 2 capitals instead of one. Enemy will send up to 4 fleets to attack player. Also needed to add at least some base sounds to the game.

About building time and reasearch time - I was thinking about that. But the main problem would be, that the game would last too long to complete in one session - and without save game (if for example gamebuino will run low on the battery) all progress will be lost.

I will also plan some upgrades (in the free time) - add new techs, building, maybe some other ships. Everything depends from community feedback :slight_smile:

Wishing high score from one session. :slight_smile:

Yes, and add an autosave would be great (you could aggregate many variables in one for exemple using bits position (Some var comme maybe be between 0 to 15 (for building levels for example, you will be able to save 8 in a 32 bits integer… depending of how many buidings you have, it’s can only take one or two 32bits or 64bits variables. You’ll have to do for all the var, but it’s can take only some values to save / load and after, they could be splitting in the good variables to save / restore the game value an let the user retrieve his game. I was talking of an autosave as in these conditons, game could do a save the state of the game at each turn. So game could be as complexe as you want and player would not have to restart all from scratch in case of bug or bad action from his part.
It’s could be cool that player have one to 3 slots to make his own save (I think that one could be enough in addition of the auto save).
Good luck for dev.

Maybe you could replace the circle in front of the counter of ressources by first letter: M for Metal, C for Crystal and F for Fuel, too ?

Yep. I can do that for more clarity. maybe also add one more 0 to increase max resource capacity. We will see.

trés bon jeu

Merci :smiley: It is not complete yet. I must implement save game, so you can pause anytime you want (developing it right now). And of course add some additional buildings and tech :slight_smile: Thx for vote.
