Empyrion - Galactic Survival is a 3D open world space sandbox survival adventure. Build mighty ships, menacing space stations and vast planetary settlements to explore, conquer or exploit a variety of different planets and the allegedly empty space! Fight human, alien and biological hazards and survive in a hostile galaxy full of hidden dangers - on your own or with your friends.

The game uniquely combines elements from space simulations, construction games, survival games and ego-shooters. Empyrion is currently under development by Eleon Game Studios.

Detailed Game Features:

Space and Planet Exploration:

An absolute free-roaming experience awaits you: warp between planets, fly from planet to moons, land on planets and freely walk around to explore your surroundings. Discover the secrets of the Aliens and tangle with the native fauna and flora. A sandbox full of different, vivid planets waiting for you to explore!



Solar System and Open World:

The solar system is procedurally generated and features several planets and POIs. Each planet has its own characteristics (planet type, gravity, atmosphere, number of moons, terrain, surface, vegetation, climate, and resources).


Building and Construction:

Build large capital vessels, small fighters or exceptional space and planetary bases by yourself - or download a blueprint from the Steam Workshop and customize it with your very own ideas of form and function!


Survival Mode:

Get out of your escape pod, grab what's left from your ship and prepare to survive in a hostile environment. Food and oxygen are rare, resources are scarce, ammo is low and dangers lurk around each and every corner. Keep your eyes open. You need to be well prepared if you want to survive more than a day on an alien planet far away from Earth.


Creative Mode:

Just build and make your crazy dreams come true, without having to bother with food, resources or enemies. Join the Creative Community and upload your creations to the Steam Workshop!


Singleplayer and Multiplayer

Play as a lone wolf in singleplayer or join the multiplayer community: Make yourself a comfortable home in a well-protected PvE area or pick up some friends, head out and beat the permanent dangers of PvP planets to ransack their riches or conquer the solar system with your faction.


Wildlife and Enemies:

Don't get mislead by the peaceful fauna of some planets and the silence in space. Most of the animal wildlife wants to snack on your leg - and aggressive robot drones, alien soldiers and their guardians will try to hunt you down as soon as you are within sight. Watch your six and deploy a range of weapons for your defence.

Mining and Resource Gathering:

For building and construction, you need to gather and mine resources. Dig down to the rich deposits of a planet or drill through an asteroid full of rare ore. You might also plunder alien buildings or scrap any structure you come across.


Extensive Crafting System:

Learn how to combine resources and building materials to craft your equipment. Craft your stuff in your base or while you are on the move and equip your buildings and vessels with a range of different devices, weapons and gadgets for different purposes.

Hunting, Farming and Food System:

Grow your own vegetables and fruits or hunt creatures for their meat to prepare yourself a delicious meal. Some plants help to create medical supplies while others can be picked up and consumed for first aid or to quickly settle your empty stomach.


Experience and Tech Tree:

Do whatever you want - and gain experience points for doing so! Scrap that old stuff and use the points to unlock those shiny new devices in the Techtree.


Terrain Deformation:

Each planet features a voxel-based terrain. You can entirely modify and deform the terrain: flatten it for your planetary station, dig holes to find resources or build a tunnel system to protect yourself. Empyrion is a true sandbox game!

Hi Galactic Survivalists!

After a lively Experimental phase (thanks for all your feedback!), we are excited to release a quite substantial update just before Christmas: Alpha 7.5 is out now!

For those who did not follow the Experimental phase, a few quick notes. Everyone else, feel free to skip the next paraphs and scroll down to the full changelog...but please do not forget to VOTE for us in the second stage of the INDIE of The Year Awards 2017.

Thanks to you support, Empyrion made it in the first stage to the TOP 100 and now the crucial phase begins to determine the overall winner for 2017. We have tough competitors in the category "Futuristic Sim" (Rimworld, Space Engineers, Planet Nomads and Cosmoteer). Every vote counts:

Why did we skip version 7.4? Because the current version will not only add bugfixes or a few changes, like the second step of the ammo rebalancing (bringing the materials used more in line with the type and damage values of the weapon), but also adds a few completely new features: Solar Energy, Sell-to-Trader and O2-conserving force fields! This alone deserves the honorable .5 version tag! :)

And that’s not all: because we want to open up the game beyond choosing the difficulty settings at game start, Alpha 7.5 will add a new config file, which will allow you to change all relevant parameters for almost all blocks/items/templates/entities used in the game!

Apart from the new features and mechanics, we added a lot of new and updated models - from ATM up to our new Zirax warriors - rebalanced even more templates, and made a lot of other changes as well.

Please find all changes and additions in the changelog below.

As a side note, if you want to know more about the Zirax and some of the other factions, visit our new FACTIONS OF EMPYRION overview: Empyriongame.com

Now, have fun playing and do not forget to pick up some delicious Akua Sparkling Wine (demi-sec, Class 2480) for your christmas and end-of-year celebrations ;-)


Empyrion Dev team

- Please report bugs and issues right here: Empyriononline.com
- Our Feature Survey 2018 is still active and can be voted here: <
- As announced, we will wipe ALL of our official servers with the release of the public version of Alpha 7.5: Empyriononline.com


Changelog: Alpha 7.5.0 (Build 1416)

Solar Panels:

- Added solar panels (horizontal and sloped)
- Added capacitor (solar) to manage the electricity of the solar panels and store the electrical energy for use during the night or bad weather
- Solar panels & capacitor (solar) are currently only usable for bases (Space and planet)

IMPORTANT FEEDBACK QUESTION: Do you think the solar panels are currently too weak? We can easily re-calibrate them - it is important to find a good default energy output.

FEEDBACK & DISCUSSION: Empyriononline.com

How Solar Energy works:

- The algorithm calculates the amount of sun-rays that will hit the solar panel for a certain placement during the day. The placement affects their efficiency (see factors listed below)
- This average efficiency is then displayed by the GREEN LCDs (up to four LED lights)
- The current efficiency is displayed by the YELLOW LEDs (up to four LED lights)
- If solar panels produce more electricity than currently needed, the surplus energy is stored in the Capacitor (Solar) block like in a battery.
- To display the surplus of energy (or the “energy reserve”), there is now a battery icon in the main page of Control Panel that shows the current content of the battery.
- Note: conventional generators (fuel driven) do not store excess power in the battery!

Factors that will increase or reduce the efficiency on a PLANET:

- Placement behind an obstacle (tree, stone, base, mountain etc) leads to a reduced efficiency
- Stronger Light Intensity on the playfield increases efficiency on a global scale (parameter: DayLightIntensity in playfield.yaml).
- Light Intensities overall impact on the efficiency is influenced by the weather condition in a second step: eg when it is cloudy or raining, light intensity effect decreases and thus also efficiency of panel
- Angle of panel towards sun: best efficiency when sun hits perpendicular on panel (eg on equator a flat solar panel lying on ground will have highest efficiency at noon, while a sloped solar panel close to pole while be better)
- AtmosphereDensity: higher density = less overall efficiency
- AtmosphereDensity is modified by latitude! Example: If the position of the Solar Panel is closer to the poles, it is less efficient for the same AtmosphereDensity factor, because sun travels through more atmosphere than on equator.
- Ground fog reduces efficiency

Factors that will increase or reduce the efficiency in SPACE:

- Angle of panel towards sun: best efficiency when sun hits perpendicular on panel
- Distance of sun: the further the orbit playfield is away from sun, the lower the efficiency (eg lower efficiency in Ningues orbit than Aestus orbit)


- Added possibility to sell items to Trader NPC
- Added simple price dynamics depending on items in stock of trader. (eg. price will drop if you repeatedly sell items to the trader. Price will rise if you repeatedly buy from a trader)
- Updated TraderNPCConfig.ecf:
* Adjusted all prices for Ore, Ingots, Weapons and Tools
* Added Magnesium, Plastic and Nitrocellulose to all weapon and resource traders
* Reduced price for Boosters and other Equipment
* Reduced price for most of the Food and Health items
* Selling/Purchase prices are more dynamic (min-max ranges)

Better Modding Support:
- We added a config file that allows you to change all relevant parameters for almost all blocks/items/templates/entities used in the game. For example, you can change the damage value of the minigun etc. We will provide more detailed information about the parameters soon.
- The config file can be found here:
...\Steam\steamapps\common\Empyrion - Galactic Survival\Content\Configuration\Config_Example.ecf
- To activate it, rename Config_Example.ecf into Config.ecf.
Please note: the config currently cannot be included in a scenario, but needs to be placed in the main folder as described.
FEEDBACK & DISCUSSION: Empyriononline.com

Added Airtight Force Fields:

- We added airtight force fields in different sizes
- The force fields keep O2 inside your base. They do not work as a hitpoint barrier (planned for a future iteration)

Sync of Playfield Instances:
- The new Instance Sync gives you a better possibility to create very unique and complex instances / missions since the portals are now synced over the network and not local anymore.
- For example, you can now point two individual portals from different planets to one instance (not possible before). That way two Origins can try to compete against each other and return to their planets independently.

Improved Difficulty Settings:

- Added food and oxygen consumption speed to difficulty settings (SP, dedi and local coop): you can now even disable food and oxygen consumption
- Tweaked difficulty window layout


- Added Christmas Tree (can be found under “Artificial Plants (Deco)”)

- Added “Akua Sparkling Wine, demi-sec, Class 2480” (also in start equipment SP; available from traders of Market Cafe, bars and all food-selling places)
- Added new model for Zirax NPC (with size and style variations)

- Added new model for SciFi-style Bunk Bed (can be found under “Furnishings (Deco)”)

- Added new logo (Earth faction) to symbols
- Added single and double corner lights

Added Alternative Terrains:

- We added alternative terrains for most of the handmade planets (e.g. NewAlien_V2, NewLava_V2, NewDesert_V2, NewTemperate_V2, NewMoon_V2, NewMoon2_V2, NewBarren_V2, NewDesert2_V2, NewSnow_V2, NewOcean_V2).
- These V2 terrains are activated when choosing odd-numbered seeds

Visuals / Audio:
- Updated models for trading station and ATM

- Better screen textures for Cockpit CV, Open Cockpit SV and some console blocks
- Added new particle effect for NPC crew destruction
- Updated model for corn dog + added proper harvest stage for snow version
- Tweaked position of all space playfields in default SP and MP (moved all space playfields down by 100 sectors so that playfields are below sun, ie sun will shine from above for better visuals)
- Added more ambient music (Resurgence, Reaver, Adrift, 2473): Thanks to Alex


- More size variations for Golems (Ice, Swamp, Desert)
- Added better sound when opening PDA
- Better default color for open cockpits
- Tweaked glass on Clone Chamber and Medic Station

- Allow to promote Member or Admin to Founder if old Founder has left the faction
- Added Fiber to templates (made from Wood Logs)
- Added Nitrocellulose (made from Fiber; used as a propellant for any bullet/projectile-driven ammo, instead of Promethium)
- Added magnesium deposits to Moon playfields (SP and MP)
- Added pentaxid asteroid to space playfields: Trading Station and Asteroid Field
- Slightly brighter nights on planets
- HUD names show allied structures of other factions now in green
- Automatic Door blocks are now craftable in Survival Constructor
- Added 30 Unlock points

Template Re-balancing:
- Capacitor Device: Removed Flux Coil, Reduced Oscillator and Steel Plates
- Color / Texture / Multi Tool: Removed Mechanical Components
- Laser Rifle: Reduced PowerCoil
- Plasma Cannon: Reduced Oscillator, Zascosium Alloy
- Moved tech level of Small Generator and Fuel Tank (T1) to level 3
- Adjusted templates of fuel tanks (BA, CV) and generators (BA, CV) to better reflect the technical progression/increasing capabilities


- Removed Promethium from all bullet/projectile ammo; added Nitrocellulose as a propellant instead
- Small-to-mid-size caliber (handheld weapon) ammo templates now made from a mix of copper, steel, plastic and Nitrocellulose (Pistol Round, Rifle Round, Shotgun Shell, Sniper Rifle Round, Minigun Round)
- All rocket ammo needs Magnesium Powder
- All laser- and plasma-based ammo is made from Pentaxid and Plastic
- Output of most ammo types has been adjusted, based on the overall availability/scarcity of the used materials and the changed templates

GUI Improvements:
- Added "Back" button (Disconnect from Server and go back to Server Browser)
- Added “Back” arrow button to starter planet selection to toggle starter planets back and forth
- Some layout tweaks to windows "Choose Starting Planet" and "New Game"
- Do not display "Output Count" in item trader info anymore
- PDA message boxes can now also be closed via ESC key
- Corrupt save games are now displayed in red to quickly find them in the list of save games
- Head shot multiplier are displayed again

Other Changes:

Empyrion is ok, I just wish the art in game did not look like mash up. I heard they got their textures off deviant art and that they do not have artists working on the game. That is a turn off for me.

I've gotten less sleep since discovering this game a few years ago, it's that good.

Wonderful game! Keep up the good work!


There is some procedural generation. With the current version, though, they're experimenting with image maps for planet surfaces. But it does sound like they plan to implement improved procedural generation down the road.
