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?

“If you're not a sandbox fan or are not interested in getting involved into the development of Avorion, you should probably wait for the full release estimated in Q3 2017.

Avorion already has a lot of features, but it's still lacking some content. We have many more features and, above all, content in mind which still needs implementing. We want to flesh out the storyline, add more missions and give players more options of what they can do.

To achieve all that we want to involve the community in the development of Avorion, working closely together with you during the remaining development time. This means that we want to collect feedback from you guys, to help us create a great and unique sandbox experience!”

Approximately how long will this game be in Early Access?

“We're planning a period of about 6 - 12 months.”

How is the full version planned to differ from the Early Access version?

“Avorion is already rather far in development and already has a lot of features, but it's still lacking some content and things to do, such as missions. The full version will have more features, weapons, blocks, side missions, a more fleshed out story, more bosses, more goals you can pursue.”

What is the current state of the Early Access version?

“Right now we have the basic parts of the game up and running, and have started building upon them. There are first events, a story line and boss fights. To keep it simple, here are the most important features:

  • Procedural Galaxy, Factions, Ships and Space Stations
  • Co-op Multiplayer
  • Ship Building with various Materials and Blocks
  • Space Combat with large Battles, fully destructible Ships, Loot and Boss Fights
  • Dozens of different Weapons and Upgrades
  • Dynamic Trade System including Smuggling
  • Storyline serving as a driving factor to discover the game
  • Day 1 Modding Support

The engine and basic game systems are standing and we will now start building the remaining content based on that.”

Will the game be priced differently during and after Early Access?

“Yes, we want to encourage people to join us during the Early Access period, so the price of the Early Access version is lower than the final version.”

How are you planning on involving the Community in your development process?

“We want to work closely with the community to make sure the game will be in the best possible state. We have ingame means where you can easily submit bugs or feedback.
Those who have been following the game for a while now know that we're very responsive and have been working with the community since the very beginning. We've always taken your feedback to heart (be it positive or negative) and we have no intention of changing that.”

The Alliances Update is now live!

The Alliances update is now officially live! We've worked hard on this update and we hope you'll enjoy it.

Warning: Backup your savegame!
We have had several incidents reported where the update may have broken savegames. It is strongly recommended to make a backup of your current saves.

Please report these incidents in the forums and supply your old galaxy so we can see what's going wrong.

Alliances and Co-op Flying

Gather your friends to form an alliance and discover the galaxy together as your own faction sharing ships, resources and map knowledge!

Fly ships together in co-op mode: Have one friend be the pilot, another one be the gunner and a third one responsible for energy systems and fighter squadrons!

Steam Workshop Support

Download ships from the Steam Workshop and upload your own creations so everybody can use them!

Improved Building Mode

With the new building improvements you can now hide blocks, scale ships or mirror across several different axes.

Out Of Sector Simulation And More
Alliances are not the only new feature that is now available in the Alliances Update:
  • Full out-of-sector simulation of stations and ships
  • Pilot ships with your friends
  • Upload your latest creations to the Steam Workshop
  • Subscribe to hundreds of Workshop ships built by the community

Alliances Update Final Patchnotes

Hey guys,

These are the patch notes for the upcoming update! We'll set the update live during the next 24 hours.

We've had a nice long testing period on the beta branch and we feel that the update is now stable enough to be released on the default branch.

Should you run into any problems loading your old saves, please tell us immediately so we can fix it! We recommend making a backup of your saves though, just in case.

We're also going to go back to smaller updates. We've released this update as a huge chunk of work and we're really happy about it, because we feel like these new contents worked well together.
But we feel like releasing smaller updates in quicker succession is the better way to go. Large updates are hard to predict, which is already hard in software development, and we failed at making a clear timeline for this update. The size of this update was an experiment and we've come to realize that we and the community both prefer smaller and more regular updates.

We will be posting a roadmap of what's planned for the future soon.

  • Players can now found alliances
  • Invite other players to join your alliance
  • Alliances work like their own factions: They have money, resources and an inventory
  • Players can be assigned ranks, defining permissions in the alliance
  • All alliance members are visible to all other alliance members on the map
  • Alliance members share all information on the galaxy map
  • While flying an alliance ship, all actions represent the player's alliance
Co-Op Flying
  • Alliance ships can now be flown by multiple players
  • Added Seat Management for crafts to allow players to manage different tasks (steering, firing, etc.)
Out-of-sector simulation
"We'll be adding some more means for better control of which sectors will actually get updated on multiplayer servers. For now, sectors with lots of stuff will have a higher priority."
  • Sectors with player and alliance content are updated while the player is not inside the sector
  • Default amount of updated sectors per player on multiplayer is 6 (the sector the player is in, plus 5)
    • This value can be configured in the server.ini settings and will be a lot higher for singleplayer
  • If a player has property in more than 6 sectors, this happens:
    • Each sector will have a priority score
    • The 5 sectors with the highest scores will be updated
    • The score in the sectors is 3 for each player station, plus 1 for each player ship
Steam Workshop
  • Steam Workshop integration for ship and station models is complete
  • Saved ship plans can now be uploaded to the Steam Workshop
  • Subscribe to ship plans on the Steam Workshop
  • Added a new flight recorder block
    • Flight recorders will mark the death location of the ship on the map
    • Flight recorders will only work if they're *still on the ship* when the ship is destroyed
  • Trading posts always have dedicated cargo storage
  • Added licenses for stolen, dangerous and illegal cargo transportation
  • Added multiple mirror planes in building mode
  • Removed randomized building mode
  • Implemented whole ship modification
    • Scaling entire ships
    • Upgrading the material of entire ships
    • Rotating entire ships
  • Added selective block modification
    • All but one material or block type are faded out
  • Added a search field on the galaxy map
  • Turret factories sell a random, more expensive selection of the goods they require for building turrets
  • New Turret: Pulse Cannon
    • Pulse Cannons shoot ionized projectiles that have a very high chance of penetrating shields
  • Added respawning of resource-asteroids in sectors with large asteroid fields (will only be in effect for new sectors)
  • Removed collaboration component since Alliances replace this functionality
  • Added experimental backwards compatibility for saves created in the beta branch
    • A backup of the sector file will be created before converting, so no data will be lost if the conversion fails
    • Please report conversion errors in the forum or via the bugtracker so we can fix them!
  • Independent turrets now get their targets assigned by the server and no longer search them on the client
  • Mining and Salvaging AI commands now no longer continue when there was a player entering the ship
"We're currently working on making shields less powerful, and one of the means to do that will be adding more weapons that are strong against shields, such as pulse cannons. But we also felt that plasma cannons didn't have the impact on shields that they were supposed to have, so we upped their damage to shields."
  • Doubled shield damage of plasma guns
  • Reduced darkness of window shadows
  • Added a setting for limiting FPS
  • Improved rendering performance in sectors with lots of wreckages
  • Improved performance of inventory grid displayers
  • Added filtering for inventory grid displayers
  • Added favoriting of inventory items with right mouse

  • Added a message when changing control scheme
  • Improved german translation
  • Added a textbox to quickly transfer lots of cargo and crew
  • Trading routes tab is disabled when trading module doesn't support it
  • Added a Beta Branch notification when starting the game
"Most important changes here: Better performance on the server (memory and runtime) and improved savegame security."
  • Crafts that were destroyed through database corruptions can be restored
  • Players can be moved to other sectors, including ships (just rename the files if the names clash)
  • Player & Alliance files are saved redundantly to avoid loss of data on file corruptions
  • Improved performance when players log in
  • Improved overall networking performance
  • Improved overall memory performance using lazy initialization of collision data
  • Improved performance of traders in sectors without players
  • Added detailed output about script memory usage to /status command
  • Sector content is now compressed before being sent, reducing traffic when changing sectors by 70%
  • Server files are now compressed
  • Implemented whitelisting of steam groups
    • There's a separate file group-whitelist.txt in the server folder where you can add 64bit steam group ids that should be whitelisted
  • Improved traffic for normal sectors with players
  • Improved performance for sectors without players
  • Added more tracing and logging to server startup sequence
  • Added a time counter for online time of server
  • Fixed a major performance issue for armed ships near the barrier and the center of the galaxy
    • Large AI ships in the center of the galaxy no longer spawn with 50+ turrets
    • These ships now have less turrets but the turrets deal more damage so the lesser turrets are compensated
Scripting API
  • Entity IDs are now 128bit UUIDs
  • Script memory footprint reduced
    • Scripts that are attached to the same object are loaded into the same lua VM, if possible, to reduce redundant data
    • Added namespaces so scripts can be distinguished from each other and to avoid name collisions and functions getting overridden
    • Scripts that have DIFFERENT namespaces will be loaded into the SAME lua VM, since name collisions aren't expected to happen
    • Scripts that share the SAME namespace will be loaded into DIFFERENT lua VMs
    • Scripts that have a namespace must have a comment '-- namespace NAMESPACE' where NAMESPACE is the script's namespace
    • Scripts that have a namespace must have a namespace table with the same name as stated in the namespace comment
    • Scripts that have a namespace comment must prefix all non-local functions and variables with their Namespace table (see scripts for more details on this)
    • Scripts that have no namespace comment statement will always be loaded into different VMs (which is exactly the old model)
    • It is STRONGLY recommended to modders that they rework their scripts to use namespaces to save memory performance!
  • Lua VMs aren't set to invalid after a normal error, but still on fatal errors (exceptions)
  • [Documentation] Fixed methods of inherited script classes not showing up in completion docs

About This Game

Avorion is currently in Early Access, and under active development. If you want to know more about that, please read the Early Access disclaimer at the top of the page.

Several hundred years ago, a cataclysmic catastrophe nearly ripped your galaxy apart - an insurmountable ring of torn hyperspace fabric appeared in the center of the galaxy, which normal hyperspace engines can’t overcome.

Since this event nobody has managed to get near the central regions of the galaxy. All you know is that this event also spawned multiple insurmountable hyperspace rifts throughout the entire galaxy, and that a strange race of aliens, the Xsotan, has appeared in the center. It looks like these aliens have found a way to surpass the torn hyperspace fabric, but so far nobody has managed to establish contact with them.

There are also rumors about a strange new metal called ‘Avorion’, which has appeared in the center of the galaxy, around the same time as the Xsotan arrived. Apparently the aliens use this material to build their ships.

Start out as a nobody at the edge of the galaxy and work your way to the center of a galaxy that gets more dangerous, but also more rewarding the closer you get to its core. Avorion takes sandbox aspects from games like X or Freelancer, throws in co-op multiplayer and lets you build your own ships. It features ships made of freely scalable blocks that can be procedurally generated and that break into pieces where they're hit in space fights.


Equip your ship with chainguns, lasers and other weaponry to take on your enemies and enjoy the sight of completely destructible ships breaking at the exact points where you hit them. Defend your allies from pirates, hunt down enemies for coin or even participate in wars between entire factions. Build hangars and command squads of fighters in your battles or destroy enemy freighters to steal their cargo.


Fly through beautiful nebulas and dense asteroid fields in search of hidden treasures and meet the many factions that populate and control their portion of the galaxy. Each faction has its own characteristics, such as peaceful, intelligent or aggressive, and has its own ship styles, meaning their ships and stations have a distinct look.

Explore the galaxy at your own pace to find valuable goods in old ship wreckages, undiscovered asteroid fields rich of resources, unchartered asteroids which you can claim for yourself, or clues as to what happened during the event a few hundred years back.

Build Your Fleet

There are no limits to ship size or complexity besides your resources. You're not bound to the standard voxel style and while building an awesome ship in Avorion you won't get lost in lots and lots of micro-management. You can focus on building a great looking ship, without having too much trouble to make it work. But make sure you still keep an eye on your ship’s maneuverability and energy requirements. Adjust your ships perfectly to their operational purpose by building light and agile or heavily armored ships.

Build specialized transport ships with lots of cargo space or heavily armored battleships with strong shields. Collect loot from defeated foes which you can use to upgrade your ship: New turrets, resources, trading goods or system upgrades. Install system upgrades that allow more weapons, ease asteroid mining or trading systems which detect trading routes over multiple sectors.

And why build only one ship? Hire captains to fly your ships for you, manage your crews, weapons, hangars and fighters and build your own fleet of space ships!


Extend your ship with a cargo bay, find profitable deals and haul over a hundred trading goods through the galaxy to make a profit and buy your way up the food chain: Build up a trading corporation and extend your influence in the galaxy by founding asteroid mines and factories that attract NPC traders who will buy and sell their goods at your establishments.

Co-op Multiplayer

You don't have to fight the galaxy alone! Avorion features co-op multiplayer, so team up with your friends to build stations together and destroy pirates and enemy factions! Work together to extend your influence in the galaxy and build your own empire. Or, you know, blow them apart in large PvP battles. It's a sandbox, you can do whatever you want.

In Avorion you choose your personal playstyle. Haul cargo, find profitable trading routes and found factories. Or maybe you're sick of being the good guy? Build your own battleship, equip it with powerful weaponry and blow away your enemies. Be the aggressor that starts wars with entire factions, raid freighters, smuggle illegal goods and scavenge old wreckages. Find your way to the center of a galaxy that gets more hostile, but also more rewarding the closer you get to its core.
