Avorion Demo

64bit Windows Demo

64bit Ubuntu Linux Demo

The demo is a remnant of the early development of Avorion before the Steam release. This version (Avorion Version v0.8.5) dates back to the Kickstarter campaign. It has been left here for nostalgic reasons and because it offers a first glimpse into the basic game play of Avorion but it does not represent the full scope of the game. The Steam release into Early Access was Avorion Version v0.10 and several major updates have been added since then. If you are looking to see where the game is currently at, watching a recent stream or browsing the forum may be more helpful.

  • Ship Building Mode (but not all blocks and no custom turrets)
  • Creative Mode
  • Super Action Mode
  • Combat and NPC pirate attacks
  • Multiplayer

The game consists of a client and a server, and as the singleplayer starts a local server and connects to it, don't be surprised when it asks you to grant "AvorionServer.exe" access to the network.

Some Common Issues:

"Error starting Singleplayer"

Your virus scanner might be blocking/deleting AvorionServer.exe. To resolve this, add the AvorionDemo installation folder to your virus software's exceptions and reinstall the game into that folder.

"This Server Is Private"

1. Make sure that AvorionServer.exe is NOT running (kill it with task manager or reboot)
2. In the game settings, change your player name to a name that is accepted by the game
3. Delete all your galaxies
4. Start a new galaxy (at this point it should work)
5. If you get the error again, exit the game, make sure to kill AvorionServer.exe again
6. After you're absolutely sure that no more Avorion or AvorionServer is running, go to the Troubleshooting Board and post your issue there, including all the logfiles. See this thread on how to find your logfiles. We respond in a matter of hours if we're not sleeping.


Should you run into trouble installing Avorion on linux, then check this article in the Wiki. Avorion is officially only for Ubuntu Linux, but it's definitely possible to install it on other distributions, too.

These are unfinished beta versions, work in progress. They might and will most certainly contain bugs.
Please tell us about the bugs so we can get rid of them.
