Space Engineers

Welcome to the Space Engineers source code!

From this repository you can build Space Engineers. To play Space Engineers you need to own the game on Steam. Assets (audio, models, textures) are not included in this repository.

Before downloading the source code please read the EULA carefully - End User License Agreement.

See the Change log for latest changes.
Have you found a problem related to the source code? Report an Issue.
Discuss source code on our source code sub-forum.



Space Engineers must be installed on your computer, Steam must be running.

  • Clone or download and unpack the repository.
  • Open SpaceEngineers.sln in Visual Studio.
  • Open file global.props (it's in configuration folder).
  • Make sure ContentPath tag contains path to SpaceEngineers Content directory in Steam folder.
  • Start debugging by pressing F5 or select Debug - Start Debugging in main menu

Instead of modifying global.props, you can create user.props, more information here.

Common issues

Build error: The command "..\3rd\Utils\RunTemplate.bat "....\MyEnumToStringsGenerated"" exited with code 1. This is common when using old versions of Visual Studio, see Visual Studio support. It can also happen when TextTemplating.exe was not found for some reason (it should be installed with Visual Studio).

Assert: unable to find audio/model/texture file: 'xxxxxx'. This happens because repository is slightly ahead of content in Steam folder. Definitions (Content/Data) are taken from repository and may contain new definitions referencing assets which are not yet in Steam content folder. We decided to use definitions from repository by default, so you can easily modify it. You can edit global.props to use definitions from Steam (that should fix the issue). When running on Release asserts won't be shown; missing assets won't crash the game. More info here.

Where is the 64-bit version?

We're unable to provide a 64-bit version of all 3rd party libraries because of licensing. We're working on this and trying to negotiate a better license which will allow us to do that.
