Helion: A modern fast paced Doom FPS engine in C#

Summary

The latest stable release for Windows and most Linux distros can be downloaded here. Nightly experimental builds are also available here for users who want to test the latest features before they’re ready. Helion uses .NET 9. The self-contained Helion releases include it, otherwise Windows users will need to install the Desktop Runtime, and Linux users will need to follow the instructions for their distro. On Linux, you will also need to make sure OpenAL, libsndfile, and libmpg123 are installed. For information on setting up and playing, see the bundled game documentation.
