Treason Update #11 (12.12.2025)

The final update of this year. Welcome to Treason Update #11! Without further ado, let's get right into it.

The highlight of this update is native Linux support. We have ported Treason to Linux, which was quite more complicated than just hitting "compile" on the source code. Be warned, if you had Treason installed before with the Windows build on your Linux machine, you MUST uninstall the game completely and reinstall it again, because of capitalization issues with our assets that Steam does not fix with an update, only with a full reinstall. Can't do anything about that, sorry!

The rest of the update was focused on implementing feedback from you, our community, after a very complicated update #10, which took a lot of our time. Thank you for helping us shape the game to make it better! We promise to keep updating the game with more exciting stuff in 2026!

Full list of changes

Stability

• The game will now throw an error on startup if your hardware does not support Shader Model 2.0b. It wouldn't work regardless before this change, this is just making it clear as to why you might not be able to run it!
