A pre-alpha gaming operating system pairing a controller-first console mode with a full KDE Plasma desktop.

Landing page captured for the 2026-08-31 issue.

Why it surfaced

Castalia GOS treats the operating system as part of the gaming experience: updates are atomic, bad releases can roll back with one click, and its Bru mascot guides the setup. It is not installable yet, but the project already states its limits plainly—including the fact that kernel-level anti-cheat games will not run.
