MU Online for Linux

No Wine, Lutris or PlayOnLinux: on OpenMU, MU Online Season 6 runs right in your distribution's browser.

Why regular MU is a hassle on Linux

✕MU Online clients are built for Windows (.exe).
✕Running them through Wine, Lutris or Proton needs configuration and does not always work.
✕Server anti-hacks often block or freeze on Wine.
✕Each client update can break the setup again.

How OpenMU solves it

The OpenMU client runs in the browser (WebGL 2): you open the site, sign in with your account and play the full Season 6, with every class, events, reset and ranking. Nothing to install on the system.
