Play MU Online on Steam Deck

UnrealMu is a free Season 6 Episode 3 MU Online server with three realms (Hard 5x, Classic 100x and Fast 1000x). The Steam Deck runs desktop Linux on a 64-bit PC processor, so there are two good ways to play: in the browser, or with the native Linux client. Your account and characters are the same on every device.

Option 1: Play in the browser (quickest)

1. Hold the power button and choose Switch to Desktop.
2. Open a browser (Firefox or Chrome from the Discover store).
3. Create your account, then open the browser client and pick a realm.
4. The first load downloads the game data and keeps it cached for next time. It needs WebGL 2, which the Deck provides.

Option 2: Use the Linux client

1. In Desktop Mode, open the downloads page and get the full Linux client. It already includes music and sound.
2. Extract the archive and run Play.command. After this first install the launcher updates itself.
3. The client needs desktop OpenGL, GLEW and libturbojpeg. If a library is missing, install it for your system or use the browser instead.

Add it to Game Mode

In Desktop Mode open Steam, choose Add a Game, Add a Non-Steam Game, and add your browser or the Linux client. It then appears in your library and starts from Game Mode.

Controls on the Steam Deck

• Use the right trackpad as the mouse, and map a trigger to right-click. Skills such as Triple Shot are cast with the right mouse button.
• Bind + and - (camera zoom) and the F keys to buttons in your Steam Input layout.
• Use the on-screen keyboard (Steam + X) for chat.
