Quoted from the Project Magma site about the new Myth2 update for Linux.

Project Magma is proud to announce the release of Myth II 1.7.2 for Linux.

No longer will Linux players have to resort to using Wine or booting into Windows to take advantage of the latest improvements to Myth II or to play online with other players. Instead, they can now enjoy the same native Myth II experience alongside existing Windows and Mac players of the game.

The Linux release of Myth II 1.7.2 is fully compatible with Myth II 1.7.2 on other platforms, allowing it to run the latest plugins available on The Tain and to play online on Mariusnet.

Download the Myth II 1.7.2 Linux Installer or the Linux Demo today. The Myth II 1.7.2 Linux installer can be used to upgrade an existing Myth II installation or to install the updated version directly using an original Myth II CD.

Going forward, we expect future updates to the game to be released on all three platforms simultaneously.
