He who brought Leggo My Myth (and its sequel) is behind yet another conversion for our beloved Myth II. Rohan MoR has declared that the MythWarrior plugin, which contains six new maps and a slew of new units, will be released this Saturday at The Mill. There is a MythWarrior website (which I haven't been able to connect to) and a promotional shot available at MacGamer.
Addendum: Rohan has uploaded the promotional images to Rampancy Hotline due to the server troubles of the MythWarrior site. You can find the images in the Myth Uploads folder.
