Here's the press release, savagely abridged:

Creation is proud to announce the release of BUSHIDO: The Way of the Warrior, the most ambitious Total Conversion released to date. Taking place over the rich tapestry of the history and mythology of feudal Japan, BUSHIDO provides a new set of mortals, monsters, and magic for Myth II games and sets a new standard for ambience and unique gameplay in a Total Conversion.

The BUSHIDO tagset (11 megs), which is required for all maps, also allows one to convert regular Myth multiplayer and solo maps to BUSHIDO units. Tehajimeni and Sekando Bushido Map Packs (9 megs apiece) include all the maps you need for b.net fun and league play
