There's a new Japanese warfare themed map & unit set at the tain.
"Sengoku is a 16th century Japanese warfare conversion for multiplayer which includes a unit set and some multiplayer maps with these units. Sengoku is heavily based on Bushido and Assassin!, but the gameplay and units are substantially different and more complex than in either. It is my first Myth project, and took 2.5 years of work to complete.
The title "Sengoku" refers to the Sengoku Jidai(1460s -1610s), the Warring States Period in medieval Japan. Sengoku features many gunpowder units not available in Bushido, and attempts to simulate actual tactics of this time. The armies are massive, the fighting is fast-paced and vicious. I would recommend looking over the readme file before attempting to play this."
IN case there's any confusion- _I_ am not the author of this medieval Japanese plugin. I am just the bearer of news.
