This mod is both a work-in-progress and a released one, so I'm going with the released prefix.
This guy, Ii Naomasa, is known as the Red Devil (although technically he wasn't the only one to bear the nickname).
This modification will bring numerous new units into the game, including Ii Naomasa, and a bunch of other units with the prefix "Red Devil". Naturally, they will have a red theme.
Here is what I have planned thus far. It will most likely be bigger, but this is what I have thought out for now.
Units:
-Ii Naomasa. Erwin Rommel noted there is a general unit variant based on Naomasa, so I will use that as the officer.
-Red Devil Ashigaru. They are the same as the Yari Ashigaru, however the front rank can fire a bow. Those bowmen have the same stats as the Bow Ashigaru. The base upkeep is around ~110 koku per turn. At the moment, the unit is recruitable by the Tokugawa in both custom battles and in the campaign. In the campaign, you should be able to recruit it immediately. The unit card is the same as the yari ashigaru, only I re-coloured the clothes red. (This unit is finished. There is a download link below.)
-Red Devil Samurai. They will be based on the Katana Samurai unit. I'm not sure if I will add the bow element.
-"Red Devil" themed cavalry units.
I would like a bit of help with this. Suggestions regarding features for prospective red devil units are very welcome, however I wouldn't mind having custom textures that have Naomasa's square(ish) crest instead of the vanilla circle on the ashigaru textures. I haven't mucked around with textures all that much, so it might be a while until I look at creating custom textures.
