This is Units Addon Mod v1.1 for Medieval 2 Total War. This mod is a companion set that will add an additional 64 units into the game.
Fantastic, finally, I have some regular infantry who don't use spears.
Good quality units that fit in well with the vanilla game. I would appreciate a version compatible with the Kingdoms Grand Campaign mod though as it would work well there too.
I figured out how to get it running on steam. Put "@medieval2.cfg" in the launch options. It looks pretty cool and varied. Blah blah blah extra words to reach the minimum character limit.
