Samurai Warriors 3 - Mitsunari's Story 5 - Battle of Sekigahara

This Sekigahara is one of the harder ones, especially for the Western side of it. The fog is still an issue, but the real challenge comes when you have to face Tadakatsu and Kiyomasa at the same time. There's actually a unique in battle cutscene with Kiyomasa at the end here.
