Following Breathrough at Mikatagahara, this is an alternate Nagashino battle. In the intro you'll notice that Huang Gai reacts to Kunoich with the exact same words Ma Dai does in the normal version, which is sort of funny.
The difference in this battle is that Guo Huai and Ranmaru aren't mind controlled and are holding up a resistance with Hideyoshi. Pretty fun stage, always love alternate takes and what ifs.
