Wish there was a mixed recommendation on steam for reviews like this but this is definitely the weakest DLC out of the batch for F/SR. It's just too predictable and doesn't really have the most compelling story. I was hoping that Munenori and Musashi would have some more added depth here dialogue and story wise. Munenori as a unit isn't that interesting either after coming off of DLC 1. Story is kind of boring and honestly feels like the type of thing you'd be perfectly fine skipping all the cut-scenes for and STILL get the gist of what's happening around you.
For the price there's honestly little addition to the base game even on a steep sale like the Winter Sale. It should have been a free download. I can only recommend it for Munenori super fans and even then you're kind of getting a nothing burger.
