Wow fail Story Mode. No Naruto,Bee and Itachi VS Nagato Sasuke VS Danzo Sasuke VS Kage Tobi VS Konan Kisame VS Bee
Wow only 1 boss fight in the Kage Summit and it's Naruto and Sasuke.
Just because something's not the focus of a chapter doesn't mean it isn't covered.
Umm they should still be Boss Battles.
A lot of time goes into the animating the QTEs and working a Boss Battle in general. Remember we now have Hack and Slash so for Sasuke v Kages it could be literally Sasuke vs All of the Kages at the same time.
