A quick look at the new Fatal Fury direction
In a blog post for Playstation, Fatal Fury: City of the Wolves, director Hayato Konya and art director Yoichiro Soeda go into detail as to the new art and character direction for the game; what parts have been brought over from previous games and which ones have been tweaked to fit their vision.
Part of the post details the new Rev system, including the Rev Gauge. According to Konya, Rev-boosted skills, special moves, and Rev Accel moves will give players the ability to use super moves but not be limited to one single gauge and was inspired in part by Fatal Fury: Wild Ambition's Heat Gauge.
