Arena fighting where builds and combo execution meet light PvP prediction.

Execution · Competitive PvP
Substitution baiting against humans atop simple anime-fighter inputs and team picks.

Naruto Shippuden: Ultimate Ninja Storm 2
Timing substitutions and combos matters but inputs are simple
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
