-Four attack button layout a la MVC2 again. LP, HP, LK, HK. Crouching HP is the universal launcher. The other two buttons are Switch and Infinity Stone. Both can be used whenever.
-Everybody can OTG now.
-DHC, washdashing, and Happy Birthdays are still around.
-Advancing guard reflects projectiles now!
-You can call in a character to break your opponent's combo by spending two meters.
