And here's a bonus article I'd like to share with GB.
* Boss matches can go in this order, Billy Kane, Ash, Saiki, and final boss (can't give away who it is)
** Teams can be freely selected in arcade mode, but in story you are set by a pre-set list of teams only.
*** Billy and Saiki are unlockable, but you must meet requirements. Ash is there from the start. (not sure which team could be on his side?)
**** Is there a special team? So far from other community sites it is unknown right now.
+ Gallery mode has a ton of hidden features, from art, to story mode cutscenes, and bonus videos. The more you play, the more items you unlock!
++ Customize is optional, depending on how many times you play a specific team or character. Plus Mission mode gives you rewards to your character of choice.
+++ Online mode works alright, its still undergoing some tweaking. But give it a try!
That's all for now! Au revoir
