Fighting with Kamen Riders and attempting to prevent the destruction of the worlds.
Combat in the game operates on a basic three-button system, encompassing Weak Attacks, Strong Attacks, and Special Attacks (such as the various Rider Kicks). In addition, many Riders have the ability to perform a Form Change once the Rider Gauge at the bottom of the screen fills by dealing or receiving damage, or by charging the meter.
Form Change can be used as a counterattack or to extend combos. A number of Riders also have the ability to summon Strikers, such as Ryukis Contract Monster Dragredder or Den-Os DenLiner. Also, each Rider has a unique finisher called Rider Finale. This attack can only be activated when the Rider Gauge is full and the R2 button is pressed.
