In Decade Mode, the player follows Tsukasa Kadoya's journey through the nine Heisei Kamen Rider worlds as Kamen Rider Decade, fighting the other Riders and attempting to prevent the destruction of the worlds.
This attack can only be activated when the Rider Gauge is full, and can be activated by pressing the R2 button. Also, each Rider has a unique finisher called Rider Finale. A number of Riders also have the ability to summon Strikers, such as Ryuki's Contract Monster Dragredder or Den-O's DenLiner. Form Change can be used as a counter or to extend combos. In addition to this, each Rider has the ability to perform a Form Change once the Rider Gauge at the bottom of the screen fills, whether by dealing or receiving damage or by charging the meter. Combat in the game operates on a basic three-button system, encompassing Weak Attack, Strong Attack, and Special Attacks (such as the various Rider Kicks).
