Ragnarok Mode

Ragnarok Mode starts with either OOO or W; the other is not obtainable in the file that you play (there are three files to save in).

Scattered along the maps of Ragnarok Mode are other Kamen Riders: add more Riders to your roster by either just adding them, having to fight them first, or by completing a beat-up round while protecting them. After each stage, you can unlock a Rider’s form for use anywhere in the game, or unlock them for the other mode’s rosters. But, certain Riders will disappear during Ragnarok Mode’s plot. You can take one other Rider (two starting from Stage 7), to swap with between battles.
