The game's "Ventara Mode" is a series of missions where you fight Advent Beasts and other Kamen Riders, with a chance of unlocking them (as well as more Advent Cards) in a certain mission. Xaviax is the final boss and has a different ending for each of the playable Riders except for Wrath who fights Dragon Knight as the final boss due to Wrath being possessed by Xaviax as in the show. Xaviax himself becomes a playable character in "Duel Mode" once all 13 Riders are unlocked and the player has defeated every mission (including defeating Xaviax himself) available in the "Ventara Mode" for each Rider.
