Kamen Rider Chronicle

Kamen Rider Chronicle is an augmented-reality video game produced by the Genm Corp and distributed as a Rider Gashat. Its true purpose is to serve as a tool to control humanity by trapping people within it.

Gameplay
Players use the Kamen Rider Chronicle Gashat to transform into "Ride-Players" to fight Bugster bosses in order to claim their Gashatrophies. Anyone who collects all the Gashatrophies will be given the power to transform into "Kamen Rider Cronus" and fight and defeat the final boss, Gamedeus.

History
Development of Kamen Rider Chronicle was initiated by Masamune Dan, who secretly intended to use it as a tool to control humanity. However, after Masamune was framed by his son Kuroto Dan for causing Zero Day (which Kuroto had in fact actually caused) Masamune accepted the blame and allowed himself to be sent to prison in order to absolve him of guilt for the events that would follow.

Kuroto Dan then seized control of Genm Corp and the development of Kamen Rider Chronicle, intending to use it as a way to have humans fight against Bugsters for eternity as a testament to his genius and, secretly, as a means to resurrect his deceased mother, Sakurako Dan, who had perished after being infected with the Bugster virus.

After Dan was betrayed and killed by Parado, the Bugsters themselves took control of Genm Corp and Kamen Rider Chronicle, plotting to use the game as a way to genocide humanity as revenge for creating game characters whose only purpose was to get beat up. However, the Bugsters soon lost control of the game when Masamune Dan was released from prison after being acquitted for causing Zero Day, obtained the powers of Kamen Rider Cronus and took back his company, revealing himself as the true mastermind behind Kamen Rider Chronicle and reverting the game to its original purpose of being used to control humanity.

However, the game was later shut down by the Kamen Riders and CR by defeating Gamedeus and Masamune Dan/Kamen Rider Cronus. As a final act of spite, Masamune Dan killed himself to prevent the victims of Kamen Rider Chronicle from being saved.
