The DLC includes three arenas, located in the three previously inaccessible elevators in the base game. They can be accessed after receiving the quest: Mysterious Letter. Each locations has its own challenges and quest.

After completing the three arenas the player will receive the final quest: Mysterious Invitation which tasks you with going to the Amusement Park and investigating a newly opened elevator. Once inside, a TV is available to interact with and doing so will allow the player to relive the memories of Plato 1728. At the end of this small story, a music video by rock band Amazarashi is played as the ending credits to this piece of DLC content. After the video, the player can exit the Park and will now have access to special challenge tiers in each of the arenas. Finally, a unique boss fight with CEO of Square Enix Yosuke Matsuda as well as Platinum Games head Kenichi Sato can be accessed by persistently asking the Resistance Secretary inside the Colosseum (Flooded City) arena for a fight with you-know-who.
