Devil Survivor 2: Record Breaker

Devil Survivor 2: Record Breaker is a port of Devil Survivor 2. Characters in the Devil Survivor series were designed by Suzuhito Yasuda, illustrator of the Durarara!! light novels. For a limited time, Celty Sturluson, Shizuo Heiwajima, and Izaya Orihara were available for download in the game.

Gameplay
Celty is one of the first characters to appear during the collaboration. After players bring her various fairy demons, they can receive the Headless Rider's PDA COMP. Her outfit can also be acquired with the helmet unequipped. Female players wearing the outfit appear headless.

Upon completing various quests for Shizuo, players can receive Ikebukuro's Strongest Man Sign, a melee weapon shaped like an uprooted street sign. Shizuo's outfit can also be acquired by the player and grants them a unique skill.

Izaya appears in the second half of the collaboration event requesting a "knife of this world" as well as a "snack with personality." Upon being given these things, he provides players with the Shady Informant's Knife.
