The smartphone game Chain Chronicle 3 is teasing an upcoming collaboration with Attack on Titan on a recently opened teaser site. The game, which previously crossed over with Persona 5 and Madoka Magica , is keeping its secrets in the proverbial basement for now. Players can pre-register to get notifications as soon as the collaboration starts.

Attack on Titan Season 2 premieres on April 1 and will broadcast on 21 Japanese television stations. The hit manga series and its successful first season have managed to stay in the limelight for the four years since the first season debuted. The franchise is currently enjoying a run at Universal Studios Japan, an upcoming fashion show, endless merchandise, and video game appearances.

The Chain Chronicle mobile game inspired a television anime and anime film series project this year.
