The March issue of Kodansha 's Bessatsu Shōnen Magazine announced on Thursday that the Shingeki no Kyojin : Chain Puzzle Fever app will open pre-registrations in the latter half of February. The game is slated for release this winter, though no platform has been announced for the game.

The magazine is also revealing that the Castle & Dragon smartphone game app will launch a collaboration event with Attack on Titan that will run from February 16 to March 2. The collaboration will feature Eren and Mikasa outfits, a Survey Corps egg, and the Colossal Titan as an attacker that the players must defeat.
