Previously, DeNA teased the coming of a new Attack on Titan mobile game via the release of a teaser website. DeNA has now gone further to release the official Twitter and a TVCM for the new game titled Attack on Titan Tactics.
Asides from the title. nothing much has been confirmed about the game, but from the gameplay footage seen in the newly released TVCM, the game appears to be some sort of tower-defense game where players will have to summon different characters to defend against waves of titans.
Attack on Titan Tactics is expected for mobile this winter.
