DeNA has just announced that its upcoming Attack on Titan Tactics game for the Android and iOS platforms have opened for pre-registration. The beta-test for the game is scheduled to hit sometime early 2019.
As implied in the name, Attack on Titan Tactics takes a more strategic approach to the series, where players need to prowess the tactical know-how to defeat the Titans. One such tactic would be lure and trap said Titans in order to damage them.
Because it is already expected from such games, the original cast will be lending their voice talent and reprise their respective roles. At this juncture, we do know what the game really entails, but given the high profile nature of this game, expect more information to be made available sooner than later.
