In collaboration with Rooster Teeth, NHN Entertainment Corp announced that it will be bringing a strategy title in the form of RWBY: Amity Arena to the mobile platforms sometime in 2018.
Game details are so far very sparse, although we know that it involves creating a team of Huntsmen and Huntresses to participate in the Vytal Festival, where teams will duel in a variety of settings.
A large cast of RWBY characters will be featured here obviously, and you will be able a team of your favourites, although you will have to take into consideration the strengths and weaknesses of each person for the sake of optimisation.
That is pretty much all we know about the game for the time being, but you can expect more details down the line as we get them.
