Harry Potter: Hogwarts Mystery
Back in January, Portkey Games, the arm of Warner Brothers dedicated to publishing Harry Potter titles, revealed that indie developer Jam City was working on a mobile RPG set in the universe. This game is notable because, despite the confusing title, Harry Potter doesn't show up anywhere in it. This is a prequel game set years before the events of the book, where you get to run around as a student of one of the houses.
Today Portkey and Jam City revealed a new teaser that shows off more gameplay features, including potion making and wizard duels. You can watch the whole thing here:
The game is due out in Spring 2018.
