Diablo: Immortal will arrive on PC, iOS and Android in most parts of the world on June 2nd. Folks in some Asia-Pacific regions will need to wait a few extra weeks. It's a free-to-play title with some optional in-game purchases. The PC version will initially be in open beta, but will have all content and features. All progress and purchases will carry over too.
It will feature cross-play and cross-save support for all platforms, so you should be able to switch between PC and your mobile device with ease. The MMORPG allows players to take on challenges with eight-person parties and it has a faction-based PvP system.
Unusually for a Diablo game (which are usually point-and-click titles), Diablo: Immortal will have the option of directional keyboard controls. The mobile control system allows for simultaneous movement and attacks, which Blizzard says wouldn't be possible solely through mouse control alone. There's also controller support on PC.
