Diablo Immortal, the first-ever mobile entry of the Blizzard franchise announced with quite the uproar back at BlizzCon 2018, just passed a new development milestone as it is now being tested internally across the entire company. That means the public release isn't due soon as the developers will first have to go through the feedback of their own colleagues and make appropriate changes, but it is getting there, according to Lead Designer Wyatt Cheng.

The Diablo Immortal team is eager to see how our Blizzard colleagues around the world experience our game. From the very first login to choosing a Legendary item to perfectly complement your build, we’ll be soliciting feedback to guide our decisions as we iterate on the game before it goes beyond Blizzard’s walls. In our quest to reimagine what is possible on mobile, we want to make sure the game delivers authentic Diablo combat with traditional Blizzard polish in a way that is natively intuitive on the platform.
