Activision Blizzard Inc. unveiled much-anticipated details about “Diablo IV” Friday when it kicks off BlizzCon 2019, its two-day annual video-game showcase in Anaheim, California.

"After the destruction of the Black Soulstone, the defeat of the Prime Evil, and the fall of Malthael, Angel of Death, countless lives have been lost and the denizens of Sanctuary find themselves struggling through the darkest of ages. Years have passed and, as some semblance of regular life starts rebuilding, a threat as old as the land itself begins to stir."

Hellish new features, brutal challenges, and an indisputable return to darkness lie at the core of the new game.

Diablo IV takes place many years after the events of Diablo III, after millions have been slaughtered by the actions of the High Heavens and Burning Hells alike. In the power vacuum, a legendary name resurfaces—Lilith, daughter of Mephisto, the whispered progenitor of humanity. Her grip on Sanctuary cuts deep into the hearts of men and women alike, cultivating the worst in its denizens and leaving the world a dark, hopeless place.

With Diablo IV, Acrivision is opening the campaign approach to broaden Sanctuary. With a fully open world, players will be able to adventure across five regions in any order, all connected for uninterrupted journeys.

"Mount up and roam from zone to zone completing public events with others or explore populated town social hubs to party up and trade. Challenge a world boss or even other players for treasure and glory! The world, along with its deadly inhabitants, awaits."

While it’s dangerous to go alone, you might prefer to solo your way through Sanctuary. Anyone can explore the campaign at their own pace, plumb randomized dungeons for rare loot, and find any item without joining a group. Keyed dungeons will offer a new endgame experience available to individual players as well as groups of up to four.

Players will be able to choose between five different, unique classes on launch. Let’s start with a few fan favorites, three of which we’re revealing today at BlizzCon:

• The Barbarian: Crush enemies and wade through combat with reckless abandon.
• The Sorceress: Freeze, scorch, or shock your foes with immeasurable arcane power.
• The Druid: Shift between primal forms while commanding the fury of nature itself.

The game will probably be released in 2021. Blizzard Entertainment will offer odr information about the new game tomorrow.
