Diablo 4 Reveal Trailer

Diablo IV is an upcoming dungeon crawler hack-and-slash action role-playing game developed by Blizzard Entertainment, the fourth title in the Diablo series. The game was officially announced at BlizzCon 2019 on November 1, 2019.Release date has not been announced by Blizzard Entertainment, however some estimates predict the release some time during 2021.Three classes have been announced -- the Sorcerer, Barbarian and Druid. Two more classes are due to be revealed. The Druid class can shapeshift into wolves and bears. It can conjure animal allies and use natural phenomenon such as tornadoes. Mages can use schools of magic such as fire and frost, while Barbarians are designed around weaponry. Skill trees exist allowing for ability customization.
The game is unable to be played offline and will require an internet connection. In addition to this, the game possesses an MMO-like, shared world. Difficulties are removed due to this, though a Hardcore mode will remain. Similarly to Blizzard's World of WarCraft, dungeons are instanced to solo or party play. Players may choose the difficulty level of these dungeons. Player versus Player combat is possible in the game-world, and several zones are dedicated areas to this.
Player population in the world will shift depending on the area. Large settlements will display large populations, while to enforce a sense of desolation, more wild zones will change the amount of players shown to others. The world is open and mounts are available to travel. Mounts may also wear equipment which alters their functionality, and engage in combat. Terrain is three-dimensional and may be interacted with and destroyed, such as climbable rocks. The world will scale to player level but some areas are designed to be more challenging.
Areas of the game such as dungeons will be procedural generated like in previous Diablo games.
While Diablo III introduced different genders for classes, Diablo IV will allow for more extensive player appearance customization. Mount appearance can also be customized.
