Diablo IV Expansion, Vessel of Hatred, Set for Late 2024 Launch, Brings New Environment, Class, and Continues Series Storyline

First Diablo IV expansion introduces players to a lush jungle environment and a unique, never-before-seen class; while developer Blizzard tackles criticism around the game's endgame and itemization issues before late 2024 launch.

Blizzard announced the first expansion for Diablo IV, called Vessel of Hatred, due for a late 2024 release. It includes a campaign that continues from the main game's storyline, focusing on the prime evil character Mephisto and his schemes for the realm of Sanctuary.
The expansion introduces players to an entirely new jungle environment known as Nahantu, which is presumably located in the region of Kurast, revisited from Diablo II.
One of the most anticipated features of the expansion is the introduction of a unique class that the Diablo game series has never seen before, although the nature of the class remains to be revealed until next summer.
In response to players' criticisms of the base game, Blizzard is aiming to fix issues with 'dull itemization' and a lack of things to do in the endgame before Vessel of Hatred's launch.
Besides Vessel of Hatred, Diablo IV will also be updated during Season 3 with a new weekly challenge dungeon called The Gauntlet, and a mid-December seasonal event, Midwinter Blight, featuring a mysterious antagonist.
