Diablo IV

• 1. Introduction

  ›

  Diablo IV crossed one billion dollars in total revenue by September 2024, making it one of the fastest commercial rises in the history of its genre. But the road to that milestone was anything but smooth. The game's original concept, code-named Hades, was cancelled outright when its lead designer left Blizzard in July 2016. Its eventual game director was pushed out before launch. A lawsuit against the parent company reshuffled the entire development team. And yet, on the 5th of June 2023, Diablo IV launched to near-universal acclaim, broke the sales record for the fastest-selling game in Blizzard Entertainment's history, and generated $666 million in its first five days. What does it take to build a game that survives that much internal chaos? And what choices did the team make that turned a cancelled prototype into a cultural moment?

• 2. A Series Reborn Dark

  ›

  Game designer Jesse McCree stated that heavy metal was the direct aesthetic inspiration for Diablo IV's look and feel. Art director John Mueller drew on the old masters of painting as well as more modern artists, including Frank Frazetta and Gerald Brom, to set the visual tone. The development team wanted something between the darkness of Diablo II and the hand-painted quality of Diablo III, filtered through medieval fine art. Ex-game director Luis Barriga described the atmosphere with a specific goal: to make users feel like they are inside a medieval city. That meant all assets were rendered as standard 3D game objects for the first time in the series, and terrain was given genuine elevation. In-game cinematics and environmental interaction became possible as a result. Creative director Sebastian Stepien pushed the narrative away from high-fantasy politics toward stories of simple folk living in the world of Sanctuary. The effect was a game that felt grounded in ways the series had not attempted before.

• 3. Eight Classes, Endless Builds

  ›

  The Barbarian, Sorcerer, and Druid were the first three classes revealed at BlizzCon 2019. The Rogue followed at BlizzCon 2021, and the Necromancer was announced in 2022. Each class is voiced by two actors: for example, the Barbarian is voiced by Ray Chase and Laila Berzins, while the Druid is voiced by Andrew Morgado and Courtenay Taylor. Beyond voice, each class carries a mechanical identity. The Druid can shapeshift between human, werewolf, and werebear forms. The Rogue alternates between bladed melee and ranged combat with a bow. The Rogue's design specifically aimed to capture the high-dexterity feel of the Assassin from the second game and the Demon Hunter from the third. Three new attributes unique to Diablo IV shape how builds work: Angelic Power, which alters how long beneficial effects last; Demonic Power, which alters how long negative effects last; and Ancestral Power, which increases the chance of effects spreading to other targets. Lead game designer Joe Shely and senior producer Tiffany Wat confirmed that trading and crafting are present but limited to resources outside the most powerful items, preserving the significance of top-tier loot.

• 4. An Open World Under Pressure

  ›

  For the first time in the series, Diablo IV places players inside a fully open world with no loading screens between its seven regions. Those regions range from the frozen caves of the Fractured Peaks to the swamp-bound witch country of Hawezar to the cannibal-haunted Dry Steppes, where the source describes the land as so harsh that inhabitants have turned to cannibalism. Enemies scale to the player or the party leader, and the story can be pursued in any order. Player population within the world shifts dynamically: large settlements show many players, while wilder zones deliberately reduce the number of players visible to enforce a sense of isolation. Procedurally generated dungeons remain separately instanced from the open world, so non-party players do not appear inside them. The dungeons themselves use random layouts of both interior and exterior environments, continuing the series tradition of replayable underground exploration. Player versus player combat exists in select overworld areas, alongside boss events that any passing player can choose to join.

• 5. The Story of Lilith

  ›

  Caroline Faber voices Lilith, the daughter of the Prime Evil Mephisto and the game's central antagonist, returning after being banished to the void thousands of years before the story begins. She and the angel Inarius, voiced by Gabe Kunda, created the realm of Sanctuary as a refuge from the war between the High Heavens and the Burning Hells. Their union produced the Nephalem, a race that is neither angel nor demon but a distinct combination of both. When the inhabitants of Sanctuary feared the Nephalem's power would draw attention to their refuge, Lilith killed those who threatened her children; Inarius responded by banishing her. The player character, called the Wanderer, becomes tied to Lilith through a forced ritual early in the game. Ralph Ineson voices Lorath Nahr, one of the last surviving Horadrim, who explains the prophecy of Lilith's return. The story moves through encounters with figures voiced by Judy Alice Lee as Neyrelle, James Goode as Donan, and Anthony Howell as Elias, the apprentice who originally summoned Lilith. Steve Blum voices Mephisto, who appears in disguised form throughout the story as a bloodied wolf. At the game's climax, Neyrelle chooses to trap Mephisto in a Soulstone rather than destroy Lilith, believing him the greater long-term threat. Lilith's dying words warn that without her, there can be no victory over the Prime Evils.

• 6. Turbulent Development

  ›

  Josh Mosqueira first conceptualized the game under the code name Hades after the 2014 release of Diablo III: Reaper of Souls. His vision involved over-the-shoulder combat modeled on the Batman: Arkham series, permadeath, and multiplayer. When Mosqueira left Blizzard in July 2016, that version was cancelled and development restarted from scratch. The game was publicly announced on the 1st of November 2019 at BlizzCon. Then, as of July 2021, both game director Luis Barriga and game designer Jesse McCree were no longer employed at Blizzard, following the California Department of Fair Employment and Housing lawsuit against Activision Blizzard. High employee turnover led Blizzard to announce that the game would not ship in 2022. Blizzard president Mike Ybarra later confirmed that Diablo IV took more than six years to develop from the point of its restart. Open beta weekends ran in March and May 2023, and users reported that the game caused some Nvidia RTX 3080 Ti graphics cards to overheat and stop functioning; both Blizzard and Nvidia stated in March 2023 that they were working to resolve the issue. The game released on the 5th of June 2023, with early access beginning on the 1st of June.

• 7. Record Sales and Critical Praise

  ›

  On the 6th of June 2023, Blizzard Entertainment announced that Diablo IV had become the fastest-selling game in the company's history. The title generated $666 million in revenue in its first five days and reached 12 million players by August 2023. In Japan during its first week, the PlayStation 5 version sold 24,375 physical units, ranking it second on the retail chart; the PlayStation 4 version sold 8,524 units and placed fifth. Across all platforms in Japan, the game sold 41,839 retail units in that first week. Diablo IV was the sixth best-selling video game in the United States for the full year of 2023. On the critical side, Metacritic classified the Windows and PlayStation 5 versions as receiving generally favorable reviews, while the Xbox Series X version reached universal acclaim. Windows Central called it Blizzard's magnum opus and described it as the most important Blizzard game since World of Warcraft. Travis Northup of IGN called it a spectacular sequel. Alessandro Barbosa of GameSpot wrote that the story was moving and engrossing, particularly praising the handling of Lilith. VG247 described the soundtrack as exceptional, equal parts haunting and daunting. On the 15th of January 2024, Microsoft Gaming announced that Diablo IV would be added to Game Pass on the 28th of March 2024.

• 8. Expansions and Awards

  ›

  The first expansion, Vessel of Hatred, was announced at BlizzCon 2023 and released on the 8th of October 2024. It introduced the Spiritborn class, voiced by Stephen Fu and Dawn Bennett, which calls on four spirit guardians: Centipede, Eagle, Gorilla, and Jaguar. The second expansion, Lord of Hatred, was announced at The Game Awards 2025 and released on the 28th of April 2026. It added the Skovos Isles region and introduced two new classes: the Paladin, voiced by Keston John and Sasha Sloan, which offers four oath-based play styles; and the Warlock, voiced by Din Mayfield and Arianna Ratner, a brand-new class wielding hellfire, summoned demons, and eldritch magic. On the awards circuit, Diablo IV received nominations at the Golden Joystick Awards, The Game Awards 2023, the 27th Annual D.I.C.E. Awards, the 24th Game Developers Choice Awards, and the 20th British Academy Games Awards. The Game Audio Network Guild nominated the game across ten audio categories alone, including Dialogue of the Year and Best Cinematic and Cut Scene Audio. The Wanderer who defeated Lilith faces the prospect that Neyrelle, now travelling alone with Mephisto contained in a Soulstone, will need to find a way to destroy the Prime Evils for good.
