The Diablo series is one of the most influential action role-playing game (ARPG) franchises ever created. Developed originally by Blizzard North and later by Blizzard Entertainment, the series has captivated millions of players worldwide with its dark fantasy setting, addictive loot-driven gameplay, and intense hack-and-slash combat.
The franchise debuted in 1997 with the original Diablo, followed by Diablo II (2000) and its highly praised Lord of Destruction expansion. Later came Diablo III (2012) with Reaper of Souls and Rise of the Necromancer, and most recently Diablo IV (2023) alongside its first expansion Vessel of Hatred (2024). Additional titles include Diablo Immortal (2022) for mobile devices and the remaster Diablo II: Resurrected (2021).
Set in the dark world of Sanctuary, the series follows humanity’s struggle against the forces of the Burning Hells, the High Heavens, and the Prime Evil himself — Diablo, the Lord of Terror. Over its history, the series has sold nearly 100 million copies and has become synonymous with the ARPG genre.

What Is Diablo About?
At its core, Diablo is a dark fantasy saga of eternal conflict between angels and demons, with humanity caught in between. The central narrative revolves around Sanctuary, a world created by rebel angels and demons seeking refuge from the Eternal Conflict. Humanity, descended from their offspring — the Nephalem — possesses untapped power that both sides seek to influence.
Diablo, the series’ titular antagonist, is one of the seven Great Evils and later becomes the Prime Evil by absorbing the powers of his siblings Baal and Mephisto. The games follow various heroes (player characters) who rise to face the demonic threat, explore procedurally generated dungeons, defeat powerful bosses, and collect ever-improving loot.
