Diablo III is a dungeon crawler action role-playing video game developed and published by Blizzard Entertainment. It is the third installment in the Diablo franchise and was released on May 15, 2012 for Microsoft Windows and macOS. A console version was released for the PlayStation 3 and Xbox 360 on September 3, 2013. Versions for PlayStation 4 and Xbox One were released on August 19, 2014. In the game, players choose one of seven character classes – Barbarian, Crusader, Demon Hunter, Monk, Necromancer, Witch Doctor or Wizard (with the Crusader being unavailable unless the player has purchased the expansion pack, Diablo III: Reaper of Souls and the Necromancer added later as separate online purchase) – and are tasked with defeating the Lord of Terror, Diablo. Diablo III set a new record for fastest-selling PC game selling over 3.5 million copies in the first 24 hours of its release, and was the best selling PC game of 2012, selling over 12 million copies during the year. It has sold, along with Reaper of Souls, 30 million copies across all platforms. Diablo III received critical acclaim from critics, although its digital rights management that requires an internet connection at all times was criticized.

For consoles the expansion pack content was released as part of the Diablo III: Ultimate Evil Edition version. It was released for the PlayStation 4, Xbox One, PlayStation 3, and Xbox 360 on August 19, 2014. Diablo III: Ultimate Evil Edition includes the original console version of Diablo III and Diablo III: Reaper of Souls expansion pack. The second expansion Diablo III: Rise of the Necromancer was released for the Windows, macOS, and latest-generation console editions of the game on June 27, 2017.
