Diablo IV is in a free play window on Steam that runs until September 22, paired with the Season of Hell's Legacy launch and a 75 percent discount on the Steam version. The Nintendo Switch 2 release of Diablo IV: Age of Hatred Collection is dated for September 16 in Japan, following a BlizzCon demo.
Diablo IV's fall 2026 push moves on two fronts: a renewed free-entry offer on Steam and the Nintendo Switch 2 version of the Age of Hatred Collection. Blizzard opened a free play period on September 16 running until September 22 at 2:00 AM, with all classes playable up to level 30. The Steam version is 75 percent off at 1,675 yen until September 25, which the reporting calls a new lowest price. The new season, Season of Hell's Legacy, began the same day, so the free window and the season reset arrive together rather than in sequence.
The Switch 2 release was set in motion at BlizzCon 2026 in Anaheim. Blizzard announced the Age of Hatred Collection with a September 15, 2026 release and a Japanese release on September 16. The package includes the base game, the Vessel of Hatred and Lord of Hatred expansions, supports Japanese, and supports crossplay and cross-progression. It requires an internet connection and a Battle.net account, and ships in code-in-box format. A hands-on demo at the show ran without lag or stuttering with fast loads; players ran a dungeon quest called A Journey Through the Past against Belial, then Mephisto and Baal.
Outside the release track, Blizzard tied Diablo IV to a partnership with CD PROJEKT RED announced on August 26. A Geralt-themed skin is obtainable by pre-purchasing or purchasing The Witcher 3: Wild Hunt expansion pack 'Memories of Reminiscence' on Battle.net, with the skin's appearance unrevealed. Diablo IV also appears in the BlizzCon Digital Bundle and BlizzCon Ultimate Collection sold on the Battle.net shop from 3,350 yen, alongside items for World of Warcraft, Overwatch, Diablo Immortal, and Hearthstone.
