This year marks the 30th anniversary of the Diablo series, and one of the most generous celebrations is now available to Diablo 4 players. Xbox Game Pass subscribers can claim a total of 57 cosmetic items for free throughout September.

Where does the content come from

This free bundle arrives with Diablo 4's new season, Season of Hell's Legacy (Season 15), which began on September 15. The season focuses on the franchise's history, brings back Deckard Cain, highlights the Prime Evils including Diablo, introduces Nightmare Rifts, and offers special anniversary rewards for players returning to Sanctuary. The Xbox Game Pass bonus is one of the most tangible perks for players during this big celebration.

This isn't your usual Game Pass bonus

Here's an important detail: this doesn't mean the game itself is coming to Game Pass. Instead, it's a limited-time cosmetic pack for existing players. The bundle can be accessed via the "Benefits" section of the Xbox Game Pass app and includes six armor sets, themed weapons, mount cosmetics, a Town Portal skin, an emblem, and a gravestone—57 items in total, available for both Xbox and PC versions.

How to claim

1. Make sure you have an active Xbox Game Pass subscription.
2. Link your Microsoft account to your Battle.net account using Blizzard's account linking process.
3. Once linked, log in to Diablo IV.
4. All eligible cosmetics you don't already own will be automatically added to your account.

The rewards are applied directly to your linked account, not through a manual code. If the connection is correct but you don't see the rewards right away, double-check your subscription status and restart the game.

What if you already own some items

According to Blizzard, if you already own an item from the collection, you'll only receive the ones you don't have. There are no alternative rewards or in-game currency for duplicates. So, the "57 items" number may feel different for each account; long-time players who have collected most cosmetics will see fewer new items than those who haven't purchased any before.

This isn't the only opportunity

During the same season, there's also a Twitch Drops event running from September 16 to 30. By watching two hours of Diablo IV streams, players can earn the Deforestation two-handed axe cosmetic. These two promotions are separate; owning the Game Pass items doesn't remove the Twitch viewing requirement, and earning the Twitch reward doesn't unlock the Game Pass pack.

What's next

This generous celebration arrives as Blizzard officially announces Diablo 5, set for release in Spring 2029. Meanwhile, Diablo 4 continues to be the focus of the franchise, and the Season of Hell's Legacy plus the new Game Pass bundle give players another great reason to return to Sanctuary.
