Zenless Zone Zero Version 3.1 Release Date and Key Content

Zenless Zone Zero Version 3.1 officially went live on July 29, 2026. The update is called “The Long Goodbye” and serves as the main content release connected to the game’s second-anniversary celebrations.The date requires some clarification. Zenless Zone Zero originally launched on July 4, 2024, meaning its exact second anniversary fell on July 4, 2026. However, the larger anniversary update, new playable characters and major rewards arrived with Version 3.1 on July 29.The release is more than a routine character-banner update. It introduces new story developments, new Agents, anniversary rewards and additional platform support. Remielle is the headline character, while Sigrid, Deputy Director of the Airspace Patrol, also appears as part of the update’s new content.

HoYoverse describes Version 3.1 as the update celebrating Zenless Zone Zero’s second anniversary, while Xbox Wire confirms that the July 29 content includes Remielle, Sigrid and an anniversary S-Rank Agent selection opportunity.

Remielle Arrives as the Headline Version 3.1 Agent

Remielle is the central new character in Version 3.1. Official promotional material identifies her as a first-generation Void Hunter who had been sleeping for a century before returning during the events of the new update.The Void Hunter title is especially important in Zenless Zone Zero’s world. It connects Remielle to the legendary figures who played defining roles in the history of New Eridu and the conflict surrounding the Hollows. Her arrival therefore carries greater narrative weight than the introduction of a standard new faction member.Official HoYoverse material also presents Remielle as the first playable Agent associated with the new Lumiflux Attribute. Her combat identity is built around unusual Attribute interactions and flexible team composition, making her one of the most distinctive Agents introduced in the game so far.

Remielle is an S-Rank Anomaly Agent. Rather than focusing only on direct burst damage, her role is connected to Attribute Anomaly mechanics and the application of combat effects through her unique Attribute. Players interested in building new Anomaly teams will therefore have a major reason to explore Version 3.1.Xbox’s official announcement describes her as a first-generation Void Hunter who “slumbered for a century,” confirming that her return is directly tied to the new story. The same announcement introduces Sigrid alongside her and teases a new relationship shaped by blades, Ether and developing trust.

What Makes Remielle Important?

Remielle is significant for several reasons:

1. She is a new S-Rank Agent.

2. She follows the Anomaly combat specialty.

3. She is identified as a first-generation Void Hunter.

4. She introduces the new Lumiflux Attribute.

5. Her return is connected directly to the Version 3.1 storyline.

6. She is presented as one of the main characters of the second-anniversary update.

Players should not confuse Remielle’s banner with the free anniversary S-Rank selection. HoYoverse promotes Remielle as a new Version 3.1 Agent, while the free anniversary reward is a separate system that allows players to choose from an eligible selection of S-Rank Agents. The official announcements do not state that Remielle herself is given away for free.

Zenless Zone Zero Second-Anniversary Rewards

The second-anniversary celebration is one of the most valuable parts of Version 3.1. The largest confirmed reward is the ability to select an eligible S-Rank Agent.This is different from receiving a random S-Rank character. The official wording indicates that players can make a selection through the anniversary reward system, giving them more control over which Agent they obtain.The celebration also includes a corresponding exclusive W-Engine. A W-Engine is Zenless Zone Zero’s main equippable weapon category, and exclusive S-Rank W-Engines are generally designed to work particularly well with their associated Agents.As a result, the anniversary reward provides more than a character alone. It gives players the opportunity to claim an eligible S-Rank Agent together with that Agent’s matching equipment, creating a more complete starting build.

Xbox Wire explicitly tells players to “Select an S-Rank Agent for the 2nd Anniversary,” while HoYoverse’s anniversary announcement confirms the broader free limited S-Rank Agent and corresponding W-Engine promotion.Because event access rules may depend on account progress, login timing or in-game unlock conditions, players should check the Version 3.1 event interface before making a final selection. The official event page and in-game notices should be treated as the final authority for eligibility and deadlines.

Zenless Zone Zero Expands Across the Xbox Ecosystem

Version 3.1 also marks a major platform milestone for Zenless Zone Zero. The game expanded its presence across the Xbox ecosystem alongside the July 29 update.Xbox’s official pages list Zenless Zone Zero among recently added Xbox titles, while Xbox Wire confirms July 29 availability for its PC-related Xbox offering and promotes the Version 3.1 anniversary benefits to Xbox Game Pass members.This platform expansion gives more players access to New Eridu while strengthening Zenless Zone Zero’s cross-platform reach. Before this release, the game was already available through PlayStation 5, Windows PC, iOS and Android. Its Xbox arrival places the game in front of another large console and PC audience.Players should distinguish between the free-to-play game itself and Xbox Game Pass benefits. Zenless Zone Zero remains a free-to-play title. Xbox Wire separately lists Version 3.1-related in-game benefits for eligible Game Pass tiers, including the anniversary content available from July 29.The Xbox launch is particularly important because it arrives simultaneously with one of the game’s strongest onboarding periods. New players can enter during a major update, meet Remielle through the new story and take advantage of the anniversary S-Rank selection rather than starting during a quieter patch.

What Should Players Do First in Version 3.1?

After installing the update, players should begin by reviewing the anniversary event menu and checking the exact conditions for the free S-Rank Agent and W-Engine.

Before confirming a selection, it is worth comparing:

1. The Agent’s combat specialty

2. The Attribute used by the Agent

3. Existing team members

4. Available Drive Discs

5. Whether the matching W-Engine improves an existing team

6. Whether the account needs a damage dealer, support unit or Anomaly specialist

Players interested in Remielle should also review her trial stage and official ability descriptions before using Encrypted Master Tapes. Her Lumiflux mechanics and Anomaly-focused role may require a different team-building approach from more conventional Attack Agents.Xbox players should make sure that they sign into the correct account before starting. Using the correct HoYoverse account is important for accessing existing progress where supported and avoiding the creation of an unintended new game profile.
