Zenless Zone Zero’s 3.1 update went live on Wednesday, July 29, 2026, after maintenance on Tuesday, July 28. This patch is a major one for New Eridu, especially because it marks the game’s second anniversary. Players who had reached level four or higher by the end of maintenance received at least 300 Polychrome as downtime compensation, which is a handy little boost before the new banners arrive.

Before the patch, the version 3.1 special program aired on Friday, July 17 at 19:30 UTC+8. For those keeping track by region, the start times were 4:30 PDT, 6:30 CST, 7:30 EDT, 12:30 BST, 13:30 CEST, and 21:30 AEST.

Version 3.1 features a packed selection of limited characters. Hoyoverse confirmed that Remielle, Aria, Sigrid, Dialyn, Ukinami Yuzuha, and Harumasa are the featured agents this update. Alongside these character banners, each featured unit has a limited W-Engine banner for their signature gear. Players who want to plan their Polychrome spending should keep an eye on rotating banner phases, because the order will change over the course of the patch.

Featured Agent Banner Type
Remielle Limited character and W-Engine
Aria Limited character and W-Engine
Sigrid Limited character and W-Engine
Dialyn Limited character and W-Engine
Ukinami Yuzuha Limited character and W-Engine
Harumasa Limited character and W-Engine

Story and Events

This update introduces Season 3 Chapter 2: The Long Goodbye. The story chapter explores Remielle’s role and sheds more light on the mysterious Enchainer. In typical ZZZ fashion, the new chapter should offer a mix of story missions, combat encounters, and universe-building that sets up later content.

Because version 3.1 is an anniversary patch, the event calendar is especially stacked. The flagship event, Summer Waves Roll In, has two minigames where players go beachcombing and then sell their haul in a shop. That relaxed summer tone fits the anniversary celebration, but there are also plenty of combat and challenge events for those who want something more intense.

New Optimizations

Hoyoverse is also using 3.1 to deliver a large batch of quality-of-life and systems upgrades. One of the more playful additions is Eous’ brand-new robot mount, which can roll, charge up, and slam forward to solve puzzles. There’s also a new permanent mode called Enigma of the Labyrinth: Operation Bagel, giving players another long-term activity. Adversity Mode expands Deadly Assault for those who want a harder challenge.

  • πŸ‘— Two new outfits for Remielle, plus one each for Vivian, Sigrid, and Lucy

  • ✨ Agent enhancements for Jane, Nekomata, and Rina, providing buffs to their kits

In short, version 3.1 has a little something for everyone. Story fans get new narrative content, collectors get new outfits and freebies, and min-maxers get new modes and agent enhancements.

Overall, the second anniversary update is one of the more generous patches Zenless Zone Zero has dropped in 2026. The combination of a strong story chapter, six featured banners, a huge anniversary event schedule, and meaningful systems improvements makes it a great time to jump back into New Eridu. Players should keep checking the in-game announcements, because banner phases and event details will keep shifting as the patch progresses.
