ZZZ Version 3.1 Brings Six-Agent Selector and Star Rail Crossover Teaser
HoYoverse's free-to-play action RPG Zenless Zone Zero is marking its second anniversary with Version 3.1, arriving July 29, and the headline reward is a free S-Rank agent selector - paired with a matching W-Engine - letting players choose from Jane, Soldier 0, Anby, Hugo, Trigger, or Lucia.
That's a meaningful package for any active roster. HoYoverse has leaned on targeted free premium units as milestone rewards across its portfolio, and ZZZ continues that pattern here with a selector wide enough to cover several practical team needs rather than funneling players toward a single choice.
Version 3.1 Content Breakdown
- Free selector: One S-Rank agent and W-Engine from a pool of six - Jane, Soldier 0, Anby, Hugo, Trigger, or Lucia
- New agent - Remielle Dan, Lumiflux: Introduces the Lumiflux attribute type, which lets Remielle change her damage attribute based on the attribute of the next Agent in the squad, meaning her attributes will change based on the teams she’s in
- New agent - Sigrid: Airspace Patrol's Deputy Director arrives as an Ice Attack agent in the second half of the update
- Signal Search banners: Remielle runs throughout the full version; the first half reruns Aria, while the second half brings back the Exclusive Rescreening channel with simultaneous reruns of Dialyn, Yuzuha, and Harumasa - players can choose which will be their rate-up Agent
- New permanent mode - Enigma of the Labyrinth: Operation Bagel: A seasonal dungeon mode tied to rescuing Eous, with weekly progress shared with Hollow Zero
- Anniversary currency: 1,600 Polychrome and 10 Encrypted Master Tapes distributed across update events
- Free outfit: Lucy's swimsuit outfit awarded for completing the Fantasy Resort event return
- Redemption code: ZZZY2ANNIV, valid through July 19
The update also advances a significant story beat - all major factions converging in one place - alongside the return of a character whose earlier appearance ended in another agent's death. ZZZ has maintained a steady cadence of story-driven content drops since launch, and 3.1 appears to be a genuine narrative milestone rather than a filler version.
The bigger piece of news dropped at the end of the Version 3.1 stream: a Zenless Zone Zero and Honkai: Star Rail crossover is confirmed for this winter, which retroactively explains Pom Pom's recent appearance in the in-game video store. No additional details on scope or timing beyond the season window have been confirmed.
