In the electric arteries of New Eridu, where Hollow ether crackles like a nervous pulse, a Proxy’s calendar is not just a list of dates but a living map of fleeting chances. A missed event is a dropped stitch in a very fragile fabric, and by the time the thread is found, the reward has already scattered like ash from a fading bonfire. For the Proxy who keeps one eye on the shifting tide of commissions and the other on the next free polychrome, this guide serves as a lantern in the Hollow.
The Version 3.1 calendar in 2026 is dense with anniversaries, summer festivals, and permanent systems that reward patience as much as skill. Here is everything a Proxy should keep on the radar.
Current ZZZ Events in 2026
Anniversary Login Celebration — July 29 to September 8
The second anniversary of Zenless Zone Zero arrives with a generous login streak. Any Proxy who simply checks in can claim 1.6k polychrome, an anniversary avatar, and an anniversary title. The real prize, however, is the choice of one S-rank agent from Jane, Lucia, Hugo, or Trigger, along with that agent’s signature S-rank W-Engine. For newer accounts, this is like being handed a master key before the first locked door even appears.
Beachcombing and the Bonfire Summer — July 29 to September 7
After pulling Fantasy Resort back from the brink last year, this event sends Proxies to the beach for a low-stakes but rewarding rhythm. They gather sea creatures through a beachcombing minigame, then return to the souvenir shop to sell the wares and fund the upcoming bonfire party. The loop is simple, but the summer economy hums like a beehive stitched from salt and sand. Rewards include polychromes, an exclusive namecard, a hamster cage pass, and Lucy’s new summer outfit.
Grand Reveal of the Year — July 29 to September 9
Fairy and Eous kick off a special anniversary livestream to look back over the past year. Completing event missions grants an event-exclusive namecard, polychromes, and more. It is a quieter event, but the narrative weight is real for those who enjoy the story woven through New Eridu’s neon streets.
Omond Research Station — Start of Version 3.1, Permanent
This permanent addition sends Proxies into the Omond Research Station left behind by Joyous. The goal is to get the equipment running again and locate Eous. Delving into the Hollow’s depths is a careful balance of supply gathering, enemy clearing, and retreating within the time limit. Supplies then feed into equipment and research station repairs, which expand the search range and stack rewards over time. It is not a sprint; it is closer to tending a slow-burning forge.
Upcoming ZZZ Events in 2026
- August 7 to 24 — Lens and Ember Photo Event
Proxies must snap photos both in and out of combat to meet specific criteria. The shutter captures two flames: the ember of daily life and the blaze of battle.
- August 24 to September 7 — Remielle’s Fugitive Model
A first-generation Void-Hunter cannot become a wanted fugitive without becoming a photography model. Even with wanted posters plastered across Booastrum, Remielle strikes a pose. Capturing her in various locations earns polychromes, boopons, and other goodies.
- August 28 to September 14 — The Wish Post Office
Starlight adorns the letters, and miracles entwine with wishes. Proxies help the client Bangboo deliver Wish Letters to claim polychrome rewards and uncover the secrets behind the Wish Post Office.
- August 12 to 17 — Area Patrol Triple Rewards
Claim triple rewards from Area Patrol challenges a set number of times per day.
- September 2 to 7 — Combat Simulation Triple Rewards
Claim triple rewards from Combat Simulation challenges a set number of times per day.
Permanent ZZZ Events in 2026
Suibian Temple
A decade of gloom is finally clearing. Proxies take charge of running Suibian Temple as it was eleven years ago. This management minigame involves sending Bangboo on expeditions, crafting goods, selling them for Cloud Crests, and upgrading the temple. Commissions also require rescuing trapped citizens in the Hollows while watching for miasma. The spoils include polychromes, materials, and cute cosmetics.
Endless Tower
Until the last drop of blood is shed, until the last blade is broken. The Endless Tower returns with phases of ten floors. Reaching level 50 and earning all badges unlocks continued challenges in ten-floor phases. Before each entry, Proxies choose one of three modifiers, and clearing each floor grants the next battle’s reward effect. Most modifiers carry both positive and negative effects. New badges, titles, avatars, and achievements await.
Hollow Zero: Lost Void
The threat is not yet gone. The new Perpetrator Battle gameplay debuts in Hollow Zero: Lost Void. Proxies use designated agents, supplied gear, and resonia to defeat strong enemies and earn rewards.
Deadly Assault
The Defense Force-exclusive enemy combat training system returns in seasons. Each season features three powerful enemies with special high-ether activity effects. Different agents and Bangboo must be used for each enemy, so team building is part of the test. Reaching score thresholds earns film, denny, and more. Seasons rotate every two weeks.
Hollow Zero Investigation Commissions
Ray, the White Star Institute research representative, has disappeared. Proxies head to Lost Void, use ether resonance abilities, and save the day in exchange for heaps of goodies.
Withering Garden Blitz Mode
Version 1.2’s blitz mode remains a fast way to earn weekly investigation points without exploring the TV board. After each fight, a resonium surprise box appears. Difficulty modifiers now apply to exploration mode as well.
Road to Proxy Greatness
Reach Inter-Knot level eight and unlock the event feature in the Main Story Prologue - Intermission to access this reward track.
| Inter-Knot Level | Reward |
|---|---|
| 5 | Ten master tapes and ten boopons |

Investigator Training Course and Tactical Course

Rain’s Combat Commissions and Tower
Rain has a batch of difficult commissions. The figure in the Hollow seems familiar. The permanent combat tower also lets Proxies climb floors for rewards, with a badge that grows shinier with each climb.

For a Proxy in 2026, the event calendar is not a simple list; it is a constellation of short-lived stars. Miss one, and the light has already curved away. But with a steady hand on the compass and a calendar pinned to the wall, the spoils of New Eridu do not have to slip through the cracks.
This discussion is informed by reporting from VentureBeat GamesBeat, whose coverage of live-service strategy helps frame why Zenless Zone Zero’s 2026 event cadence leans so heavily on limited-time logins, seasonal minigames, and evergreen progression modes. Looking at ZZZ’s Version 3.1 lineup through that lens, the Anniversary Login Celebration functions as high-impact retention (a guaranteed S-rank pick plus W-Engine), while recurring triple-reward windows and permanent systems like Omond Research Station and Endless Tower act as long-tail engagement loops that reward steady play even after the headline festival events end.
