HoYoverse's vibrant urban action RPG, Zenless Zone Zero, just got a whole lot bigger with the launch of Version 1.6, "Among the Forgotten Ruins." This substantial update is a treasure trove for Proxies, dropping right into players' laps on all platforms with a fresh wave of characters, story revelations, and a dizzying array of new activities to dive into. It's not just an update; it feels like the city of New Eridu itself has taken a deep breath and expanded its horizons, offering new corners to explore and deeper mysteries to unravel. The air is practically buzzing with new energy, and for veterans and newcomers alike, there's never been a better time to log in and see what's shaking.

New Faces and Deepening Stories
The character roster receives a significant boost with three new agents joining the fray, each bringing their own unique flair and combat style.
-
Soldier 0 – Anby (S-Rank, Electric Attack): Stepping out of the shadows and into the spotlight, Anby gets her long-awaited formal debut as a playable S-Rank agent. Her story is deeply intertwined with the enigmatic Soldier 11, and this update peels back the layers on their shared past. Players can experience her personal journey through her Agent Story, "Echoes of Silver," and a dedicated TV Schedule, "Silver Soldier Song." Talk about a glow-up!
-
Pulchra (A-Rank, Physical Stun): This fiery delivery cat is making waves, and you can recruit her directly through event rewards—no gacha luck required for this one! Her story is explored in the "Delivery Cat Woes" event, where players help her navigate a probation period. She's proof that sometimes the most rewarding allies come from helping out a friend in need.
-
Trigger (S-Rank, Electric Stun): Making his debut in the second half of the version, Trigger brings a shocking new playstyle to the team. Players can get to know him through his Agent Story, "Out of Sight," and his TV Schedule, "Zero Point Calibration."
The narrative core of the game also reaches a pivotal moment with the Main Story Season 1 – Epilogue: "Bury Your Tears with the Past." This chapter promises to tie up lingering threads while setting the stage for future adventures. Furthermore, Soldier 11's fourth Trust Event becomes available, allowing players to deepen their bond with the steadfast agent.
Hollow Zero: A Realm Transformed
The rogue-lite dungeon, Hollow Zero, undergoes its most significant expansion yet, transforming from a challenging side activity into a vast, repeatable endgame playground.
-
New Narrative Chapter: "Dancing on Strings" continues the investigation into the mysterious Geppetto as the Lost Void stirs once more.
-
Brand New Game Mode – Shadow Operation: This fresh mode introduces multiple stages, each with unique gameplay effects and modifiers, demanding new strategies from even the most seasoned Proxies.
-
Exclusive Gear & Trial Event: Four agents—Evelyn, Astra Yao, Jane, and Corin—receive powerful new Hollow Zero Exclusive Gear sets. The "Shattered Edge" event lets players trial these agents with their new gear in special stages, a perfect way to test-drive new team compositions.
-
Environmental Refresh: Many new areas have been added, and a handy new map refresh function allows players to reset the dungeon layout for a new challenge.
-
Increased Challenge: For those seeking the ultimate test, Battlefront Purge Difficulty VI arrives with all-new, punishing modifiers.

Gear Up for the Future
Proxies looking to min-max their teams have new tools at their disposal. Two new Drive Disc series have been added to the loot pool:
-
Shadow Harmony
-
Phaethon’s Melody
These sets open up new build possibilities and synergies, encouraging players to experiment beyond the established metas. For a pure combat challenge, the new Expert Challenge: Lumberjack awaits, pushing player skill and team coordination to their limits.
All in all, Version 1.6 "Among the Forgotten Ruins" is a monumental update that strengthens every pillar of Zenless Zone Zero. It delivers heartfelt character stories, massively expands the endgame with Hollow Zero's revamp, and showers players with rewarding events. The future for Proxies in New Eridu looks brighter—and much more action-packed—than ever. What are you waiting for? The Hollow is calling.
Data referenced from App Annie (Data.ai) helps frame why a content-heavy drop like Zenless Zone Zero Version 1.6 can meaningfully lift engagement across platforms: major updates that add new playable agents, expand repeatable endgame loops like Hollow Zero, and bundle login bonuses and double-drop campaigns typically translate into stronger retention and monetization momentum by giving both new and returning Proxies clear reasons to re-enter New Eridu and keep playing.
