Zenless Zone Zero Version 2.7 Launches March 24 with Hollow Champion Competition

Hollow Champion Competition Takes Center Stage#

According to a HoYoverse press release, Zenless Zone Zero Version 2.7 "Champions Never Fall to the Past" launches on March 24, 2026. The update centers on the Hollow Champion competition hosted by TOPS, bringing together factions including the Cunning Hares, Sons of Calydon, Public Security's Metropolitan Order Division, and former Calydon's Sweepers.

This marks a significant shift in ZZZ's storytelling approach. Previous updates have largely focused on individual faction storylines or smaller-scale conflicts, but 2.7 appears to be positioning multiple groups in direct competition with each other. The involvement of TOPS (the mega-corporation that's been lurking in the background since launch) suggests we might finally get more insight into New Eridu's power structures and how Hollow exploration has become commercialized.

The faction lineup is particularly interesting. Having both current and former Calydon members competing against each other could create some compelling character moments, especially given the Sons of Calydon's emphasis on honor and tradition. Meanwhile, Public Security's participation raises questions about whether this is official business or if certain officers are competing on their own time, which could have implications for the ongoing tension between institutional authority and independent Proxy operations.

Two New Agents Join the Roster#

The update introduces two new playable agents: Nangong Yu and Cissia. Cissia is an S-Rank Electric Attack agent from the Metropolitan Order Division, adding a new high-tier option for Electric-focused team compositions.

Cissia's arrival is notable for Electric mains who've been working with a relatively limited roster compared to other elements. Her Metropolitan Order Division affiliation suggests she'll likely synergize well with Zhu Yuan, potentially opening up new team-building options for players who've invested in Public Security characters. The fact that she's positioned as an Attack agent rather than Support or Stun also indicates HoYoverse is addressing the element's need for more damage-focused options beyond the existing lineup.

Details on Nangong Yu remain sparse in the announcement, but the name and timing suggest they could be connected to the Hollow Champion competition's narrative. Given ZZZ's pattern of releasing agents tied to major story beats, Yu might represent one of the competing factions or serve as a key figure in TOPS' organization of the event.

Players will face a new enemy called Black Wolf Romeul, which features a Corruptive Barrier ability that increases both CRIT Damage Resistance and Interruption Resistance, potentially requiring strategic adjustments to standard DPS rotations.

This enemy design signals a deliberate counter to the CRIT-stacking meta that's dominated endgame content since launch. Players who've built their entire roster around maximizing CRIT Rate and CRIT DMG will need to either diversify their stat priorities or lean harder into characters with built-in resistance shred. The Interruption Resistance component is equally significant, as it threatens to invalidate the Daze-focused strategies that have been core to ZZZ's combat identity.

Expect community theorycrafters to start exploring alternative damage sources like Anomaly builds, Pen Ratio optimization, or characters with true damage components. This could shake up tier lists and make previously overlooked W-Engines suddenly relevant. It's a smart design choice that prevents the meta from stagnating, though it'll likely frustrate players who just finished min-maxing their current builds.

Events and Rewards#

Version 2.7 brings themed activities to the Simmer Hotpot Restaurant and updates to the Simulated Battle Trial in New Eridu. Competitors can earn rewards including the rare Porcelloy W-Engine and various victory honors through participation in the Hollow Champion events.

The Porcelloy W-Engine being offered as an event reward is significant, as these limited equipment pieces typically define character builds for months after their introduction. Depending on its stats and passive effects, it could become a must-have for specific agents or team compositions. Free-to-play and low-spender players should prioritize these events, as gacha W-Engines can be prohibitively expensive to acquire through standard channels.

The Simulated Battle Trial updates suggest HoYoverse is continuing to refine its endgame loop. These trials have been the primary testing ground for optimized builds and team synergies, so changes here could indicate new mechanics, enemy types, or scoring systems that reward different playstyles. If the updates tie into the Hollow Champion theme, we might see competitive leaderboards or faction-based scoring that encourages players to engage with characters they've previously ignored.

The update positions itself around competitive themes, with HoYoverse emphasizing that "Champions gather for glory as the Hollow Champion competition is in full swing." This framing aligns with ZZZ's ongoing effort to build out New Eridu as a living world where Hollow exploration isn't just dangerous work but also a spectacle that draws crowds and competitors. It's a natural evolution of the setting's cyberpunk-meets-urban-fantasy aesthetic, where everything from survival to heroism gets commodified and turned into entertainment.

Are you planning to pull for Cissia, or are you saving your Polychromes for a future banner? With limited details on Nangong Yu and potential reruns on the horizon, it's a tough call for anyone managing their gacha budget.
