Zenless Zone Zero is preparing for another major update, and this one comes with something PC players have been waiting for: a Steam release.

HoYoverse has announced that Version 3.3 will launch on October 21, 2026, introducing two new playable agents, Phoenix and Severian, alongside additional combat content and a new chapter of the game's ongoing story.

The update will also bring Zenless Zone Zero to Steam, expanding the game's PC availability beyond its existing distribution channels.

For longtime players, the new agents and story content are the main attractions. For newcomers, the Steam release provides another way to jump into New Eridu.

Phoenix and Severian Headline the Version 3.3 Banners

The update introduces two S-Rank agents with different combat specialties.

Agent	Details
Phoenix S-Rank	Attribute: Fire Specialty: Anomaly Banner Phase: First Half Phoenix is the second-in-command of the Krampus Compliance Authority in combat. Her Core Skill, Nirvana, allows subsequent Anomaly damage against affected enemies to trigger critical hits. She can also activate Rebirth after receiving a fatal blow, returning to combat with full health. Her signature S-Rank W-Engine is Plume of Rebirth.
Severian S-Rank	Attribute: Wind Specialty: Attack Banner Phase: Second Half Severian is a senior commissioner at New Eridu Public Security. His combat style features automatic dodges and counterattacks, with certain skills building energy for powerful consecutive slashes.

New Mech Combat Comes to Zenless Zone Zero

As we reported before, Version 3.3 introduces a new gameplay feature that allows players to pilot combat mechs.

These machines are used to infiltrate enemy bases while disguised, combining melee attacks with ranged combat. The new mechanics offer a different approach from the game's regular agent-based battles.

The update also introduces improvements to combat tutorials and squad-building guidance.

Certain permanent combat modes will provide recommendations based on party size, character upgrades, and team synergy. Players will be able to open relevant guides directly from the squad configuration screen.

The Story Returns to Roscaelifer

The conflict surrounding Roscaelifer's sky island escalates in Version 3.3.

With access to Booastrum restricted, the occupied Quietude Isle skyport becomes the only route back to the island.

Phoenix and Severian are forced to work together despite their differences, while the Proxy travels alongside Lindverne to investigate the mystery surrounding the three Sunbringers and their Karma Cores.

The update continues the ongoing story rather than introducing an unrelated adventure, giving returning players another reason to catch up before October 21.

Zenless Zone Zero Version 3.3 Release Details

Zenless Zone Zero Comes to Steam on October 21

The Steam release is another notable addition to Version 3.3.

Zenless Zone Zero will become available through Valve's PC storefront on October 21, alongside the update's launch on existing platforms.

The game will remain free to play.

Steam availability gives players another distribution option and makes the game accessible through Steam's library and community features.

HoYoverse is also expanding its Discord integration. Beginning October 21, players will be able to link their accounts to synchronize game activity with their Discord profiles.

However, players using the older Discord account-linking service should note that its existing functions will be discontinued on October 14 ahead of the replacement system. Previously claimed rewards will not be affected.

Free Rewards and Other Version 3.3 Changes

Players will be able to claim 10 Encrypted Master Tapes and 10 Boopons through the update's check-in events.

HoYoverse is also introducing more accessible character tutorials, improved squad configuration advice, and clearer Inter-Knot Reputation progression reminders.

These changes should make it easier for newer players to understand team-building and progression, particularly those joining through Steam.

Version 3.3 launches October 21, 2026. Players can find additional details through the official Version 3.3 overview and HoYoverse's announcement.
