Developer miHoYo has announced that Zenless Zone Zero version 3.1, titled “The Long Goodbye,” will launch on July 29. The update coincides with the game’s second anniversary and the official launch of the title on the Microsoft Store for PC.

Quick Facts

  • Release Date: July 29, 2026
  • New Agents: S-Rank Lumiflux Anomaly Agent Remielle Dan and S-Rank Ice Attack Agent Sigrid.
  • Anniversary Rewards: A free limited S-Rank Agent of choice, their exclusive W-Engine, 1,600 Polychromes, and 20 Signal Searches.
  • New Mode: "Enigma of the Labyrinth: Operation Bagel," a permanent seasonal game mode.

New Agents and Gameplay Mechanics

Version 3.1 introduces Remielle Dan, the first Agent to use the Lumiflux attribute. Her “Attribute Flux” mechanic allows players to sync her damage output with the attribute of the next Agent in the squad, making her highly adaptable to enemy weaknesses. She also features a “Phase Flow” state that provides team-wide buffs without requiring her to be on the field.

Sigrid, an S-Rank Ice Attack Agent, will debut in the second half of the update. Her combat style focuses on the “Aerial Patrol Spear Form,” which rewards players for maintaining a smooth output rhythm; landing Unbridled Spear skills increases her CRIT Rate and unlocks alternative attacks.

Anniversary Content and System Updates

As part of the second-anniversary celebration, players can select one of five limited S-Rank Agents—Jane, Soldier 0 – Anby, Hugo, Trigger, or Lucia—along with their exclusive W-Engine. Beyond these rewards, the update adds a "Custom Search" mechanism, allowing players to pre-designate six S-Rank Agents for their Signal Search pool to improve pulling consistency.

The update also streamlines progression with a revamped Beginner’s Guide, which replaces the previous Proxy Trial. This new interface provides tailored growth guidance and team composition recommendations based on the player’s current Inter-Knot level, alongside an increased progression speed for levels 20 through 50.

Permanent Mode and Seasonal Events

The new permanent mode, “Enigma of the Labyrinth: Operation Bagel,” tasks players with venturing into a corrupted Hollow to gather supplies. Success depends on balancing resource collection with a strict extraction time limit. The mode will follow a seasonal update cycle, sharing progress with Hollow Zero.

Limited-time festivities include the “Summer Waves Roll In” event, which grants players a free summer outfit for Lucy. Additionally, miHoYo confirmed a future crossover with Honkai: Star Rail is scheduled for this winter, and regional food collaborations with Kyuramen in the U.S. and Haidilao in Singapore are returning to mark the occasion.
