Ultimate Verdict Trial Event Guide for Zenless Zone Zero

This event will take place during version 2.8 of the game, from May 13, 2026 to June 1st, 2026.

During the event, Proxies will have to help join the HIA and participate in the latest VR challenge stages.

In order to participate you will need to reach Inter-Knot level 20 and complete the Main Story Chapter 1 Intermission.

During the event, you can speak with Zhao and Promeia on Sixth Street before heading over to the HIA to meet Lyla and access the new VR Challenge stages.

The event includes a total of 6 Alliance stages and 3 Special Offensive stages. New stages unlock gradually throughout the event, with one themed stage becoming available each day. The Special Offensive stages will also open over time rather than all at once.

Alliance stages come with their own unique Buff Effects, and Special Offensive stages use Tactical Buffs instead. These mechanics can significantly improve your performance during the challenge, so it is worth building your runs around them to reach higher ratings and scores.

For Alliance stages, you can select from a roster of trial Agents and Bangboo provided by the event. Special Offensive stages are more restrictive and only allow the specific trial Agents assigned to that challenge. Overall it is always worth to take the trial agents. It is often the new available agents, so if you wanted to try them out, this is the perfect event for that.

For this specific challenge you want to always pick Promeia when she is available as Trial Agent, because her kit fits the challenges basically. At the same time, if you weren't sure you want to pull for her, this lets you try her out in real combat.

Special Offensive stages also introduce a new scoring system focused on both damage output and combat execution. Dealing damage and performing specific combat techniques will earn points throughout the run.

Promeia plays the biggest role here, as chaining her different techniques together within a short time window builds up Technique Combos. Maintaining these combos grants additional score multipliers, but the combo state will expire if too much time passes without using another technique.

Your final score in Special Offensive stages is based on three factors:

• Damage Score
• Technique Score
• Time Coefficient tied to your clear speed

You will have to balance between technique and dealing as much DMG as fast as possible if you want to get the max rank and rewards.

During the event, you can earn the following rewards:

• 360 Polychrome
• 24 Official Investigator Log
• 12 W-Engine Power Supply
• 6 Senior Investigator Log
• 36 Original Chip
• 12 Bangboo System Widget
