Special Disaster Control Squad Event Guide for Zenless Zone Zero

This event will take place during version 2.7 of the game, from April 03, 2026 to April 20, 2026.

During the event, Proxies can head to Sixth Street and talk with Hoshimi Miyabi, then head to HAND Headquarters to find A-Xin, and participate in the new event 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, low levels of Ethereals have appeared all over the Hollows, and someone needs to be check it out and solve the crisis! You will be able to use 3 teams in specific relay battles in order to complete those commissions.

A new themed stage unlocks each day, for a total of five stages.

To start the event, head to Sixth Street and find Hoshimi Miyabi.

You will head to HANDS and talk to A-Xin to start the first stage.

In these stages, you will bring three separate two-character squads and fight continuously for up to three minutes. Enemies spawn non-stop, and defeating them increases your score. At the end, your performance is rated based on the total score you achieved.

Each stage comes with its own unique buffs. By dealing damage or completing timed objectives with your squads, you will fill a Charge Bar. Once it is full, you will automatically switch to the next squad in rotation. Every swap upgrades the stage buff, unlocking stronger effects and new mechanics that help you push for higher ratings.

Before starting a stage, you can also get a higher score multiplier, but that involves enemies will be harder to beat as well:

• 1x means Monster HP is lower, but the score is multiplied by 1. Enemies will be level 55 here.
• 2x means Monster HP is higher, but score is also multiplied by 2. Enemies will be level 60 here.

If your squads are leveled and properly equipped, you should have no issue completing stages in x2. However, keep in mind that there are no specific rewards for completing the stages in higher difficulty, so if you do not want to bother, just keep it in x1. You do have to make sure you reach a total of 150 000 points in order to obtain the Title, so if you are short on points, x2 should help you reach the proper amount.

When selecting your squad, you can check the squad tips in order to know the best types of teams for this stage (for example the first stage recommends Anomaly Agents).

You can pick your own squad and buffs, or simply select Quick Recommend if you want the game to pick for you. There are some trial Agents in this event, so picking quick recommend will usually select the trial agents and the proper buffs. Those agents typically are made to help you complete each stage, so it is always a good idea to simply pick those.

During the event, you can earn the following rewards:

• 300 Polychrome
• 15 Senior Investigator Log
• 60 Original Chip
• 30 Bangboo System Widget
• 100 000 Denny
• "Anti-Disaster Specialist" Title
• 1 Tuning Calibrator
