Celestial Nexus Intelligence Dossier Event Guide for Zenless Zone Zero

This event will take place during version 3.0 of the game, from June 17 until July 29, 2026.

This event is an introduction to the new Season 3 zone, Roscaelifer. You will have to explore the city, complete missions, and learn as much as you can about the Celestial Nexus.

In order to participate you will need to reach the Roscaelifer zone and unlock the Main Story Season 3 Chapter 1 "A Sleepwalker's Confession".

During this event, you will have to complete various commissions and missions in Roscaelifer. It is basically your typical exploration event. Expect things like kill a certain amount of new enemies, gather intel on new agents, important places, activities, and more!

You can press "Go" in the event interface to view and complete tasks. Some tasks will be unlocked as you progress through the Main Story.

We recommend you finish the main story of Roscaelifer first, as some zones or puzzles might not be available before that. Once you did, the easiest way to complete this event is to take them one by one, and follow the indications. Most challenges will immediatly lead you to what you have to do. For things like the Picture Book, once you are in the menu, you can also directly interact with the picture book you are missing and click "GO". This allows you to easily complete all the challenges withou having to search around the map for ages.

Not all challenges can be directly tracked however. For things like cargo trucks and puzzles with the drones, you will have to search for them. But keep in mind that they are all indicated on your map, so you can simply open your map and target the cargo truck you want to find.

During the event, you can earn the following rewards:

• 400 Polychrome
• 15 Bangboo Algorithm Module
• 27 Original Chip
• 40 Official Investigator Log
• 36 W-Engine Power Supply
• 630 Inter-Knot Credit
