Holographic Onslaught Arena Event Guide for Zenless Zone Zero

This event will take place from June 13, 2025 until June 30, 2025.

In order to participate in Holographic Onslaught Arena event you need to reach Inter-Knot Level 22 and unlock Expert Challenge in Chapter 2 of the Main Story.

In Holographic Onslaught Arena Event you have to head to the HIA to test out the new VR features! Talk to Ju Fufu in Failume Heights and head to the HIA Club to find Lyla.

During the event, you will have access to five Alliance Stages, five Frontline stages, and three Special Offensive stages. A new themed stage will be unlocked each day.

Every time you complete the Alliance stage, you unlock the corresponding Frontline stage. The Special Offensive ones unlock over time.

Each stage also has a specific Tactical Buff mechanic. Try to take advantage of it.

During the Alliance and Frontline stages, you can either pick your own Agents, or try out the trial Agents and Bangboo that are provided.

We recommend you use the provided Agents, they are really are tailored for each of the challenges and the buffs. For example, the second Alliance stage, Abloom Alliance requires you to specifically trigger the Abloom effect of Vivian, which can only be done if you use her. You can of course use your own Vivian if you have her, but for those who don't, use the Agents provided by the game for each challenge. It just makes it overall easier, and allows you to test Agents you may not have.

On the other side, during the Special Offensive stages, you can only use Yixuan and Ju Fufu. They will both be provided, you do not have to pull for them.
