Rather than walking around the map, Zenless Zone Zero utilizes a unique Hollow Exploration feature, showcasing a board game-like structure. Various events are scattered around this dimension, either leading to valuables or dangerous showdowns. We’re here to guide you through ZZZ’s Hollow Exploration, including each icon’s meaning on the map.
What is Zenless Zone Zero Hollow Exploration?
You’ll typically enter ZZZ’s Hollow Exploration mode when starting a Story, Exploration, or Combat mission. Players must move their Bangboo across monitors to reach specific spots in the dimension. Some events trigger boss fights, but there are a few helpful blocks, like Observation Data and Supply Boxes. These materials will provide you with rewards, which can be helpful for Agent upgrades.
Some Hollow locations present higher Pressure levels, hindering your party’s performance. Keep track of this gauge to ensure the team is in good shape. Additionally, if you want to fast-track things, use the Accelerated Playback Mode to speed up those long, drawn-out texts.
All Zenless Zone Zero Hollow Exploration icons
There are a variety of events you can encounter in the Hollow. While some can benefit you, others can inflict damage on your team. Thus, knowing what each icon means is crucial before stepping on top of it. To better understand this, we’ll break down all the Hollow Exploration icons in Zenless Zone Zero. However, we’re still working our way through this list, so stay tuned for more updates.
