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.
