Hollows are Zenless Zone Zero’s (ZZZ) signature endgame dungeons, packed with roguelike strategy, tough enemies, and some of the game’s best loot. Progressing through Hollow Zero and other advanced Hollow zones unlocks huge rewards and fuels long-term account growth.

How to Unlock Hollow Zero & Hollow Zones

To access Hollow Zero, complete Chapter 1 – Intermission (“Art of War Kite Edition”) in the main story. Visit Scott Outpost Interior, locate the big tent, and meet Ray, this unlocks your first Hollow zone (IGN Hollow Guide, GameWith, TopUpLive Hollow Guide).

Progression pathway for Hollow zones:

Each zone features tougher enemies and more demanding completion requirements.

Upgrading & Progressing Hollow Zones

  • Unlock Nodes: In “Lost Void” mode, purchase adjacent nodes to open new paths. Upgrading nodes costs Shadow Crystals; higher levels grant stronger buffs (TheGamer Lost Void Guide).
  • Expertise Points: Spend these on fully upgraded nodes for an extra 10–20% boost.
  • Zone Upgrades: Completing missions and bounties raises your License Level, unlocking higher zone difficulties and better rewards. Max out buffs and prioritize critical nodes for top drops.
  • Hollow Pressure & Corruption: Each move in Hollow increases Pressure; plan the shortest routes and use Safe Zones to avoid debuffs (UltimateGacha Hollow Tips).

Endgame Rewards

Clearing Hollow Zero and its upper zones yields:

  • Ascension materials
  • Resonium (grid-based perk upgrade currency)
  • Master Tapes, Encrypted Master Tapes (gacha pulls)
  • Rare gear & event-limited currencies (Game8 Rewards Guide)
  • Achievements tied to Observation Data and event tiles

Fast Progression Tips

  • Deploy your strongest agent first, only one is available when starting zones
  • Upgrade characters before moving to new Hollow zones; difficulty spikes are significant
  • Clear commissions and side quests for quick unlocks
  • Repeat Hollow Zero runs weekly for max rewards; reach monthly reset limits on Investigation Points (GameWith)
