What you unlock from the story path
The Investigation Commission line under Operation Bagel walks you through the premise: Shepherd sends you after Joyous’s Labyrinth Carrot in Papago Hollow (the Divine Maze), Eous goes missing during the escape, and you hold the abandoned research station with survivors like Diada and Bangboo staff. Story beats sit under Primary tags. Raising the hub to Level 4 opens the final story mission. Clearing that chapter does not retire the mode. Weekly and Season Commissions keep the loop running.
Rewards snapshot
Reward type | Examples |
|---|
Standard clear loot | Polychrome, Senior Investigator Log, W-Engine Energy Module, Bangboo System Widget, Original Chip, Denny |
Season / shop exclusives | Proxy accessories (e.g. Belle: Chipi-Meow, Wise: Dubi-Meow), Pyrois Mindscapes, Pyrois W-Engine overclock mats |
Mode currency | Gear Coins (run economy), Season Coins (season shop) |
Loadout Rules: What Matters in Operation Bagel
Drive Discs stay off. Agent power in this mode comes from Mindscapes, W-Engines, and mode-only gear.
Slot | Role |
|---|
Agent Gear (per class) | Sets that agent’s level for the run. Higher tier gear unlocks harder content. |
Inventory backpack | Raises how many items you carry out. |
Anti-corruption device | Slows corruption gain and adds damage reduction. |
Blade of the Other | Unlocks Pyrois ultra skills used inside Labyrinth runs. |
Consumables | Health kits, anti-corruption medicine, Etheric Phantoms. Slot them in the loadout before you deploy; they appear on the left d-pad in combat. |
Durability burns every entry: −1 on Standard, −2 on Hard, −3 on High Risk. Broken gear needs a workshop rebuild or a Hollow drop.
Class gear often ships in two flavors. Attack gear may favor PEN Ratio on the regular blueprint and Energy Regen on the modified one. Check the icon tint before you craft.

How to Play Operation Bagel
Step 1: Open Investigation Commission → Operation Bagel and finish the intro missions until the research station facilities unlock.
Step 2: At the hub, craft Agent Gear + squad equipment in the Smart Workshop, stock consumables, and park high-value keepers in your Safe slots.
Step 3: Pick a map (Suburbs or Janus) and a difficulty. Maps keep fixed layouts. Enemy packs and loot spawns roll each run. Spawn point also rolls.
Step 4: Spend the free planning window (30 seconds) pinning far-side POIs. Distant zones host higher-level enemies and richer boxes.
Step 5: Explore, open strongboxes, grab valuables, and use Etheric Phantoms when an objective asks for them. Track icons on the big map to draw a dotted path on the minimap.
Step 6: Extract at a green exit before the timer hits zero. Clear the area, pay Gear Coins, or beat the designated boss, depending on the exit type. Boss arenas still run the clock; kill the boss and leave, or the run still fails.
Step 7: Back at the Depot Hub, bulk-sell valuables for Gear Coins, restock, repair durability, then push Weekly / Season Commissions.

Extraction, Death, and Recovery
Outcome | What happens |
|---|
One agent down | Revive at a heart-marked healing station. |
Full squad wipe or timeout | Run gear and inventory drop. Safe slot items still leave with you. |
Next entry after a wipe | Blue Collectie icon on the map marks your lost stash for pickup. |
High Risk wipe | No revive stations, no Collectie recovery. Safe slots only. |
Your inventory shows a Gear Coin value for the haul. High-value extracts feed bonus score rewards at debrief. Prioritize valuables over clutter; backpack space is the real soft cap.

Research Station Facilities
Upgrade the hub facilities to Level 4 after the story asks for Level 3. Level 4 opens access cards, wider store stock, and the late-game prep loop.
Facility | Job |
|---|
Depot Hub | Storage + bulk sell for valuables. Filter by rarity or category. |
Collectibles Database | Tracks item discovery; TVs display collection value. |
Boojee’s Store | Materials, consumables, gear, blueprints, Treasures Counter (Mindscapes / overclock items), Season Coin goods (Safe expansion, Z-rank prism blueprints). |
Smart Workshop | Craft loadout gear from blueprints. Quick Restock pulls missing mats from Boojee. |
R&D Center | Skill tree: start shields, extra storage / Safe slots, corruption resistance, Pyrois ultra upgrades, rail-running unlocks, consumable slot expansions (grab Tactics Expansion early). |
S-rank blueprints for some squad equipment and Etheric Phantoms drop in the Hollow. You cannot buy every S-rank print at the store. Z-rank (red) tactical prisms cost Season Coins; yellow S-rank prisms use Gear Coins.

Difficulties and Threats
Difficulty | Revive | Recovery run | Durability cost | Notes |
|---|
Standard | Yes | Yes | 1 | Fine for weeklies and learning routes. |
Hard | Yes | Yes | 2 | Stronger packs; still recoverable. |
High Risk | No | No | 3 | Optional Gear Coin gamble at start; prep S-tier gear first. |
Threats that eat runs:
Corruption: Caps max HP (grayed HP). Anti-corruption medicine returns 5–20% of lost max HP. Opening loot in Cacophony Soundscapes spikes the meter hard.
Ulidem (the Hound): Phantom form in Cacophony zones (killable). Stalk form after heavy looting (stand your ground or hide). Nightfall form on long High Risk runs sticks to you; break the shield to create space, then extract. You do not finish Ulidem.
Fog / phase timers: Watch Next Phase Fog Zone countdowns on the map overlay before you commit to a far extract.
How to Farm More Gear Coins and Season Progress
Sell valuables in bulk at Depot Hub after every successful extract.
Clear Weekly Commissions; progress shares with Hollow Zero bounty rewards, so pick the mode you enjoy.
Finish Season Commissions (crate opens, shield breaks, Gear Coin submissions) before the season timer ends. Season Coins buy Safe expansion and Z-rank prints.
Prep combat extracts early: clear guards so the extract timer stays comfortable when you need the exit.
Use subway / fissure gear icons and unlocked Pyrois rails to cut travel time on both debut maps.
Pin yellow Advanced Events when they spawn; they pay better than gray filler quests.
Keep Etheric Phantoms on the loadout. Season tasks and combat turns often demand specific phantoms such as Rampant Brute.

FAQ
What is Operation Bagel in Zenless Zone Zero?
Operation Bagel is the permanent Enigma of the Labyrinth extraction mode added in Version 3.1. You enter fixed 3D Hollow maps, build a mode-only loadout, loot valuables, and extract under a 25-minute timer. Supplies fund research station upgrades for later runs.
How do you unlock Enigma of the Labyrinth: Operation Bagel?
Reach Inter-Knot Level 40 and wait for the 2026/08/05 10:00 server unlock. Finish Main Story Chapter 1 Intermission if the client still lists it as a gate. Then open Investigation Commission and start the Operation Bagel primary line.
Do Drive Discs work in Operation Bagel?
No. Mindscapes and W-Engines carry over. Agent level inside the mode comes from Agent Gear. Squad equipment, consumables, and R&D talents cover the rest of the build.
What happens if you fail an Operation Bagel run?
On Standard and Hard, Collectie guards your dropped items for the next investigation, and Safe slot loot still extracts. On High Risk, a wipe burns the run except Safe contents. Timeout counts as a fail even after a boss kill if you never leave the fissure.
Is Operation Bagel better for weeklies than Hollow Zero?
Both feed the same weekly bounty track. Use Labyrinth when you want 3D loot runs and season shop progress. Use Hollow Zero when you prefer the older TV / voyage loop. Split the week however you like.
Where should Steam players top up for ZZZ banners during 3.1?
UID top-up and the Steam store both credit the same account. For a side-by-side breakdown, read Where to Buy Zenless Zone Zero Top Up for Steam.
Conclusion
Operation Bagel turns ZZZ’s Hollow loop into extract-or-lose runs: Gear Coins fund the hub, the hub funds harder loadouts, and season commissions keep the shop moving until the next major update. Bookmark this Operation Bagel guide for map, facility, and reward refreshes. When season Polychrome is not enough for Remielle, Sigrid, or anniversary selectors, buy ZZZ Monochrome on BitTopup with your UID and keep the pulls rolling.
