Zenless Zone Zero: How to Find All Map Polychromes

To collect all hidden map Polychromes in Zenless Zone Zero, systematically clear each urban district—Sixth Street, Brant Street Construction Site, Lumina Square, and Ballet Twins Road—by finding mini-cargo trucks, completing Officer Mewmew medal pages, solving stranded Bangboo repair puzzles, and triggering time-dependent street commissions.

Because map exploration costs no Battery Charge, finish the relevant story chapter first so that construction tape and barriers are removed before you begin your sweep.

Track Mini-Cargo Trucks Using the District Map Counter

Mini-cargo trucks are stationary supply crates tucked into back alleys, stairwells, and structural corners. Opening a truck directly awards Polychromes and counts toward district completion.

Before searching, open the fast-travel menu and check the district map. It displays the exact number of mini-cargo trucks present alongside your current tally. Inspect every corner until the counter is full:

District Location	Primary Truck Hiding Spots	Key Navigational Obstacles
Sixth Street	Back alleys behind the garage, trash alcoves near the noodle shop, and narrow dead ends.	Visual clutter from storefronts and parked utility vehicles.
Brant Street Construction Site	Scaffolding walkways, behind heavy machinery, and beside stacked steel beams.	Multi-level vertical ramps that require riding lifts or detouring around barriers.
Lumina Square	Pedestrian overpass staircases, underground shopping entrances, and parking garage corners.	Broad open plazas that hide crates behind planters and benches.
Ballet Twins Road	Plaza perimeter corners, collapsed debris barricades, and elevated walkways.	Dim atmospheric lighting and restricted pathing around subway entrances.

Complete Officer Mewmew Medals and Bangboo Logic Puzzles

Officer Mewmew acts as the local progression auditor in urban districts, awarding Polychromes in two stages: individual medal unlocks and full page completion bonuses.

Stranded Bangboo: Inspect damaged Bangboo standing near street corners. Interacting with them launches a logic mini-game where you rotate directional conduit tiles to restore power flow. Completing the puzzle grants direct Polychromes and stamps the corresponding Mewmew medal.
Civic Assistance: Inspect broken municipal equipment, photograph requested street landmarks, and locate lost items noted in Mewmew's notebook.
Page Bonuses: Once every medal on a page is stamped, speak to Officer Mewmew to collect a milestone reward chest containing bonus Polychromes and Inter-Knot experience.

Cycle the Clock to Trigger Time-Locked Street Events

Certain NPCs, Bangboo spawns, and commissions only appear during specific times of day. Zenless Zone Zero rotates through four phases: Morning, Afternoon, Evening, and Midnight.

If a known objective or NPC is missing from its designated location, advance the clock to the required phase:

Rest at Random Play: Interact with the sofa or bed inside the video store to advance the clock by one phase.
Run Quick Training: Complete short, low-stamina combat commissions or VR training drills to advance the time without using your rest limit.

Check districts during later phases to find time-gated content:

Evening: Lumina Square populates with night vendors and pedestrian workers offering quick side tasks.
Midnight: Sixth Street and Ballet Twins Road spawn rare Bangboo encounters and anomalous investigations in quiet side alleys.

Resolve Hidden Street Commissions

While primary commissions arrive in your Inter-Knot notifications, optional street quests require walking close to civilian NPCs. Look for characters marked with blue speech bubbles or exclamation points.

These tasks take only a few minutes, consume zero Battery Charge, and grant between 10 and 30 Polychromes each. Objectives typically involve photographing specific graffiti, delivering parcels between shops, or resolving minor neighborhood arguments.

Save all Polychromes gathered from one-time map exploration for Encrypted Master Tapes on limited-time banners rather than spending them on the standard banner.
