In the bustling, chaotic streets of New Eridu, where Hollows pose a constant threat, a different kind of civic duty calls. Beyond the main storyline and intense combat commissions, players of the acclaimed action RPG Zenless Zone Zero can engage in community-focused activities that offer substantial rewards and deepen the connection to the city's districts. Central to these side endeavors is the enigmatic Officer Mewmew, a feline authority figure who seeks the help of reliable Proxies. By assisting Officer Mewmew with various urban tasks, players can earn Officer Mewmew Medals, a key currency for progression and resource acquisition. As the game continues to evolve in 2026, understanding the mechanics of Mewmew Challenges remains crucial for any Proxy looking to maximize their potential and contribute to the betterment of New Eridu.
🎯 How to Acquire Officer Mewmew Medals: Understanding Mewmew Challenges
Officer Mewmew Medals are the direct reward for completing tasks known as Mewmew Challenges. These challenges are diverse community projects scattered across every explorable city block in New Eridu. Each district visited will present a fresh set of objectives from the diligent officer. The challenges themselves fall into several distinct categories, encouraging players to explore every nook and cranny of the urban landscape:
-
Completing City Commissions: These are side quests marked by distinctive blue exclamation points on the map. They often involve helping citizens with various problems, from simple deliveries to more complex investigations.
-
Finding HIA Commemorative Coins: Scavenger hunts that task players with locating hidden coins. Some areas, like the Brant Street Construction Site, feature challenges for finding half the coins and another for collecting all of them.
-
Locating Mini Cargo Trucks: Search missions to find lost or hidden cargo vehicles. For instance, Sixth Street has a challenge to find six specific Lost Cargo Trucks.
-
Assisting or Repairing Bangboo: Helping the city's robotic companions, often involving puzzle-solving or simple interactions to get them back on track.
Each challenge comes with a brief description to guide players. Some descriptions hint at specific locations, time-of-day requirements, or prerequisite actions. Notably, not all challenges are visible initially. Many are concealed behind question marks, only unlocking through specific triggers. These triggers can include:
-
Advancing the main narrative of Zenless Zone Zero.
-
Completing other, related Mewmew Challenges first.
-
Reaching a certain Inter-Knot level or story chapter milestone.
Furthermore, city blocks often contain multiple pages of challenges. Accessing subsequent pages requires both progression in the main story and a sufficient number of completed challenges. For example, unlocking the second challenge page for Sixth Street necessitates earning 10 Mewmew Medals and finishing the Chapter 2 Main Story. This layered structure ensures a steady stream of content aligned with player progression.
📦 The Bountiful Rewards of Mewmew Challenges
Completing Mewmew Challenges is far from a purely altruistic act. Officer Mewmew generously rewards diligent Proxies with a wealth of valuable resources essential for character and equipment development. Every completed challenge grants the following rewards:
| Reward Type | Primary Use | Approximate Quantity per Challenge |
|---|---|---|
| Dennies | In-game currency for purchases and upgrades. | Varies |
| Polychromes | Premium currency for acquiring Master Tapes and other rare items. | A small, consistent amount |
| Officer Mewmew Medal | Track progress and unlock further challenge pages. | 1 |
| Official Investigator Logs | Grants 600 EXP to an Agent. | Sometimes |
| W-Engine Power Supplies | Grants 600 EXP to a W-Engine. | Sometimes |
| Exploration Observation Data | Used for various progression systems and research. | 1 piece |
| Inter-Knot EXP | Increases the player's overall account level. | A small amount |
A critical note for 2026 players: You must manually visit Officer Mewmew to collect your rewards after finishing a challenge. Only upon collection will you receive the associated Exploration Observation Data and other items. This data is particularly valuable for late-game progression systems and unlocking deeper lore entries about New Eridu. The steady drip of Polychromes is also invaluable for free-to-play players aiming to expand their roster of Agents through Master Tape pulls.
🚀 Unlocking Officer Mewmew: Your First Steps as a Civic-Minded Proxy
New Proxies cannot immediately access these challenges. Unlocking Officer Mewmew requires completing a specific sequence of early-game activities. The process begins after finishing the Prologue and the Chapter 1 Story Commission titled 'Earlybird Ticket to Safety'. Following this, players must engage in a series of introductory world activities:
-
Display the photos from your memory board onto the wall in your video store.
-
Use the bed to go to sleep and advance time.
-
Visit the HIA Club and attempt a new challenge there.
-
Return to your video store and converse with your sibling.
-
Finally, either assist a citizen on the street or complete the newly available Combat Commissions.
Upon completing these steps, a cutscene will trigger where your sibling comments on unusual activity outside. Stepping out introduces you to Officer Mewmew, who has a predicament: a Bangboo with a damaged logic circuit is missing. The solution is nearby—the Bangboo is located behind the newspaper stand opposite your shop. A simple interaction and an easy puzzle involving turning its transmitters will resolve the issue, leading to another scene with the grateful officer.
Impressed by your reliability and lawful conduct, Officer Mewmew deems you the perfect candidate to assist with community projects across New Eridu. From this moment, the Mewmew Challenge menu for Sixth Street becomes accessible. As you explore new city blocks in your journey, Officer Mewmew will appear in each one with a fresh set of localized challenges. Players can easily track the officer's location via the navigation menu, which even offers a fast-travel option directly to them—a quality-of-life feature highly appreciated by veterans in 2026.
