Zenless Zone Zero Going Green for Everyone: Overview

The “141 Going Green For Everyone” event in Zenless Zone Zero is a special item exchange event that encourages players to take part in New Eridu’s environmental protection campaign by recycling used batteries. As part of the city’s initiative to promote sustainability, players will assist Sjal, a key NPC overseeing the campaign, by gathering these discarded batteries and exchanging them for a variety of valuable rewards. This event not only provides players with useful in-game resources but also immerses them in the world of Zenless Zone Zero, highlighting the futuristic metropolis’s ongoing efforts to maintain order and balance amidst the chaos of the Hollows.

Running from February 26, 2025, to March 10, 2025, the “141 Going Green For Everyone” event is a limited-time opportunity for players to collect event-exclusive materials and earn valuable rewards through active participation. This event ties into New Eridu’s environmental campaign, where players assist Sjal in collecting and recycling Used Batteries to support sustainability efforts within the city. Engaging in the event daily allows players to unlock a variety of rewards, including Polychrome, Dennies, Investigator Logs, W-Engine Energy Modules, and more.
However, before players can take part in the event, they must first meet specific requirements to ensure they have progressed far enough in the game to access event-related content. The first requirement is reaching Inter-Knot Level 15, which signifies a sufficient level of advancement in Zenless Zone Zero and ensures players have access to the necessary in-game mechanics. Additionally, players must complete the Agent Story “Mole in the Hole (I)”, a prerequisite mission that introduces key narrative and gameplay elements related to the event. This ensures that participants are familiar with the Hollows, Agents, and other aspects of the world of New Eridu before taking on the event’s tasks.
Once these conditions are met, players can begin collecting Used Batteries by consuming Battery Charge through various in-game activities. These batteries can then be exchanged with Sjal at the 141 Convenience Store in Reverb Arena for rewards, with new exchange opportunities unlocking each day. Since the event is time-sensitive, it’s crucial to start gathering batteries as soon as possible to avoid missing out on potential rewards. Players who actively participate throughout the event can unlock seven sets of rewards and claim an exclusive bonus reward by submitting at least five Used Batteries during the event period.
By taking part in the “141 Going Green For Everyone” event, players not only gain valuable resources to enhance their Agents and Bangboos but also contribute to an in-game initiative that highlights New Eridu’s environmental efforts, making it a rewarding experience both in terms of gameplay and world-building.
How to Participate:
To participate in the “141 Going Green For Everyone” event in Zenless Zone Zero, players must collect Used Batteries and exchange them with Sjal at the Reverb Arena for various rewards. The event introduces a simple yet engaging system where players contribute to New Eridu’s environmental initiative while earning valuable in-game items.

Each day, players can obtain a Used Battery by consuming Battery Charge for the first time that day. These Used Batteries come in different types, such as Bangboo Batteries, Ether Batteries, and Special-Model Batteries. The amount of Battery Charge used does not impact the reward—players simply need to spend any amount to receive a Used Battery once per day.

Once a Used Battery is obtained, players must head to Reverb Arena and locate Sjal, who is stationed at the 141 Convenience Store. As part of the 141 Environmental Campaign, Sjal is in charge of collecting these batteries and offering rewards in exchange for them. Interacting with her will allow players to submit their Used Batteries, which can come in different types such as Bangboo Batteries, Ether Batteries, and Special-Model Batteries. Each exchange provides valuable in-game rewards, making it beneficial for players to participate daily.
New reward sets are unlocked daily at 4:00 (server time), but players must complete the previous day’s exchanges before accessing the next set. This means that missing a day will delay progress, so consistent participation is highly encouraged. Throughout the event’s duration, players can unlock a total of seven sets of rewards, each offering different resources such as Polychrome, Dennies, Investigator Logs, W-Engine Energy Modules, Bangboo System Widgets, and Specialized Chips.
By engaging in the event each day and exchanging Used Batteries, players not only earn valuable materials to enhance their Agents and Bangboos but also contribute to the 141 Environmental Campaign, reinforcing the theme of community effort within New Eridu.

Additionally, players who submit a total of five Used Batteries during the event will receive an Exclusive Reward, making it beneficial to engage in battery collection every day. Since the event is time-limited, players should make sure to log in daily, use their Battery Charge, and exchange Used Batteries promptly to maximize their rewards before the event ends.
