The New Eridu City Fund returns in Zenless Zone Zero Version 3.3 with exclusive cosmetics, Polychromes, upgrade materials, and an A-Rank W-Engine selection reward. Players can progress through the free Basic Plan, unlock the Growth Plan for additional rewards, or choose the Premium Plan for extra bonuses and faster progression.
If you need Monochrome to buy the New Eridu City Fund, TOPUPlive can help you top up ZZZ Monochrome, including 60 Monochrome for $0.99 and 300+30 Monochrome for $4.99, so you can quickly prepare resources for his banner.
The City Fund offers three main progression options: Basic, Growth, and Premium. Each option provides a different level of access to rewards.
The Basic Plan is automatically unlocked at the start of the City Fund season. You can complete Expansion Tasks, earn Fund EXP, and claim the rewards available on the free track without purchasing anything.
This is the most suitable option for free-to-play players or anyone who wants to save resources for limited-time Agents and W-Engines.
Even if you do not plan to spend money, it is worth completing the available tasks. You can make progress toward the Fund's reward levels and collect free materials while playing normally.

The Growth Plan unlocks a second set of rewards on top of the Basic Plan. According to the official announcement, purchasing it immediately grants:
As you increase your Fund Level, you can also claim additional rewards, including the exclusive Horror Tale: Childhood Edition namecard, upgrade materials, and a Great Builder's Certificate at the required level.
The Growth Plan is worth considering if you regularly complete daily and weekly activities and expect to reach the higher Fund levels before the season ends.

The Premium Plan includes the benefits of the lower-tier paid track and provides additional instant rewards, including:
The Premium Plan is designed for players who want additional rewards and faster Fund progression. However, its value depends on how much you play and whether you actually need the extra materials and cosmetics.
Players who have already purchased the Growth Plan can upgrade to the Premium Plan. Before upgrading, check the in-game purchase screen to confirm the price and additional benefits available for your account.
The City Fund combines premium currency, cosmetics, equipment-related rewards, and character progression materials. Here are the rewards worth paying attention to.

Polychromes are one of the most useful rewards for players planning to pull limited-time Agents or W-Engines.
The Growth Plan immediately grants 680 Polychromes, while the Premium Plan provides an additional 208 Polychromes in its instant rewards. If you are saving for an upcoming banner, these resources can supplement your existing savings.
However, the City Fund should be treated as one part of a broader resource plan. Free events, daily activities, and other version rewards can also contribute to your total Polychrome income.

The Growth Plan immediately grants the Trick or Treat! avatar. The paid progression track also includes the exclusive Horror Tale: Childhood Edition namecard.

These cosmetics are primarily for players who enjoy customizing their profiles. If you care more about combat performance than collection items, consider how much value you personally place on these rewards before purchasing a paid plan.

One of the most practical rewards is the Great Builder's Certificate.
After unlocking the Growth Plan or Premium Plan, reaching City Fund Level 30, and claiming the certificate, eligible players can choose one W-Engine from a selection of seven options. The selection includes the A-Rank W-Engine Bloodmarrow Coffer.
This can be useful if you want an additional W-Engine for a suitable Agent. However, the best choice depends on your roster, existing equipment, and preferred team compositions.
Remember: The Great Builder's Certificate is a time-limited reward for the current City Fund period. It will not carry over to the next season and will expire automatically if you do not use it within the allowed period. Claim and use it before the deadline.
The City Fund also provides resources for developing Agents, W-Engines, and Bangboo. These materials can reduce some of the grinding needed to strengthen your roster.
The Premium Plan offers additional instant materials, including a W-Engine Microcontroller Unit, a Resonating Core, and Ether Batteries.
The exact value of these resources depends on your current progression. Players with several Agents still needing upgrades may benefit more than players who already have their main teams fully developed.
After you get the upgrade materials, you could read ZZZ Severian Build Guide: Kit, Best W-Engine, Drive Discs & Teams | Zenless Zone Zero 3.3 and ZZZ 3.3 Phoenix Build: Best W-Engine, Drive Discs, Teams & More to konw about the new characters.
The main difference between the plans is how much additional content you receive and how quickly you can progress.

|---|---|---|---|
Purchase required | No | Yes | Yes |
Basic rewards | Yes | Yes | Yes |
Additional paid-track rewards | No | Yes | Yes |
Instant Polychromes | No paid-plan bonus | 680 | 680 from Growth Plan + 208 additional |

If you need Monochrome to buy the New Eridu City Fund, TOPUPlive can help you top up ZZZ Monochrome, including 60 Monochrome for $0.99 and 300+30 Monochrome for $4.99, so you can quickly prepare resources for his banner.
The best plan depends on your playtime, resource needs, and interest in exclusive cosmetics.
If you prefer not to spend money, the Basic Plan is the obvious choice. You can still earn its available rewards by completing Expansion Tasks.
Save your budget for a limited-time Agent, a W-Engine, or another purchase that better fits your priorities.
The Growth Plan is worth considering if you play consistently and can progress through the paid reward track.
Its 680 instant Polychromes are a clear benefit, while the exclusive avatar and additional progression rewards provide further value. The Great Builder's Certificate can also be useful if you reach Level 30 and select a W-Engine that suits your roster.
Before purchasing, estimate how many Fund Levels you can realistically complete before the season ends.
The Premium Plan is more suitable for players who value the additional cosmetics, upgrade materials, and faster progression.
However, the extra rewards are not automatically worth the additional cost for everyone. If you only want Polychromes, compare the full package against your other spending options. If you also need the materials and cosmetics, the Premium Plan may be a better fit.
The Growth Plan immediately grants 680 Polychromes and the exclusive Trick or Treat! avatar. Additional rewards are available as you progress through the paid track.
The Premium Plan provides an additional 208 Polychromes, a menu decoration set, a W-Engine Microcontroller Unit, a Resonating Core, and Ether Batteries as instant rewards, alongside the benefits of the lower-tier plan.
No. The certificate is a time-limited reward for the current City Fund period. It will expire if it is not used within the allowed time, so make your selection before the deadline.
Yes. According to the official announcement, players can continue completing Expansion Tasks and claiming rewards while the event remains active. However, purchasing the Growth Plan, Premium Plan, and Plan Upgrade closes one hour before the event ends.
The ZZZ 3.3 New Eridu City Fund offers free progression rewards alongside paid plans that provide additional Polychromes, cosmetics, upgrade materials, and a selectable A-Rank W-Engine reward.
The Basic Plan is suitable for free-to-play players, while the Growth Plan is worth considering for regular players who want more resources. The Premium Plan is best reserved for players who also value its extra materials, cosmetics, and faster progression.
Check your Fund Level, review the in-game price, and use the Great Builder's Certificate before it expires. For more Zenless Zone Zero guides and top-up information, follow TOPUPlive.
