Alright, fellow Proxies and Bangboo enthusiasts, gather 'round! Let me tell you about my journey through the labyrinthine menus and tempting offers of the Zenless Zone Zero Battle Pass—or as the game mysteriously calls it, the New Eridu City Fund. When I first stumbled upon it, I thought, "Great, another thing to manage in this already chaotic, neon-drenched world." But after a few seasons (and yes, a bit of real-world cash spent), I've become something of a Battle Pass connoisseur. Let me break it down for you in a way that won't make your head spin faster than a Bangboo on a sugar rush.

First things first: where is this thing? In the top-right corner of your screen, amidst all the other icons vying for your attention, you'll find a little green gem. That's your ticket to the City Fund. Click it, and voilà! You're in. It's not exactly hidden, but in the visual noise of New Eridu, it's easy to miss.

Now, the core of it all is the free track. Everyone gets this, no Dennies or real money required. It's a solid lineup of goodies:

• Crafting materials for your W-Engines (because who doesn't love a souped-up weapon?)

• Upgrade bits for Drive Discs

• Goodies to enhance your Agents' attributes

It's a nice, steady drip-feed of resources that helps you keep up with the game's challenges. But let's be real—the free track is like the demo version of a Bangboo. It's functional, but you're always eyeing the shiny premium model.

Ah, but then there's the paid track. This is where things get interesting (and where your wallet might start sweating). To unlock it, you need to choose one of two paths: the Growth Plan or the Premium Plan. Think of it as choosing between a reliable sedan and a turbo-charged sports car. Both get you places, but one does it with more flair (and a heftier price tag).

Before you even think about paying, check the season timer! In the bottom-left corner of the Battle Pass menu, you'll see exactly how much time you have left to grind. Seasons in 2026 are still a decent length, but if you're a casual player who logs in once a week to pet your virtual Bangboo, you might want to stick to the free track. No shame in that!

How do you level this thing up? Through City Fund EXP, earned by completing Expansion Tasks. You can find these by hitting the 'Expansion Tasks' tab in the top-right of the Battle Pass screen. The tasks break down like this:

Task Type	Refresh Schedule	My Personal Feeling About Them
Daily Tasks	Every day at 4 AM server time	Quick, easy, my morning coffee ritual. ☕
Weekly Tasks	Every Monday at 4 AM server time	A bit more involved, my weekend project.
Seasonal Tasks	Last the entire season	The big, chunky goals that give a real sense of achievement. 🏆

You claim your EXP rewards right from this screen. But here's the catch—there's a weekly cap. You can only earn 10,000 City Fund EXP per week from Daily and Weekly tasks. So, no, you can't no-life it on a Sunday and max out the pass. The game gently encourages consistent play, not marathon sessions. You can see your progress toward this limit on the left side of the main menu.

Now, what if you're running out of time or just really, really want that Level 30 reward now? Well, my impatient friend, there's a Purchase Levels option. It's on the left side of the menu. Click it, and a window pops up showing you how many levels you can buy and, more importantly, what it'll cost you in Polychrome. It's not cheap. This is the "I have more money than time" button. Use it wisely, or you'll be eating instant noodles for a week.

Let's talk about the paid plans. First up, the Growth Plan. As of 2026, this is the budget-friendly option, usually around $9.99 USD or regional equivalent. What do you get?

• Access to the entire second reward track (the good stuff).

• A Great Builder's Certificate when you hit Level 30 (more on this later—it's a big deal!).

• A nice bundle of bonuses upfront:

• 780 Polychrome 💎

• 4 Encrypted Master Tapes 🎵

• 1 Hamster Cage Pass (yes, really)

• 10 Hi-Fi Master Copies

To buy it, look for the 'Unlock New Eridu City Fund' button in the bottom-right corner of the Battle Pass screen.

Then there's the Premium Plan. This is the deluxe package. It costs more (around $19.99 USD on discount, normally a bit higher), but oh boy, does it come with perks. You get everything from the Growth Plan, plus:

• An instant 10-level boost on your Battle Pass. Talk about a head start! 🚀

• Extra goodies:

• 200 additional Polychrome

• 1 Eridu Tycoon (sounds fancy, right?)

• 1 Lucky Start Namecard (for bragging rights)

• 1 'Growth Plan' Silver Piggy Bank 🐷

• 5 Ether Batteries

It's the choice for the serious player who wants to maximize their season and get a shiny boost right out of the gate. The purchase process is the same—find that unlock button and select 'Premium Plan'.

Now, the crown jewel for many: the Great Builder's Certificate. If you buy either paid plan and grind your way to Battle Pass Level 30, this beauty is yours. It lets you pick any one W-Engine from a special selection in the City Fund Benefits menu. You find that menu via a tab in the far top-right corner of the Battle Pass screen. This is a huge deal for optimizing your build for your favorite Agent.

WARNING: This certificate has an expiration date! 🗓️ It vanishes when the season ends. Do not hoard it like a dragon with gold. Use it before the timer hits zero, or you'll be kicking yourself.

So, is it worth it? Let me give you my totally unbiased, slightly-swayed-by-shiny-rewards opinion:

• For the Hardcore Player: Absolutely. The Premium Plan's level boost and the Certificate for a top-tier W-Engine can significantly power up your roster. The extra Polychrome and materials are always welcome.

• For the Regular Player: The Growth Plan is a fantastic value. The second track's consistent rewards and that Certificate are a great return on a modest investment if you play regularly.

• For the Casual/Very Casual Player: The free track is perfectly respectable. Don't feel pressured to pay. Enjoy the story, explore New Eridu, and if you find yourself playing more and more, then reconsider next season.

Ultimately, the New Eridu City Fund is a well-designed system. It rewards consistent play, offers clear value for money if you engage with it, and doesn't lock essential power behind a paywall. Just remember to watch that season clock, spend your Certificate, and maybe think twice before blowing all your Polychrome on level skips. Now, if you'll excuse me, I have some Weekly Tasks to complete before the reset. My Bangboo won't upgrade itself!
