Zzz… Oh Wait, It’s 25 GB! Zenless Zone Zero 3.1 Pre-load Mayhem Arrives

It is that magical time again, Proxies. The day when your internet connection weeps, your storage groans, and the official Zenless Zone Zero channels buzz with a mix of excitement and sheer terror over download sizes. Version 3.1 is revving its engines on the horizon, and the pre-download window has swung wide open. If you ever wanted to test whether your solid-state drive truly has "enough free space," well, now is the moment of truth.

The developers have lit the beacon for pre-download starting July 27, 2026, at 12:00 (UTC+8), and the gates will remain open until the maintenance itself begins on July 29 at 05:50 (UTC+8). That is a generous 42-hour cushion to wrestle with gargantuan files. Just how gargantuan? Let’s put it this way: if you are on a PC, you are staring down an approximately 11 GB chunk. Mobile players on Android and iOS get off relatively easy with a 7 GB download. But console folk, brace yourselves. PlayStation 5 or PS5 Pro owners are looking at a staggering 25 GB. Xbox Series X|S users, you are the heavyweight champions with a jaw-dropping 26 GB. The announcement politely reminds everyone to use Wi-Fi, but even the most patient router might file a complaint.

Now, a seasoned Proxy knows that voice packs can bloat these numbers even further, so plan your storage clear-outs accordingly. It’s a good time to ask whether 300 Polychromes is worth the emotional damage of deleting that game you haven't touched since last year. Spoiler: it probably is.

How to Pre-load Without Losing Your Mind

Each platform has its own ritual. The team has provided clear instructions, but where’s the fun without a little commentary?

PC

Fire up the HoYoPlay Launcher. A shiny "Pre-Download" icon will appear right next to the "Start Game" button, almost daring you to click it. The best part? You can keep blasting through Hollows while the files trickle in. Background downloading has never felt so heroic.

Mobile (Android and iOS)

Open the game and look to the bottom-right corner. There lies the "Pre-Download Resources" button. Tap it and walk away. Mobile users, however, are locked out of playing during the pre-load. The game essentially says, "You chose this, now suffer gracefully." Scheduling this overnight is the wisest move unless you enjoy staring at a progress bar.

PS5 or PS5 Pro

Here things get automatic. If your console has enough reserved storage, the pre-download will start on its own after a little idle time. It’s like a helpful ghost that only appears when you’re not looking. You can keep gaming while it does its thing.

Xbox Series X|S

Similar magic is at work. The automatic pre-download kicks in after launch if space permits. For the hands-on types, you can navigate to My games & apps > Manage > Updates and trigger it manually. Either way, playing during the download is still allowed. Multitasking at its finest.

The Maintenance Window and That Sweet 300 Polychrome Compensation

The real test of patience arrives on July 29 at 06:00 (UTC+8), when the servers go dark for an estimated five-hour maintenance. During this window, no Proxy can log in. It is the perfect time to touch grass, hydrate, or finally reply to those messages from three weeks ago.

When the update is complete, the mail carrier will deliver a crisp envelope containing 300 Polychromes. To be eligible, you must have reached Inter-Knot Lv. 4 before the maintenance starts. The compensation can be claimed until the end of Version 3.1, so don’t forget to check your mailbox. Three hundred shiny gems might just be the bait you need to pull that new Agent.

Post-Maintenance Update Procedures

Once the maintenance ends, updating the game itself is a short final step.

Platform	How to Update
PC	Exit the game, restart the launcher, and let it work its magic.
Android	Follow the in-game pop-up that will gracefully guide you.
iOS	Head to the App Store and tap Update. The classic blue button of destiny.
PS5 / Pro	Highlight the game on the home screen, hold the Options button, and select Check for Updates.
Xbox Series	Go to My games & apps > Manage > Updates, find Zenless Zone Zero, and confirm the update.

Why 3.1 Matters

While this announcement mostly focuses on the logistics of file delivery, the dev team promises new gameplay, optimizations, bug fixes, and the usual sprinkling of mystery that keeps Proxies glued to their screens. The full patch notes will drop separately, but for now, the important thing is getting your device ready. With sizes that rival some full-fledged AAA releases, Zenless Zone Zero continues to expand its stylish universe, one terabyte-shattering update at a time.

So, clear your storage, hug your Wi-Fi router, and set those alarms. New Eridu isn’t going to explore itself, and those 300 Polychromes have your name written all over them. Stay safe out there, Proxies, and may your download speeds be ever in your favor.
