As a dedicated Proxy, I always try to minimize downtime whenever a major Zenless Zone Zero patch arrives. Version 2.7 is almost here, and the development team has just opened pre-downloads for all supported platforms. I have already started pulling down the files on my PC and PlayStation 5, and I want to share a complete rundown so you can do the same before the scheduled maintenance begins.
The pre-download window runs from 2026/03/22 12:00 (UTC+8) to 2026/03/24 05:50 (UTC+8). By grabbing part of the files in advance, you should be able to enter New Eridu much faster once the update maintenance ends. That is a big quality-of-life win for anyone who hates waiting.
Pre-Download Window and File Sizes
The download size depends on your platform. Based on the official notice, PC players need about 4 GB, while mobile users on Android and iOS require roughly 3 GB. PlayStation 5 and PS5 Pro owners face a larger 13 GB package, and Xbox Series X or S players have the biggest pre-download at around 17 GB.
| Platform | Pre-Download Size | Can You Play During Pre-Download? |
|---|---|---|
| PC | ~4 GB | Yes |
| Mobile (Android/iOS) | ~3 GB | No |
| PS5 / PS5 Pro | ~13 GB | Yes |
| Xbox Series X/S | ~17 GB | Yes |
I appreciate that the official post also reminds us about storage space. These files are not small, and installed Voice Packs can change the total space required. A Wi-Fi connection is highly recommended unless you have an unlimited data plan or a very generous mobile hotspot.
How to Start the Pre-Download
Each platform has its own flow, so here is what I found while setting up my own downloads.
-
PC: Open the HoYoPlay Launcher and look for the Pre-Download icon next to the Start Game button. Click it to begin. PC players can continue playing during the pre-download.
-
Mobile (Android and iOS): Open the game and tap the Pre-Download Resources icon in the bottom-right corner of the screen. Mobile users cannot play during the pre-download, so I suggest planning your download for a time when you do not need to log in.
-
PS5 / PS5 Pro: Launch Zenless Zone Zero and, if the console has enough reserved storage space, it will automatically begin the pre-download after a short period. You can keep playing while this happens.
-
Xbox Series X/S: Similar to PlayStation, launching the game can trigger an automatic pre-download if there is enough reserved storage. You can also open the system home screen, go to My games & apps, select Manage, and check the Updates page. Xbox players can continue playing during the download.
Pre-Download Tips and Warnings
Before you start, I recommend checking your available storage. The official notice specifically says that due to the large size of the download, you should ensure you have enough free space and use Wi-Fi. Additionally, the Voice Packs installed on your client will affect the space required, so if you have multiple voiceovers downloaded, expect the package to need a bit more room.
For mobile players, the no-play rule during pre-download is the most important caveat. If you forget and start the download before a planned session, you may be locked out until the files finish. I always start mobile pre-downloads when I am about to sleep or work.
Version Update Maintenance and Compensation
The actual version update maintenance is scheduled for 2026/03/24 06:00 (UTC+8). The team estimates the maintenance will take about five hours, during which the game servers will be offline. I set a reminder every patch because once maintenance begins, you cannot log in until it wraps up.
Eligible Proxies will receive 300 Polychrome as server update compensation. To qualify, you need to have reached Inter-Knot Lv. 4 before 2026/03/24 06:00 (UTC+8). The compensation will be sent through in-game mail after the update is completed, and you must claim it before the end of Version 2.7. Do not forget this deadline, because unclaimed Polychrome is a wasted opportunity for future Signal Searches.
Updating After Maintenance
Once the maintenance window ends, the actual update process depends on your platform. On PC, exit the game, restart the launcher, and select update. On Android, enter the game and follow the in-game pop-up instructions to complete the update. On iOS, go to the App Store and select update. For PS5 or PS5 Pro, highlight Zenless Zone Zero on the home screen, hold down the Options button on your controller, and choose Check for Updates. On Xbox Series X/S, open the dashboard, go to My games & apps, select Manage, find Zenless Zone Zero on the Updates page, and confirm the update.
Final Thoughts
Pre-downloading is one of the easiest ways to get back into New Eridu as quickly as possible. I have already cleared enough space on my drives, connected to Wi-Fi, and set my console to download overnight. With Version 2.7 arriving soon and 300 Polychrome waiting for eligible players, this pre-load window is definitely worth using. Plan ahead, claim your compensation, and I will see you in the Hollows after maintenance.
Data referenced from SteamDB helps contextualize why a Version 2.7 pre-download is such a practical time-saver: large patch payloads and peak concurrency around update windows can amplify wait times if everyone starts downloading at once. Planning ahead—clearing storage for optional voice packs and initiating the preload during off-hours—reduces the chance of bottlenecks when servers come back after the 2026/03/24 06:00 (UTC+8) maintenance, letting you jump into New Eridu faster and focus on claiming the 300 Polychrome compensation before the Version 2.7 deadline.
