How to preload — by platform

PC (Epic, official launcher)

  1. Open the Wuthering Waves launcher
  2. If a "Preload" or "Pre-install" button appears next to the play button, click it
  3. If you don't see one, click the gear / settings icon → check for an update queue
  4. Confirm at least 32 GB free on the install drive before starting the download
  5. Download size will read ~17 GB but reserve 32 GB so unpack doesn't fail mid-install
  6. Once download completes, do not click "Install" until 06-08 11:00 UTC+8 — installation happens automatically when maintenance ends

Mobile (iOS / Android)

  1. Open the Wuthering Waves app
  2. Go to settings → game settings → "Resource preload" (sometimes labelled "Pre-download")
  3. Tap "Download"; the patch resources will queue in the background
  4. Use Wi-Fi — mobile data could burn 10+ GB
  5. Keep the app open in the foreground for the first 30 seconds to seed the queue, then it can run in background

PlayStation

  1. From the WuWa game card → press Options → Check for update
  2. Once Sony's server receives the patch, preload appears in the system download queue automatically
  3. Sony pushes preloads region-by-region — your queue may not open until a few hours after PC preload starts
  4. Reserve ~32 GB on your console SSD
Plan Lucy / Rebecca / Lucilla ascension materials while you wait for the download with the Material Planner.

Common mistakes — don't waste your preload

  • Skipping the 32 GB free-space check. Download is ~17 GB but install/unpack needs ~32 GB peak. If you only freed 18 GB, the install fails mid-process and you re-download.
  • Closing the launcher mid-preload. Most platforms support resume, but interrupting the unpack stage (which starts immediately after download) corrupts the patch. Leave the launcher open through download and verify.
  • Pre-installing manually before maintenance ends. If your launcher offers a "Install now" button after download, do not click it until 11:00 UTC+8 on 06-08. Manual installs sometimes patch incomplete versions.
  • Mixing CN and global preload. CN server preload and global server preload are separate downloads. Make sure your launcher region matches your account.
  • Mobile preload on cellular. 10–12 GB on cellular data plans can cost real money. Wait until you're on Wi-Fi.

Maintenance compensation

Kuro Games typically rewards ~300–600 Astrites + Premium Tuners + materials for patch maintenance, scaled to actual downtime. These arrive in your in-game mailbox automatically after you log in post-maintenance — no claim button required. If maintenance overruns the 11:00 UTC+8 estimate, expect additional compensation in a follow-up mail within 24 hours.

The 3.4 livestream codes (June codes) live in the Active Redeem Codes page. Expect a fresh batch from the next official social-media drop around launch day.

What to do during the 7-hour maintenance window

  1. Read the Lucy build guide — Phase 1 banner unlocks the moment maintenance ends
  2. Plan your Astrite budget with the Pull Calculator
  3. Read the free Rebecca event guide — claim her during Phase 1
  4. Skim Lucilla's preview in the Lucilla build guide if you're considering Phase 2
  5. Compare Spectral Trigger vs your current Pistol with the Weapon Compare tool

FAQ

Can I play 3.3 content while preloading 3.4?

Yes. Preload only stages the 3.4 files; the 3.3 client keeps running normally until maintenance starts at 04:00 UTC+8 on 06-08.

Will the actual download be smaller than 17 GB?

For most players yes — the launcher delta-patches against your existing 3.3 files, so the effective download is usually 8–14 GB. The "17 GB" figure is the maximum for someone reinstalling from scratch.

What if preload doesn't show up in my launcher?

Wait an hour and restart the launcher. Region rollout sometimes lags by a few hours. If 24+ hours pass and your client still shows no preload option, verify your launcher version is up to date.

Do I lose my characters / progress?

No. All character data, Resonators, Echoes, Astrites, mail, and inventory carry over. Maintenance is purely server-side updates plus client patching.

Is preload required, or can I download after maintenance?

Not required. You can wait until after 11:00 UTC+8 on 06-08 and download then. But preload means you skip ~30 minutes of queue at launch — recommended if your bandwidth is metered or you want to be on Lucy's banner in the first hour.

What is the Cyberpunk: Edgerunners collab and is it permanent?

3.4 is Wuthering Waves' first crossover with the Netflix anime Cyberpunk: Edgerunners. Lucy and Rebecca are collab characters. There has been no precedent for collab characters getting reruns in this game, which strongly suggests missing the Phase 1 banner means losing Lucy permanently. Plan your Astrite budget accordingly.
