Lord of Mysteries Pre-Download Is Live: Client Sizes and Platform Status

What Was Announced

Spark Nexa opened China pre-download for Lord of Mysteries on August 19, 2026 at 08:00 CST (00:00 UTC / 20:00 ET and 17:00 PT on August 18), announced through the official TapTap channel. Character pre-creation opened the same day at 12:00 CST (04:00 UTC / 00:00 ET / 21:00 PT on August 18). The official post gives a start time but no closing time; Chinese media reports the window closes at 22:00 CST on August 20, which the official post does not state. Verified at 17:35 CST on August 19.

Platform status at the time of writing:

• PC — open. The publisher distributes a launcher, GMZZLauncher v1.1.43.0.
• Android — open. An APK is distributed directly by the publisher's CDN, version 1.1.1.
• iOS — open through the App Store China listing.

The three client figures are different things and should not be confused:

The PC file is a launcher, not the game. The full client downloads after you run it. Chinese media coverage also reports roughly 30 GB of additional data on first launch; that figure is reported rather than stated in the official post.

Open Beta begins August 21. The official opening hour has not been confirmed.

What It Actually Means

The storage requirement moved, and the direction matters. Our system requirements page carried 80 GB, taken from the official Gray Fog Test FAQ in June. The current official TapTap listing asks for 90 GB. That is a 10 GB increase between a limited wipe test and the Open Beta build — consistent with a launch client that ships more content than the June test, which opened at 12:00 on June 26 and has since ended. We have updated the page to 90 GB and kept the June figure visible as history.

Pre-creation is a name-claiming window, and Western players routinely miss it. In Chinese MMO launches, the pre-creation period that opens before launch day is when character names get taken — the desirable ones are typically gone within the first hours. It is not an early-access period: you create the character, then wait for the servers to open on August 21. The official post announced only when the window opens, not when it closes — so if your name matters to you, the safe assumption is that it can close at any point before launch. Publishing a start time without an end time is normal practice on Chinese launches, where the window usually runs until the pre-launch maintenance window, and that gap is exactly where the unofficial deadlines circulating in Chinese media come from.

"Downloadable" is not the same as "playable" for overseas players. The PC and Android URLs are publisher-distribution CDN links, not region-locked store pages, and we tested both directly from outside mainland China on August 19: each one starts downloading normally. That settles the download step and only the download step. Account registration for Chinese servers generally involves China-side phone and real-name verification, and we have not independently confirmed what this specific title requires; our overseas access guide covers what is known so far. Connection quality is a separate question again, and booster support for this title is not confirmed before launch.

The 149 MB figure will mislead people, and it is worth being explicit about. A player who sees "149 MB" and clears 1 GB of disk space will fail at the second step, not the first. The number that determines whether you can install the game is 90 GB, not 149 MB.

What You Should Do

1. Clear 90 GB on PC before August 21 — that is the official listing's free-space figure, not the launcher size. See our system requirements page for the full spec.
2. If you want a specific character name, pre-create as early as you can. Media reports put the closing time at 22:00 CST on August 20 (10:00 ET / 07:00 PT), but the official post does not confirm an end time — so do not plan around that deadline. Creating the character does not let you play early; servers still open on August 21.
3. Android players: use only the official route linked from our download page. Do not install Lord of Mysteries APK files from third-party mirror sites — repackaged clients cannot be verified and may be modified. This matters more than usual right now, because the official Android route is a direct CDN file rather than a familiar app-store button, which is exactly the situation mirror sites exploit.
4. Android storage: budget well beyond the 1.93 GB download. Reports point to roughly 30 GB more on first launch.
5. Overseas players: read our overseas access guide before launch day rather than during it. Booster support for this title is not confirmed before launch, and we will not recommend one until we have verified it ourselves.

What's Still Unconfirmed

• The Open Beta opening hour on August 21. Media reports name a time; the official post does not. We are tracking the official TapTap channel and the WeChat account, and will update our release date page when an official hour appears.
• When the pre-creation window closes. The official post announced a 12:00 CST start on August 19 and no end time. The 22:00 CST August 20 figure circulating in Chinese media is not in the official post. Tracking the official TapTap channel; will update this article and our release date page.
• Exact account requirements for players outside mainland China — whether a China-side phone number and real-name verification are mandatory for this title. Tracking the official channels; will update /beta/how-to-play/.
• Whether first-wave redeem codes arrive with pre-download or at launch. Tracking the official WeChat account and launch stream; will update our codes tracker.
• Booster support. We will test GearUP and LagoFast against the live servers after launch and update /download/ only after that.
• Any global or regional release. No official statement to date. This pre-download is China Open Beta only.
