Wuthering Waves 3.8 adds Lily and Train of Souls, swaps in a launcher on Steam

Wuthering Waves version 3.8, "Lilies in a Dying Dream", went live on November 12 after a maintenance window that the official patch notes put at 04:00 to 11:00 (UTC+8). Alongside new story content, the update changes how the game installs on Steam: Kuro Games has replaced the Steam download with its own Official Launcher, and players have to reinstall.

What 3.8 adds

Kuro's Steam post from November 11 lists the 5-star Resonator Lily (Spectro, Pistols), available through the Bloom of Yesterday's Dreamsoil Featured Resonator Convene, plus the 5-star pistol Lullaby. The patch notes give her roles as Support and Healer, Traction and DMG Amplification. The story continues with Main Quest Chapter IV Act V, "A Bouquet for Tomorrow", which leads to the new area Train of Souls; the patch notes say the area stays permanently after the update.

The patch notes describe Blitz Mode as an option that can be switched on or off when claiming rewards in Simulation Challenge, Forgery Challenge and other challenges. Rover's Resonance Conversion now auto-switches the equipped Echo set, and the Guidebook's functions were optimized. On top come a new Tactical Hologram challenge, Calamity Effigy, several events such as the Combat Event Dreamfield Odyssey, and on some consoles PSSR support and a Graphics Quality tab. The patch notes also list a Bug Fixes Compensation of Astrite x300.

The launcher switch

Kuro first previewed the change on September 29 and repeated it in a Steam post on November 5. Players are told to completely uninstall the old game package and then install the Official Launcher via Steam. Account data and progress are not affected, Kuro says, but login failures, payment errors or missing map assets can mean the old package was not fully removed.

The stated reason is tiered resource downloads. The November 5 post speaks of three tiers (UHD, HD and SD) in future versions, while Gematsu describes a choice between Full Resources and Basic Resources in 3.8. Kuro's maintenance notice says the feature is still a limited test and that players outside it get the Full resource package. Pre-downloads through the launcher are promised once pre-download for Version 4.0 starts.

The Steam numbers moved in the same days. Reviews arrived at 403 per day over 42 hours, against 28 per day before, and the store page now shows Recent Reviews as Mixed, with 58% of 1,435 reviews in the last 30 days positive. The overall score stays Very Positive at 86% of 58,784 reviews. On November 12 the game ranked 55th in Steam's most played chart with a peak of 20,984 players, up from 79th a week earlier.

Much of the player feedback is about the launcher. In the Steam community, one player writes that the update effectively forced everyone to reinstall. A Steam reviewer who says they love the game adds, "I hate how they forced us to use a launcher", and a Linux player reports an invisible launcher that only worked after switching to Proton DW.

The game remains free to play on Steam. Anyone returning on PC should plan for a full reinstall and remove the old files first. Endgame players have until 2026-12-22 03:59 (UTC+8), when the current Endstate Matrix cycle, Adversity Vanguard, ends.
