Patch notes outline the update and provide links to the full patch notes, with Wuthering Waves available on Steam, Epic Games Store, the official client, App Store, Google Play, PS5, and Steam Deck compatibility.

Gameplay improvements include performance fixes for PC and mobile, faster leveling, a streamlined material farming tracker, improved visuals, and expanded controller support.

New content arrives with Echoes of Sigillum and names like Nameless Explorer, Iceglint Dancer, and Kronablight, plus Tacet Discord Nest at Starblind Crashsite and new Sonata Effects—Trailblazing Star, Chromatic Foam, and Sound of True Name—with set bonuses affecting Fusion Burst, Tune Rupture, and Echo Skill interactions.

Version 3.1, titled For You Who Walk in Snow, is live on PC/Mac, mobile, and PS5, introducing pullable characters Aemeath and Luuk Herssen and granting access to their signature weapons.

A new region debuts: Roya Frostlands, specifically the Frostlands Surface, expanding into a vast icy zone with key locations such as Frostlands Transit Port, Mount Gjallar, Starblind Crashsite, Upphaf Forest Ruins, and Tidelost Forest.

Access details specify permanent availability of the main story content after Version 3.1, with the Afterstory remaining accessible permanently after February 26, 2026, and require completing designated earlier chapters to unlock new material.

The update introduces a main quest arc in the Roya Frostlands, where Aemeath accompanies the player to address a frequency loss and unlocks Exostrider lore, with a new post-story segment linking to Luuk Herssen and a Fractsidus tie‑in called All That Sunlight Touches, gated by completion of earlier chapters.
