Quick Start

Using Collapse
Manage games, run repairs, update caches, and customize your experience.

Build plugins to add support for games beyond the four official titles.
What Collapse can do
Multi-game & multi-region
Launch Honkai Impact 3rd, Genshin Impact, Honkai: Star Rail, and Zenless Zone Zero — from Global, Europe, Asia, SEA, or Bilibili CN — all within one launcher.
Fast differential downloads
The Sophon engine downloads only changed file chunks, and HDiffPatch delivers tiny delta patches for Honkai Impact 3rd updates.
Game file repair
Full integrity verification and automatic repair for every supported game. Fix missing or corrupted files without reinstalling.
In-launcher game settings
Edit graphics, resolution, and audio settings for any game directly in Collapse — no need to launch the game first.
Cache management
Pre-download game settings caches before patch day so the game starts instantly after an update.
Plugin system
Extend Collapse with community-built plugins that add support for any game outside the official four titles.
