## What it is
Collapse is an advanced open-source game launcher for miHoYo/HoYoverse games (Honkai Impact 3rd, Genshin Impact, Honkai: Star Rail, Zenless Zone Zero), built with C# and WinUI 3. It adds features beyond the official launcher such as game file repair, delta-patch updates, multi-region management, and in-launcher game settings editing.

## Use cases
- launch genshin impact without the official launcher
- repair corrupted honkai star rail game files
- download smaller delta patch updates for honkai impact 3rd
- manage multiple regions of a hoyoverse game in one place
- change genshin graphics settings without opening the game
- preload game updates before release
- convert game region from SEA to global

## When to choose
- you play miHoYo/HoYoverse games on Windows and want faster, smaller updates via delta patches
- you need to validate and repair game files or caches outside the game
- you manage multiple game regions or want to migrate from the official launcher
- you want an open-source, code-signed alternative launcher with plugin support

## When to avoid
- you play on macOS, Linux, or mobile - it is Windows 10/11 only and requires admin rights
- you only need a minimal launcher and are happy with the official one
- you want to modify or hook the game process - Collapse deliberately avoids that
