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
