I know, it's not a good one. But at least we made it lol~ neon-nyan
Collapse was originally designed for Honkai Impact 3rd. However, as the project evolved, this launcher is now a game client for all currently released miHoYo Games.
This is an offline installer. There are separate installers for web and offline installation.
If you intend to redistribute either of these installers in the setup for your own product or application,
we recommend that you choose the web installer because it is smaller and typically downloads faster. You
can download the web installer here. Wherever possible, Microsoft recommends you use the Web Installer in
lieu of the Offline Package for optimal efficiency and bandwidth requirements. The offline package can be
used in situations where the web installer cannot be used due to lack of internet connectivity. This
package is larger than the web installer and does not include the language packs. You can download and
install the language packs from here.
NuGet is the package manager for .NET. It enables developers to create, share, and consume useful .NET libraries. NuGet client tools provide the ability to produce and consume these libraries as "packages".
Amazon Games app is a Windows PC game launcher that allows you to claim, download, and play new and classic Windows PC games every month from Prime Gaming.

Why "Collapse"?
Collapse came from the Honkai Impact translation in Chinese and Japanese. The word came from [崩坏] or Bēng huài in Chinese and also [崩壊] or Houkai in Japanese, both meaning "Collapse" which is why we chose it as our launcher name with the added inspiration that this was supposed to be an alternative (enhanced) launcher for Honkai Impact 3rd in the first place.
Collapse contains advanced features for Honkai Impact 3rd that not only provide you with the ability to download and launch the game, but also some additional features that the Official Launcher doesn't have, including:
Game Data Repair (with less bandwidth required than the Data Repair feature in-game).
Changing Game Settings (Graphics Settings & Audio Settings) without opening the game.
Multi-Region Game Download Support (Allows for downloading and launching different versions of the game).
Steam to Global version conversion (without re-downloading the whole game).
Global to SEA version (or vice versa) conversion.
Multi-session Download for faster Game Download/Installation.
Multi-thread Game Extraction for faster installation.
Delta-Patch Update Mechanism for smaller updates (Click here for more info).
Ability to select Graphics API (DirectX 11 (FL: 10.1, 11.0 and 11.1) and DirectX 12 [May crash the game in newer stages]).
Not only that, this launcher also has some advanced features for Genshin Impact, including but not limited to:
Choosing your voice-line language during the first installation, so you don't have to download it inside the game.
Repair the game files including Game Caches, Cutscenes, Audio Pack & persistent files outside of the game.
