What's Delta Patch Update Feature?

The Delta Patch Update feature is an update function that Collapse uses which doesn't require you to re-download the entire game (with the benefit of having a reduced download size). This feature will only update the differences between files (hence the "Delta" name) from previous to the next version and produces the new patched files which will be used for the updating the upcoming version.

This feature was first introduced to Collapse Launcher in 1.0.22.3-RC1-Preview and does not exist the default launcher.

This feature is only available for Honkai Impact 3rd, for the following regions:

  • Southeast Asia
  • Global
  • Mainland China

How-To

1. Download the .patch (Recipe) file

Collapse no longer downloads the Recipe file automatically due to their size. You have to download the "Recipe" file to be used for the update. You can find them here. After the link opened, choose the folder of version number you want to update.

For example, if you want to upgrade to version 5.7, then go to 5.6.0-5.7.0 folder, etc.

You will find a few recipe files to choose from. Select the region you want to update to, then click on the "..." icon at the right side of the file and select Download to download the file to your machine.

Note: The following region codes are used to identify regions which are compatible with the Delta Patch update format

  • Hi3SEA -> Southeast Asia
  • Hi3Global -> Global
  • Hi3CN -> Mainland China

2. Move the .patch (Recipe) file to Game Folder

Once the download has finished, move the .patch file to the game folder.

To find out where your game is installed, open Collapse, select the correct game & region, and click on the Game Settings button and find the Open Game Folder button to open the game folder.

3. Start the Update

Once you have successfully moved the file to your game directory, Collapse will automatically detect click on the Delta Patch file. If it does not, please restart the launcher before attempting the update operation.

Once the file has been detected, click on the Update Game button and click Yes at the dialog. While the process is running, please DO NOT CLOSE the launcher and Do not Panic if the progress bar does not move or the program becomes unresponsive.

There is a high chance of your game files being corrupted if you interrupt this process. You cannot downgrade to a previous version once you update your game. However, you can convert back to your previous version by downloading the correct recipe file. Collapse is not responsible for game data corruption. Update time varies depending on system configuration.
