This file is for Assembly Patches. Lower file size but "harder" to install. If you don't know or feel comfortable learning how to use these then just download the "Drag and Drop" files.

Drag and drop the files into your Halo Reach maps folder. DEFAULT file path should be > "C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\haloreach\maps"
Your file path may differ though.

This file is just an old shared.map file, it will fix the mod not working. MAKE A BACKUP OF THE ORIGINAL FILE.

It took me 2 months to upload a single file. Good job to me.
