How to Install Halo Mods

Common Place to Get Halo Mods - https://www.nexusmods.com/halothemasterchiefcollection

1. Download a Mod File
2. Use WinRAR or 7Zip to Extract the .zip file, It should contain a .map file (and SFX, and SFX.info, if they have them)
3. Locate your MCC Directory (Steam\steamapps\common\Halo The Master Chief Collection)
4. Click on the Game that the mod is for (HR, H3, H4, etc)
5. Back up the files that the mods uses. (For example if the mod replaces shrine.map, backup the original shrine by renaming it, shrine_og)
6. Drag your Modded .map File in the Maps Folder, (and your SFX.fsb, SFX.fsbinfo files, in fmod/pc)
7. Launch MCC through Steam with Anti-Cheat Disabled

If your not sure which map it is, check the readme, and if it doesnt tell you this is a list of the map names and how they correspond to MCC
