Manual installation
Backing up the vanilla maps
First, locate your maps folder under "Steam\steamapps\common\Halo The Master Chief Collection\halo3\maps". Make a backup of all the campaign maps (starting with 005_intro and ending with 130_epilogue) so that you can always revert to the default maps.
Backing up the vanilla sound files
First, locate your maps folder under "steamapps\common\Halo The Master Chief Collection\halo3\fmod\pc". Make a backup of the "sfx.fsb" and "sfx.fsb.info".
Installing the mod
This last part is pretty simple, in your "Halo The Master Chief Collection" folder just drag the "halo3" folder from the mod into your game's folder and replace all of the files.
Intro
Alright so I know there are tons of campaign rebalances out on the nexus but I want this mod to be more than just a rebalance. This is only the campaign portion of what I want to achieve with this mod. Most of the changes and additions I've made to this mod will work as a base for everything I make in the future. So after I overhaul Halo 3's mp, odst's campaign, and firefight I want to make some custom levels and scenarios using the changes and additions I've made to my "Mythic Overhaul". I also plan on releasing a few tag packs of the stuff that I've made at some point in the future.
Breakdown of the mod's features
General ammo packs for the UNSC and Covenant can be found throughout the levels.
