About this mod

A full, modded Campaign that tweaks the sandbox to make a more gratifying and decision-based game, where every piece of that sandbox has a distinct role. As well as adjusting Legendary difficulty to be less frustrating, but more fair while still challenging.

Permissions and credits
The mod will be rebuilt and updated after Halo 2 Rebalanced is updated.

Welcome to Ruby's Rebalanced Halo 3!


This is a full Campaign mod focused on refining the sandbox to create a more gratifying and decision-based game. The entire sandbox has been tweaked such that every weapon, vehicle, and AI has a distinct and useful role to fulfill, all about finding the best tools depending on the enemies, situation, and environment.

Legendary difficulty has been refined to be less frustrating, and more fair, while still challenging. Also featured are several level changes and additions, cosmetic tweaks, and more!

For a full list of changes, see here.

Below is an in-depth video covering key changes.


1. Move all of your vanilla maps to a backup location. Maps are found in C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\halo3\maps. Back up your vanilla map files, everything form 010_jungle.map, to 120_halo.map, as well as campaign.map, and shared.map.

2. Use a program like WinRAR or 7zip to extract the modded map files, and place them into where the vanilla maps used to be.

3. Whenever you want to play the modded maps, just make sure you open the game with anti-cheat disabled. Any time you want to play non-Campaign Multiplayer while the mod is installed, you must also place back in the shared.map file. Have fun!


Special thanks to Vengeful Vadam, and the HaloMods and Halo 2 Overhaul Discord servers for their help and inspiration in making this mod.

Halo 3 is fondly remembered as the pinnacle of the series, and I'd have to agree. So it's my pleasure to give it even more love, and allow us to finish the fight once again!
