About this mod

A full, modded Campaign featuring tweaks to weapons, vehicles, AI, scenarios, and encounters to make the game as close to perfect as possible, while still being faithful to the OG experience.

Welcome to Ruby's Rebalanced Combat Evolved!


This is a full Campaign mod all about making an already fantastic game, as close to perfect as possible through tweaks to the sandbox such that every weapon and vehicle is viable and useful, with changes to AI and additions to encounters to make them more fun and interesting.

Changes include things such as increasing the Assault Rifle's accuracy, making Marines more competent as well as increasing their numbers, increasing the Warthog's acceleration, increasing the Scorpion's accuracy, giving the weapon sandbox more use against Hunters and Flood, and so much 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\halo1\original\build\maps, everything from a10 to d40.

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. Have fun!


Follow the same installation instructions, but place the extracted file into C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection, and overwrite the existing folder.


Halo CE, being the first Halo game, was not only pivotal as a game, but to this day, I think still has the best sandbox out of any Halo game, making the game a treat to play. And it's been a joy to hopefully make it even better, such that the game is as close to perfect as possible. We're just getting started.
