Welcome to Ruby's Rebalanced Combat Evolved!


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.

Additionally featuring quality of life improvements to the general gameplay or immersion.

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, even adding back in the cut Flamethrower, and so much more.

For a full list of changes, see here.

THIS MOD IS ALSO AVAILABLE FOR CUSTOM EDITION, RECOMMENDED VERSION (but it does not currently work with MCC). The Custom Edition version includes all the improvements made by CE Refined, restoring and fixing the graphics to resemble the original Xbox version. >>>>> DOWNLOAD

certain changes will only appear on the old visuals, such as Ultra Elite colors, Flood shield flares, and the Flamethrower.

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. Also backup c20.s3dpak and d20.s3dpak, which are found in C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\halo1\prebuild\paks.

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

3. Extract both .s3dpak files from the same archive into the place the old files of the same name used to be. These are required for the Flamethrower to not crash the game. This does not apply to the Custom Edition version.

4. 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.
