About this mod

A two-level prototype for a soon-to-be full Campaign overhaul that has three goals: to give every piece of the sandbox a distinct role. To redesign the less enjoyable parts of the game. And to make the game feel much more at home with Bungie's games.

Welcome to the Halo 4 Rebalanced Prototype!


This is a two-level prototype for a soon-to-be full Campaign overhaul which has three goals:

  • Tweak the entire sandbox 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 for a more decision-based and gratifying game.

  • Redesign some of the less enjoyable parts of the game to be much more palatable, such as making enemy fire and tracking projectiles more manageable, overhauling the Prometheans' gameplay loop, and reimagining the Prometheans' weapons to be much more unique.
  • Make the game feel much more at home as a Halo game. In restoring various elements from the Bungie games such as weapon and vehicles attributes; their feedback and effects, AI abilities and ranks, and creative and dynamic encounter design.

This prototype features the missions Requiem and Forerunner.

For a full list of changes, see here.


1. In the directory, C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\halo4\maps, backup the files "m020.map", "m30_cryptum", "shared.map", and "campaign.map".

2. Extract the .map files of the same names from the mod archive into their place.

3. Whenever you want to play the modded maps, just make sure you open the game with anti-cheat disabled. Have fun!


As this is a Prototype, any feedback is welcome! Let me know if I achieved my three goals mentioned above. Things such as enemy or weapon placements may not reflect the final version. I will not be continuing with Halo 4 Rebalanced until the modding community has some method of preserving mods from being broken from updates to MCC.
