About this mod

A two-level prototype for a soon-to-be full Campaign overhaul that has three goals: to give every piece of that sandbox a distinct role. To provide for a more immersive and hardcore experience as an ODST. And to expand upon the untapped potential of the original game.

Permissions and credits
Welcome to the ODST Rebalanced Prototype!


This is a two-level prototype for a soon-to-be full Campaign and Firefight 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.

  • Provide for a more immersive and hardcore experience; making the player feel much more like an ODST than a Spartan; vulnerable, but still deadly and capable. Stamina has been removed, and health packs are more spread out, but health has been buffed. Meaning smart planning, and usage of cover is key to defeating the waves of enemies and managing your health.

  • Expand on the untapped potential of the original game. Such as adjusting the levels to feature fully-functional enemy Elites, adding back in weapons from Halo 2, and other cosmetic changes that harken more toward Halo 2 than 3.

This prototype features Tayari Plaza and Uplift reserve, as well as fully-playable Firefight maps in Crater daytime, and Lost Platoon!

For a full list of changes, see here.


1. In the directory, C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\halo3odst\maps, backup the files "sc100.map", "sc110.map", "shared.map", and "campaign.map".

2. Extract the .map files of either the Tayari Plaza, or Uplift Reserve archives into the same folder. WARNING: do not have them both installed at the same time; since they are from different versions of MCC, the files are incompatible. Only have one installed at a time.

3. In the directory, C:\Program Files (x86)\Steam\steamapps\common\Halo The Master Chief Collection\halo3odst\fmod\pc, backup the files "english.fsb", and "sfx.fsb", then extract the mod's provided .fsb files, and place them where they used to be. The two .fsb files installed can be from either archive; they are compatible with both Tayari and Uplift.

4. 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 ODST Rebalanced until the modding community has some method of preserving mods from being broken from updates to MCC.
