📋 About This Mod

Turns all allies in the campaign invincible for their respecting levels. Meaning elites will killable when playing as the humans but will be invincible when playing as The Arbiter

There is any older version posted by RazePhalanx here but its hasn't been updated since 2023 and he hasn't been active since Oct 2025. Though I will take this mod down if here ever returns and updates his original version.

All of the friendlies throughout the campaign have been made unkillable by any and all damage. Tags have also properly been assigned in respective missions, so while you are playing as the Master Chief; Marines and ODST will be unkillable, then when you are the Arbiter, friendly Elites, Grunts, Jackals, Hunters, and some Brutes will be unkillable. Heretics and flood should have no issues being invincible. Allies should also be unable to be infected by Flood Spores while they are still alive, though pre-set corpses and heretics can and will be infected.

How to install

-Backup your original map files (not required but recommended. Saves downloading times when reverting)

-Extract my file using 7zip

-Simply copy-paste these files to where yours are (mine would be: R:\SteamLibrary\steamapps\common\Halo The Master Chief Collection\halo2\h2_maps_win64_dx11)

-Run MCC with mods enabled and then hit play.

My other versions:

-Halo Reach: here

-Halo CE: here

-Halo 3 ODST: here

-Halo 3: here

-Halo 4: here

Troubleshooting

Step 1: Check your MCC version

-If a MCC update was released after the most recent mod version then wait a bit and I'll update the mod to the latest version

Step 2: Load up a different mission

-Due to the way the MCC stores saves, clicking resume or loading up the same mission may cause crashing or the changes to not apply

Step 3: Validate your files then redownload the mod

-You can do this by: right-click on the MCC, choose properties, then local files, and then click "validate local files" this will scan for any corrupt or changed files and restore them to their default setting

Step 4: Uninstall and Reinstall the MCC

-If it comes down to it, simply try reinstalling the entire game to make sure everything is back to square 1 safely

Step 5: Abandon Hope all Ye Who Enter Here

-Post in the bugs section or comments what's going on and I'll take a look when I get time to. I do check for new comments at least twice a week,
