How To Play Local, Split-Screen Multiplayer (VS. and COOP)

1.) If you are using a PS4 or PS5 controller, you have to use the DS4Windows Program.[github.com] In order to set that up, go to the settings tab in DS4Windows, “Controller/Driver Setup”, click “Install ViGEmBus Driver”, then restart your computer.

2.) Download the latest Nucleus Coop Program[github.com] to play split-screen. (OPTIONAL: Use the 7zip[www.7-zip.org] program to extract, if needed.)

3.) Extract and place the NucleusCoop folder you downloaded anywhere. (I placed mine on my desktop.)

4.) Place the NucleusCoop folder into the root of your hard drive.

5.) Make sure Halo the Master Chief collection is located on the same hard drive as the “Nucleus Coop” folder (in this example, it is C:/). If not, put them on the same hard drive. But do not put the “Nucleus Coop” folder into your Master Chief collection directory.

6.) This step is optional. Right click on the program, “NucleusCoop.exe”, go to properties, go to the “compatibility” section at the top, check the box marked “Run this program as an administrator”. Press “OK”.

1.) Do the prerequisites.

2.) Start “NucleusCoop.exe”.

3.) Click on the “Download Game Scripts” button in the bottom left.

4.) Search for Halo. Find Halo the Master Chief Collection. Click on it, then click “Download”.

5.) It will finish, then pop up with a dialogue. Click yes, then find your Halo executable located in “your game directory”/MCC/Binaries/Win64/MCC-Win64-Shipping.exe. (You can find “your game directory” by right clicking on the game, then going to manage, then click on browse local files.)

6.) Set up your controllers by clicking on the small box below the keyboard icon. Drag your controllers into your set up configuration. If you have a multi-monitor setup, you can also setup each screen for split-screen here!

7.) Hit the right arrow button in the top right, below “Mod version”, then the “Play” button.

8.) Lastly, to connect the instances, go to the Settings, in the Network tab swap from Xbox Live to LAN on all instances, save the changes and go back to the menu, open the roster by pressing X or hovering over it and join with each instance to Player 1’s lobby.

9.) (OPTIONAL STEP: This will reduce startup time) Exit the Nucleus Coop application. Inside the “Nucleus Coop” folder, go into “scripts”, right click on “Halo The Master Chief Collection”, click “edit”, do ctrl+F, find 35, change 30 to 3, and save and exit. Reopen the Nucleus Coop application.

10.) (OPTIONAL STEP: To further reduce startup time) Download the skip intro mod[www.nexusmods.com], and place it in Halo The Master Chief CollectionMCCContentMovies, and replace the old file.

“Could not find a part of the path ‘f….commonhalo the master chief collectionhalo1originalbuildshaders’. “.

1. Go to your “Nucleus Coop” folder, then the scripts folder inside that folder,
2. Right click on the “Halo the Master Chief Collection” Javascript file
3. Click open with “Notepad”.
4. Edit the “Game.DirSymlinkCopyInstead” line to “Game.DirSymlinkCopyInstead = [“halo2\prebuild\shaders_2_cache\prebuild”];”
5. Save and exit.

“Halo fatal error” or “Halo error static”.

• Verify the integrity of the game
• And delete and reinstall Nucleus Coop
  1. First, delete the old script completely by:
  2. right clicking “Halo: The Master Chief Collection” in the Nucleus Coop app, then clicking “Remove game from list”.
  3. Then, go to the “Nucleus Coop” folder, within the “Content” folder, delete the “Halo MCC” folder, if it is not already deleted.
  4. Then, go to “Nucleus Coop””Scripts” and delete “Halo The Master Chief Collection.js”, if it is not already deleted.
  5. Right click on your game within Steam. Click on “Properties”, then the “Local Files” tab, then “Verify Integrity of Game Files”. A dialogue will pop up, click yes.
  6. Finally, download the “Halo: The Master Chief Collection” script in the Nucleus Coop app again. The bug was fixed on 05/22/2020.

First, verify the integrity of your game file. Make sure your game is on the same hard drive as your Nucleus Coop folder. If those two things didn’t work, try moving your game to your C: hard drive.

“Could not find a part of the path…’shaders_2_cacheprebuild’.”

1. Open Nucleus and select MCC on the left side. Click game options at the top and press open game script. Search this file for Game.DirSymlinkCopyInstead.
2. Written here you should have one of 2 options. The correct DLC must be installed depending on which option you have or it’ll crash. Make sure its written exactly as shown without any typos. if it says: Game.DirSymlinkCopyInstead = [“halo1\original\build\shaders”]; Install the Halo CE Campaign
3. If it says: Game.DirSymlinkCopyInstead = [“halo2\prebuild\shaders_2_cache\prebuild”]; Install the Halo 2 Campaign
4. If these campaigns are already installed, verify your game files.

“Missing Content” error.

1) Download the latest version of the Halo the Master Chief Collection script.

2) Then If you are still experiencing the missing content with this latest version, set these lines to false in the script:
Game.UseNucleusEnvironment =
Game.GoldbergNoLocalSave =

“Error encountered while signing into Xbox Live”

Reinstall the script by deleting the Halo script and redownloading it. And verify the integrity of your game.

When using the mouse and keyboard window it blocks you from walking.

Mouse and keyboard is not supported by the mod.

One controller controls multiple people or one controller does not function properly.

Reinstall the latest script and verify the integrity of your game. Also, exit Steam, and play without Steam.

Put the “Nucleus Coop” folder you created into a different location, such as C:/Program Files (x86). Also disable the “Show Status Window” in Nucleus Settings. This is a new feature introduced in the last version but is causing issues for some users.

Pop window that says “ERROR: Exception in ResetWindows for…”.

Go to the “Halo The Master Chief Collection” script, and increase the pause time from 3 to 4, 5, 6, etc. Also disable the “Show Status Window” in Nucleus Settings. This is a new feature introduced in the last version but is causing issues for some users.
