About

Halo Party is a site for finding Halo Master Chief Collection custom game modes and maps.

Instructions

After you download maps & game types, you need to place them in the game’s directory. After you do they will be automatically loaded during game launch (you need to relaunch the game to see new content).

In these instructions I use a few variables in file paths that you’ll have to replace with whatever applies to your situation.

  • <USERNAME> is your Windows username.
  • <HALOGAME> with the version of Halo you’re using. Halo3 or HaloReach
  • <XUID> is your unique Xbox user ID (not gamertag). See below to find what it is.

Install Location

Navigate to C:\Users\<USERNAME>\AppData\LocalLow\MCC\LocalFiles\<XUID>\<HALOGAME>

Place the game type files (.bin) in the GameType folder. Place the map variant files (.mvar) in the Map folder.

If you navigate to C:\Users\<USERNAME>\AppData\LocalLow\MCC and realize that you DO NOT HAVE a LocalFiles directory, do the following steps:

  1. Find your Xbox User ID (XUID):

    1. Navigate to C:\Users\<USERNAME>\AppData\LocalLow\MCC\Temporary

    2. Open the campaigncarnagereport1_1186_0_0.xml (this requires that you have started / completed at least ONE campaign mission) with a text editor like Notepad.

    3. Once you have the file open, find the <player> header and look for the line that says <Player mXboxUserId=0x000900000XXXXXXX

    4. That number is your XUID.

  2. Navigate back to C:\Users\<USERNAME>\AppData\LocalLow\MCC and create a new folder called LocalFiles.

  3. Open LocalFiles and create a new folder named with your XUID number MINUS the 0x at the front. It should look something like this: 000900000XXXXXXX

  4. Open your 000900000XXXXXXX folder and create a new folder called <HALOGAME>

  5. Open the <HALOGAME> folder and make new GameType and Map folders. Move your downloaded game types (.bin files) and maps (.mvar files) into them respectively.

Relaunch the Master Chief Collection and enjoy your new content! Halo Party lists the base map and game types for everything to help you find content quickly, so feel free to reference back to it.
