Install Custom Gametypes / Forge Maps Onto MCC Flight 3

HOW TO PLAY CUSTOM GAMETYPES AND CUSTOM MAPS ON MCC INSIDER FLIGHT 3:

STEAM USERS:

If you want the maps / game-types to appear as "built-in" variants:

1.) Place the game-types in your "MCC\haloreach\game_variants" directory
2.) Place the map variants in your "MCC\haloreach\map_variants" directory

WINDOWS STORE & STEAM USERS:

If you want the maps / game-types to appear as custom variants:

Navigate to "C:\Users\(USERNAME)\AppData\LocalLow\MCC\LocalFiles\(XUID)\HaloReach"

Place the game-types in the "GameType" folder.
Place the map variants in the "Map" folder.

NOTES:

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.) First, you must find your Xbox User ID (XUID):
    a. Navigate to "C:\Users\(USERNAME)\AppData\LocalLow\MCC\Temporary
    b. Open the "campaigncarnagereport1_1186_0_0.xml" (this requires that you have started / completed at least ONE campaign mission.)
	   With a program like Notepad++
    c. Once you have the file open, find the <player> header and look for the line that says "<Player mXboxUserId=0x000900000XXXXXXX"
    d. 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 "HaloReach"
5.) Open the "HaloReach" folder and paste in the "GameType" and "Map" folders.

Success! Now you have custom game-types and maps to play online during MCC Insider Flight 3!
