Once you have opened the map, on the left side of the program window you will see the words Header, Tags, Strings, and Scripts. Once you have opened Assembly, on the left side of the window you will see 'Open Content File' click that and find cex_beaver_creek.map you placed on your desktop and open it.
For the purposes of this tutorial we are going to find 'cex_beaver_creek.map' inside this folder, right click and copy it and paste it to the desktop.Īt this time i would advise you to create a folder inside this map folder called Backup, and copy all the maps inside the maps folder and place them inside the Backup folder for safe keeping. This folder contains all of Halo Reach's Maps. Inside the folder we just opened will be a bunch of files and folder, you want to find and enter the folder called haloreach, and then inside that folder, enter the maps folder. You want to click Local Files, Then Browse Local Files. Then click Properties, this will bring up a window and inside this window will be a set of tabs Head into steam, click library, and find Halo: The Master Chief Collection and Right Click it. Once you have Assembly we can get started. You Will also need to compile it, and there is a great video for that right Here
So first things first we are going to be using assembly, if you do not have Assembly, you may need to head Here and download the latest Dev version of Assembly.
