1)Delete all your Custom game modes for MW3
2)Make a new one and disable Custom classes
3)Edit the Defualt classes and name them what you want but put 2 random characters in front of them for ex. I want it to say Coke i would put: "AACoke"
4)For the class items put whatever you want but remember what you put (I write it down on paper)
5)Transfer your Custom Game mode on to a USB

1) Make two folders one titled 'Original' the other titled 'Extracted'
2) Open Horizon's device explorer, drag your custom game mode into the folder titled original
3) Open up your custom game in horizon and click "Contents" you will see the CMR data and right click, extract to the 'extracted' folder
4) Open up HxD and drag in the 'extracted' folders CMR data you will see your class names on the right side of the coding if not just CTRL F and search for your class names and include the "AA" you put in before all of your class name's
5)click in front of the "AA" and put your color code ex. "^1" (I will lis the color codes later in the post)
6)Do this for all of your class names as desired
7)now your weapon values for your class will be listed above not before your class name's and say I have the m4 I will look in the Hex offset's for '09' (the m4's Hex value) (I will have the weapon values listed in the post aswel
8) *Highlight all the codes except for the fist four byte's, click Analysis>Check sum>CRC-32>Enter in your new check sum in place of the first four byte's
9)Save it in HxD then you can open up Horizon again
10) Open your Original save! not the 'extracted'
11) View contents right click your 'CMR' data and Replace with the CMR data it shows click the first one (Make sure you don't click the .BAK file as that's your Backup!)
12)Rehash and Resign then save to device

1) load up MW3 go to Xbox live>Private match>Mode>My Mode's
2) Select your USB with your Modded Custom game on it!
3) Start the match and you should have the class mod's if you did it right!
