So, I've downloaded a modded MW3 survival mode gamesave, but where do I place it on my memory stick to put in my xbox?
You need to configure your usb with the xbox so it converts it to a 360 memory unit,then copy a mw3 save from your hdd to your usb.Then open ur usb in 360rev using usb explorer.Then just change the ids on the modded save to your ids and then inject the save into the same folder as the save you just copied over to the usb.
just remember mate for the mods to work continue campaign soon as game starts press start then save and quit then go to survival mode and you should have the mods
