I DID NOT MAKE THIS EXPLOIT! I've tried to do this before but this time will be a little different. All credits to creamapi and whoever helped make this. All right, so this exploit replaces one of your steam API files with a modified one that allows you to essentially tell the Arma 3 client that you own all the DLC already, regardless of what you actually paid.
