1) Extract all the .torrent files somewhere. 2) Use your preferred Torrent client. Download the actual torrent content of all the files in a single folder. ex: C:\SteamLibrary\steamapps\common\Arma 3\Global Conflicts Mod 2.1) This folder CAN be the same folder as the one created by our custom launcher, if you ever used it. Your torrent client will verify the already existing files normally. 3) Put the launch_script.ps1 on the same folder where your downloaded the mods with your torrent client. 4) Make a shortcut of "Open GC Arma" and use the GC loco icon if you want to make it pretty :) 5) Just double click shortcut to open the game.
