From the rules: Start at 8:22 (minutes: seconds) if you are using the intro mission cutscene skip mod.
Instructions: You have to be on PC obviously to use it. Download the patch3.dat and patch3.fat. Move them over to the game folder: Watch_Dogs2/data_win64 and you should be able to skip the cutscenes in the intro mission by pressing the button.
How does it not have it? It's the folder with the common.dat/common.fat/patch.dat/patch.fat files
I don't think that is the game folder. Those are not the game files. I have the game on Steam, and it's in Program Files (x86)\steam\steamapps\common\Watch_Dogs2. You would probably have the game folder somewhere in Program Files or something like that (depending on where you installed the game). The folder in Documents\My Games does not contain the game files that I'm talking about.
I got it on epic games so maybe that changes it, although it probably wouldn't
The WD2 game folder is not Epic Games\Watchdogs2. It's probably in Ubisoft\Ubisoft Game Launcher\games\Watchdogs2 because the actual game files are downloaded from Uplay.
