You aren't the only one who finds this "War for Media Fame" rather crazy be assure of that On to your questions 1. Absolutely not the mod currently works by modifying a part of the Engine that was developed for patching the Game easier by Ubisoft this has no impact on the Save System directly. 2. Absolutely easy just kill in the Game directory patch.dat and patch.fat and vanilla shaders and level setup will be restored. This was Before the 1.03 patch though since the 1.03 patch you need first to save Ubisofts patch.dat/fat before you replace them with modded ones and later restore them to get the vanilla + ubisoft patch results. 3. Yes needs modification of the files inside patch.dat you have to unpack those and modify them to the values you would like the DOF to be see Alphaz Guide. What modders are mostly currently doing is changing the shaders and changing the Level Setup by hand that normally would be changed via the Watch_Dogs Editor in a GUI And what everyone tries to understand currently what hash values are which options, though not many or really actually currently no one really releases his results of his findings what value change what part Kadz as Alphaz was actually the first who gave a inside look into his findings After the problems he had with TheWorse his Ego of saying he invented everything on his own where he Kadz wasn't really sure about and saw more the Financial interests of TheWorse via donation pulling in front of TheWorse his goals. At least that's my understanding of this whole situation and many people around find this stupid or just have their own Visual ideas of where to bring this too and started doing it themselves but basing their mods on rather Kadz or TheWorse his findings which is absolutely ok and we should all share our knowledge and if you want to donate money to someone you shoul rather donate it to people like Rick who reverese Engineered Ubisoft data system and others who make this all possible to take a peek into the files @ all Most are keeping it secret and create Media Buz with their Result findings to get that 1 second of Fame Actually the Media Buz comes from People who actually understand rather nothing or less of what's going on but rather wan't to be first to make a article about it to higher their click rates and create Buz themselves it's a funny loop.
