Although i was sure that i had not turned hardcoe off at any time in the game, i started a new one, again, making sure hardcoe was on at all times.
I followed the path of Caesar this time and got that ending, i even watched the credits this time to make sure that had nothing to do with it but again, no hardcoe trophy.
Now, i have just completed my third ending with Yes man and still no trophy, whats going on??
Anyone else had this problem? Any fixes?
