I beat the whole game,got all the collectables etc. so I decide to beat the game on hard,I go back to the apartment,put the game on hard and go through all the missions and beat the game again but for some reason I don't get the trophy for it.Is that some kind of glitch?
Did you start a new game, or just set the difficulty level higher? You may have to start over.
Source: I dunno, I've never played the game but I just want to help!
I would start a new game but that deletes all of your previous data which means I would have to collect those 700 comic book pages etc. all over again.
