Ok guys need your help. I'm told by the guide I have that I need 400 Riddler secrets to open the final mission with Riddler. I have two riddles and 3 demon seals in Wonder Tower to get, and that's it. When I get these, I'll only have 383 secrets. According to the menu for the Riddler secrets, I have every other one that's available to Batman in every single area, from Park Row to Wonder City and everything in between. All the trophies, all the riddles, all the breakable items (cameras, balloons, etc). All of it, again according to the ? menu.
So what's the deal? Do I have to have Catwoman trophies too? That seems so unreasonable since her part of the game is extra DLC. But if it's not the Catwoman trophies, what the hell else can it be?
Luckily the Catwoman trophies are easier to get, I just finished getting all the trophies myself, I left hers for last since they were easier to get - and weren't that many compared to Batman.
