Well, finding all of Catwoman's trophies in the game plus finishing off the Museum helped me get over 400 trophies. I was able to find Riddlers hideout and got my achievement.
I was trying to perform one fighting move that catwoman has for an achievement. Once I get that, I will try some of the fighting parts but that will be it. I think I'm pretty much done with this game for all the achievements I'll be able to get in the game. I'm not going to run through it all over again for 2 more possible achievements.
