In New Game Plus I finally beat Mr. Freeze, but this time I noticed that there were various statues of Nora around that I could destroy with a baterang or by dodging when he shot at me with one behind me. I tried destroying all that I could find, but it didn't seem to do anything. Is there a point to them or are they just eye candy?
During the fight, destroying the Nora statues irritates Freeze and indicates to him where you are. This could be used to draw him to a statue location and setup an attack.
