Would you be willing to answer a few brief questions about PlayStation Forums?
I see people have a hard time reading. In the comments Omar said that they are undecided as to if the stage will be free or not. I hope it is and it should be but that doesn't mean it is.
There was another article that said Kat's level 3 would be her turning into the gravity panther. There will be AoE attacks and slashes from the panthers claws. So no need to worry about a cinematic level 3.
