Not currently, but I know how it feels. I was playing with CF for about 4 months before I got the full game.
@Awesmic You have Core Fighters too? So you're just as limited as me I see. I'd figure you would have the full game.
I haven't bought a single thing for that FTP game. Besides having 4 main ninjas as free unlocks, I got Hitomi, Jan Lee, and Mila for free from TN's promotions for getting good reads from people downloading it, but I'm still limited.
