I recently got this game and I'm loving it to death, being a Batman fan and all that. It's rather easy, and somewhat kiddy, but still, it's charming, fun and has tons of unlockables. The thing is, I don't know how to select the characters I will have when I enter Free Mode. I can only select one, and the rest of the group seem to be picked up at random. Can anyone give me a hand with this thing? Thanks in advance.
