I have got some of the fighting ones with two bat medals, but just always seem to come up a lil short on getting the third.
The predator challenges are actually easier to get all three medals, as all you have to do is make sure you take at least 3 people out using the 3 methods specified. The only ones that are tough are the ones in the extreme challenges, like explode three walls at once, with each wall taking out at least one bad guy.
Still getting pissed off with that silent takedown trophy, as I have now done that 4 times and still wont get that trophy for some reason.
