Just downloaded the Joker DLC.

And for the most part, it looks like the Batman Challenge mode with the Joker.
There are of course some differences.

-The Joker doesn't seem to possess a batclaw so that is out of combat.
-He doesn't have a batarang, but a single bullet gun. Which is an instant kill.
-He fights cops and Arkham guards which is cool. The first level, one of the people you fight is Gordon.
-He throws poison/laughing gas instead of the cape stun Batman does.
-He has trippy glasses.

Now to see if different in Predator mode since assume has no batgrapple either.
