We all knew it would come down to this eventually. Whenever two costumed men clash as violently as Batman and the Joker did in The Dark Knight, it always ended up as a breakdancing fight. So hit play, then choose your character, and follow the instructions to see if good or evil triumphs in the end -- you'll be taken to YouTube, but it's well worth the trip. Either way, moves will be busted, my friends, and likely a few grooves as well. Thanks to MyNoNos for the tip.
