We've seen Batman: Arkham City villain trailers featuring Catwoman, The Riddler, The Penguin, and Mr. Freeze but with less than a month to go until the game's release, it's time to give a trailer to Bats' biggest bad, The Joker.  The Joker was running the show in Batman: Arkham Asylum but from what we know so far, it looks like Dr. Hugo Strange is in charge of Arkham City.  The new video game is packed to the gills with Batman's foes (in addition to the aforementioned rogues, there's also Harley Quinn, Two-Face, Poison Ivy, Calendar Man, Victor Zsasz, Talia al Ghul, Solomon Grundy, and Deadshot), but I refuse to believe that developer Rocksteady would make Joker just another baddie.We'll all find out when Batman: Arkham City is released on Xbox 360 and PlayStation 3 on October 18th.  Hit the jump to check out the new trailer.Trailer via MTV.
