Batman: Assault on Arkham - Region 1

When the government teams up a group of supervillains with the code name Suicide Squad and forces them to break into Arkham Asylum to bring back top secret information the Riddler has stolen, Batman soon becomes involved. But things go from bad to worse when one of the Squad (Harley Quinn) frees the Joker, who has the means to not only blow up the asylum, but most of Gotham City as well.
