DC has lifted the veil from the vague “Summer 2014” release date for their next animated feature, Batman: Assault on Arkham. You’ll be able to pick up the film on DVD, Blu Ray and Digital HD on August 12th, 2014. Batman: Assault on Arkham is set in the universe of the “Arkham” series of video games two years before the events of 2009’s Batman: Arkham Asylum, and features not only the Dark Knight, but popular rogues the Riddler, Penguin and Joker, as well as the Suicide Squad.
