Hope you haven't gotten your fill of Batman: Arkham Asylum, because Eidos is planning not one -- but at least two DLC packs for release in the next two weeks. According to SCEE's Mike Kebby, next week's free DLC will be entitled "Insane Night." "Prey in the Darkness" will follow one week later, on September 24.

It appears the upcoming expansions will be brand new, and won't be re-releases of pre-order exclusive DLC, such as "Dem Bones" and "Crime Alley." We don't know any other details on the two upcoming releases, but we do know this: we want them. Now.
