DC Comics has announced a six-part comic series of Batman: Arkham City that'll bridge the gap between Arkham Asylum and the second game.
The first and second parts of the series will begin to go out in May. The comics will be written by Paul Dini, who's written Arkham Asylum and Arkham City. Concept artist of Arkham City Carlos D’anda will draw the comics.
The comics will be available in paper and digitally day-and-date for $2.99.
