EW provide some details on what we can expect:
"In Arkham Manor, stately Wayne Manor gets made over into the local psycho dungeon, and, perhaps predictably, some inmates wind up dead. Things are a bit less bleak in Gotham Academy, a new monthly teen drama set at Gotham City’s most prestigious prep school. (Bruce Wayne is a benefactor; other familiar characters may pop up in Academy‘s twisted, teenybopping universe.)"
Arkham Manor is written by Gerry Duggan and drawn by Shawn Crystal and hits shelves October 1.
Gotham Academy is written by Becky Cloonan and Brendan Fletcher and drawn by Karl Kerschl, and will be with us October 22.
