THIS IS A MOD AND A COMBINATION OF THE LEGO MONSTER FIGHTERS SETS AND THE OFFICIAL LEGO ARKHAM ASYLUM, I WANT HAD MORE CRYSTAL PIECES FOR THE LOWER FLOOR BUT IT LOOKS WELL ANYWAY , I BUILT IT TO HAVE A PAREIDOLY WITH THE MAIN BUILDING AND SO BE ABLE TO PUT THE FACE OF THE JOKER LIKE IN THE ARKHAM ASYLUM GAME, I PUT THE BANE MASK IN THE SECOND FLOOR, IT SUPPOSED TO BE THE MASK THAT HE USED ON IN THE BATMAN THE DARK KNIGHT RISES, BUT IT'S AN UNOFFICIAL LEGO PIECE SO I LEFT THE MASK FROM A MINIFIGURE.
