Been playing the game for a bit now and I gotta say Batman's personality and voice acting (Following in the steps of Conroy) in this game completely suits the dark environment of the game and finally batman sounds like he's finally out for blood and the first encounter with slade..... 1 word...... EPIC!!!
Batman/Bruce's voice is done by the same guy who did Ezio in Assassin's Creed so I would expect it to be good
