The Enemy Within continues to show the dark and dirty world that is Gotham City. While many of the characters from last season return looking just like they did by the time the first adventure ended, The Enigma introduces a few new faces, and their specific designs help to add to the overall feel of the game. The biggest addition that helps solidify the tone of the game is Riddler. He isn't a bowler-capped man in a green suit or leotard, but a man in a green hood whose iconic question mark cane comes to a sharp point, making it a far more obvious weapon than traditionally portrayed. The overall feel of Riddler really helps to remind players that Telltale's Batman series has a dark tone, and while it isn't anything to the level of Frank Miller's Batman, it's also much darker than Tim Burton's or Christopher Nolan's interpretations as well.
Audio-wise, the voice actors fit their roles quite well. Troy Baker continues his role as Batman/Bruce Wayne (as he has done for many games), while the supporting cast playing Alfred, Lucius Fox, Gordon, Riddler and other newcomers Amanda Waller and Special Agent Avesta all fit the bill.
