The Riddler is coming back, and he's even more sadistic than before.
Remember how, in Batman: Arkham Asylum, the Riddler harassed the Dark Knight throughout the entire game without actually making an appearance? Well, it turns out he'll be returning in the upcoming sequel, and he's going to have an even bigger, nastier role in the game.
According to Joystiq, Edward Nigma is still going to be challenging players with devious puzzles, but things will take a definite Jigsaw Killer turn: Failing to solve the puzzles results in the deaths of innocent Gotham City citizens.
The revelation apparently came about in a press preview from GDC, but "WBIE's being stingy with the assets," so the character's not on display for the public, yet. Apparently the PR group in charge of Arkham City has said the video will be made available at a "later date."
The Riddler's always been one of my favorite villains in the DC Universe, especially when he recently became such a nasty piece of work after the "Hush" storyline (but before he was reformed and just became an obnoxious berk). I'm not going to lie: The thought of him as a ruthless killer who uses crazy deathtraps to toy with Batman is pretty sexy.
