"The Riddler continues to taunt the Dark Knight with mind-bending puzzles and exploration challenges," Hill said, "but the location of his biggest secrets are known only to him and people he's told. Rather than unlocking their locations using maps, Batman will be able to scan a gang of thugs to find a potential informant."
We're excited about the new gameplay mechanic -- as well as the challenge, described by Hill, of making sure not to knock out the one guy in a crowd you need to talk to. But mostly we're happy for the Riddler. He's well on his way to figuring out the secret to successful crime: not immediately giving the world's greatest detective any clues about how to find your stash.
