Hey Im trying to do all the E Nigma parts and when I get to the holding cells there is a green question mark that floats between both sides of the room but I don't know what it is its not a riddle puzzle because nothing comes up anyone know what it is?
that's in the penitentiary. just go in the guard room and there is vent there that i think you could take down with a batclaw or it could be open. i forgot. --- not changing this sig until the Chargers win the Super Bowl 11/26/07 PSN: Maddgikman
actually you have to go down the elevator shaft. that question mark is the riddle about the "jonathon crane elevated fear blah blah." theres a vent there at the bottom, pull it off crawl and hold l2 to scan the scarcrow room. and voila! one riddle solved.
