Think you've seen everything there is to see in Batman: Arkham City after a few months of release? Rocksteady has revealed that there are three or four more secrets that have not been discovered yet. This was announced at London's Kapow! Comic Con by game director Sefton Hill during an IGN panel.
According to Hill, some of the most difficult puzzles were solved must faster than they though would be. "Some of them we put in there that were really obscure were found within a week (like the Scarecrow code). We didn't think anyone would ever solve that, but it only took people two days," he noted.
He then added, "But there are still 3 or 4 things that people haven't seen - some of them very subtle things. There's one that we had right in one of the first demos that we did that nobody has found - it's in there if you look hard enough."
Batman: Arkham City was released back in October 2011 and earned a perfect 10/10 score in Strategy Informer's .
