In the trailers for the game it says that you can go into the sewers and into the subway. You can do this during the game but once you have completed it you no longer have access to them. Why is this? Also you no longer have access to the black suit spiderman outfit once you have completed the game. I heard you have to collect all Spidy Emblems to get it but I can't seem to find any. Where are they and what do they look like?
