Play as pedestrian Peter Parker
When there is a mission available for the Daily Bugle, go to it. Go inside the building and talk to Robbie. When he assigns you a project, leave the building and go back in. You will notice the nav point is now showing up from inside the building. Wait up to seven minutes inside the building. You will get a mission failed (you wasted to much time, Eddie has taken your job). You have two options, "Retry" or "Do something else". Select "Do something else" and you should then appear on top of the Daily Bugle as Peter Parker. Walk over to the race on top of the building but do not start it. When you get the "Press A to start mission" message you will now have the ability to use A, which is punch. Walk over to the edge of the building and hold Forward and do uppercuts until Peter falls off the building. You are now Peter Parker in the city. All you can do is run around and punch or web. To exit this mode, die. When you respawn on top of the building go in the Daily Bugle and come back out. Note: This was only tested as Dark Spider-Man but should work for both forms.
