Cheat: If you type in "hcrayert" at the start of the game (which is treyarch spelled backwards). It brings you ahead to 40% of the game.
Trivia: For PS2, if you go to one of the eagle statues on the Chrysler building, you will see green and white feathers. In the previous Spider-Man game, a villain named Vulture had a costume with green and white feathers on it. In the Spider-Man game, you have to fight him on the Chrysler building. I guess some people don't want to clean things up even after two years.
