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: At the beginning of the game (introduction), the camera moves around all through the city while Peter Parker is narrating. When the camera moves around the Chrysler Building, you can see a black figure standing on the top. That figure is Black Cat, who teams up with you later in the game.
