In the game's original ending, Electro shouts "Top of the world!" after he departs his battle with Spider-Man and he goes to the North Tower of the World Trade Center, thus giving Spider-Man the clue he needs to track him down for the game's final battle. When the towers were destroyed on September 11, 2001, the game was quickly pulled and re-released with a new ending, in which Spider-Man just happens to correctly guess the unnamed building that Electro goes to for the game's final boss battle.
At the end of the video game, The Mighty Thor is credited with defeating Electro in the final battle. This is because Thor was supposed to appear in an video segment in the video game where he talks with Spider-Man shortly after he has defeated Hyper-Electro, thus giving Thor the credit with Electro's defeat in the Daily Bugle newspaper. This was removed because the game's original ending takes place atop the World Trade Center towers when the game was being developed and it was removed because of the towers' destruction on 9/11.
