Spider-Man 2: Enter Electro is an action-adventure video game based on the Marvel Comics superhero Spider-Man. It was developed by Vicarious Visions, published by Activision, and released for the PlayStation in October 2001. It is the sequel to Neversoft's 2000 Spider-Man game, and directly follows the events of that game, as Spider-Man tries to stop Electro from becoming all-powerful using a mechanism called the Bio-Nexus Device. Like its predecessor, the game features several classic Spider-Man villains as bosses, including the Shocker, Hammerhead, the Lizard, Sandman, and Electro, as well as his charged-up Hyper-Electro persona, created exclusively for the game. Enter Electro received moderate favorable reviews, with critics generally considering it to be a downgrade from its predecessor. The game gained some fame for having its final level modified after the September 11 attacks; originally set to take place on top of the World Trade Center, the setting was later changed to a generic skyscraper. The game was followed by Spider-Man: The Movie for the home game consoles, based on the film that released in 2002, while a standalone sequel for the Game Boy Advance, Spider-Man: Mysterio's Menace, was released in September 2001.
