Spider-Man: Friend or Foe Cheats and Unlockables (PSP)

Spider-Man: Friend or Foe challenges players to defeat and then join forces with notorious movie nemeses including Doc Ock, Green Goblin, Venom and Sandman, as well as with other classic Spider-Man characters. Players will embark on a global quest to overcome an evil threat, by controlling Spider-Man and one of the numerous Super Hero or Super Villain sidekicks, as they master unique fighting moves and styles while switching between characters to execute team combos and defeat foes.

Spider-Man: Friend or Foe features a unique co-op mode in which a friend can join the game at any time and take control of Spidey's sidekick as they battle through the game side-by-side and replay favorite levels.

 
In an opening cutscene, Spider-Man finds himself beset by the villains of the first three movies, gaining help from Harry Osborn as he fights the Green Goblin, Doctor Octopus, Sandman and Venom. However, all six characters suddenly find themselves targeted by an enemy force and one-by-one, the villains start disappearing. Meanwhile, Spider-Man is rescued by Nick Fury of SHIELD, who informs him that the meteor that brought the Venom symbiote to Earth had broken up in Earth's atmosphere and five more pieces had landed in various locations across the globe.
