text: During the game, the player utilize a gameplay mechanic called "Viewtiful Switch" in order to swap between Joe and Silvia at any time. The two characters share both their amount of health and the VFX meter. Holding the switch button down for a certain amount of time enables the two player characters to use a special attack involving the transformable robot Six Machine. At intervals between stages, V-Points can be spent to purchase new moves for either Joe or Silvia, or to improve their existing powers, which includes making Joe's Mach Speed more effective or upgrading Silvia's Desperados. V-Points can additionally be spent to give the player more maximum health, add extra lives, or be used to buy power-ups such as the VFX Turbo Charger, which slows the drainage of the VFX Gauge.
  Aside from the main game, Viewtiful Joe 2 also contains an optional gameplay extra called the "36 Chambers of Viewtiful", a series of stages which test the player's skills. The objectives include defeating a set number of enemies or scoring a number of V-Points within a time limit, and dodging an onslaught of swords without dying.

  The plot of Viewtiful Joe 2 continues immediately from the ending of the previous game. Having just saved Movieland, Viewtiful Joe and his girlfriend (and new partner) Sexy Silvia learn from Captain Blue that the world will be threatened twice more. Joe and Silvia leave Captain Blue's space station to attend to an alien invasion from the forces of Gedow. The leader of Gedow, the Black Emperor, suddenly attacks Captain Blue and turns him into a statue called a "Rainbow Oscar", one of seven in a set that represents Movieland's power of the happy ending. With their power, the Black Emperor intends to conquer Movieland.
