Plot summary
The player controls Captain Viridian, who at the outset of VVVVVV must evacuate the spaceship along with the captain's crew when the ship becomes affected by "dimensional interference". The crew escapes through a teleporter on the ship; however, Captain Viridian is separated from the rest of the crew upon arrival. On returning to the ship, the Captain learns that the ship is trapped in an alternative dimension (referred to as "Dimension VVVVVV"), and that the ship's crew has been scattered throughout this dimension. The player's goal is to rescue the missing crew members and determine the cause of the dimensional interference.
