Crash Bandicoot 2: N-Tranced is a platform game in which the player controls Crash Bandicoot, who must free his friends from the hypnosis of the main antagonists of the story. Much of the game takes place in a dimensional bubble that Crash and his mentor Aku Aku are trapped in. The inside of the bubble is displayed as a map littered with portals to different levels. Connecting the portals are dotted lines which Crash can use to travel between portals; initially, only a few dotted lines are visible. The goal of each level is to find and obtain any Crystals and Gems hidden in the area. As more Crystals are retrieved from the levels, more dotted lines will become visible on the map, allowing for further exploration. Gems allow access to special levels necessary for full completion of the game. When the antagonists of the game have been defeated and enough Crystals have been gathered to return to Earth, the game is won.
