Sonic Lost World is a platform game with action-adventure elements, in which the player controls Sonic the Hedgehog as he travels across the Lost Hex in order to rescue captured animals and stop the Deadly Six.[4] Levels range from side-scrolling 2D levels to fast-moving 3D linear levels to levels taking place on spherical worlds similar to the cancelled Sonic X-treme and the Super Mario Galaxy series.[5][6][7] This also translates to the 3DS version, as it was the first handheld game in the series presented entirely in 3D.[4]
