Sonic: Lost World is an action adventure title and the second in a series of Sonic the Hedgehog titles that were originally exclusive to Nintendo eighth-generation platforms. The game blends 2D and 3D platforming mechanics, building on Sonic Colors.
Players control Sonic the Hedgehog himself through side-scrolling and 3D levels, with emphasis placed on managing his speed between slower and more deliberate movements to faster runs with access to parkour moves used to traverse up walls. Sonic can also gather Wisps, which like in Sonic Colors function as powerups that grant limited time benefits or special attacks. Players can also receive Wisps from other players through the Miiverse, which are more powerful than the regular versions earned ingame.
The game supports two-player coop multiplayer, where the second player controls a vehicle that assists Sonic throughout the levels of Lost Hex. Players can also race each other in competitive multiplayer modes.
