You can reach out and slap other players in LBP Karting
Some screenshots of United Front Games' LittleBigPlanet Karting are posted below courtesy of AGB. Also, Polygon has some gameplay details for you: the LBP grappling hook mechanic returns; a hover chassis is implemented on the cars; it contains quests such as finding hidden items, hide n' go seek, and waypoint races; it has an eight-player battle area; asynchronous multiplayer for user-made tracks is included; and an expanded Pod will allow players to travel between modes and perform various customization options. You can also turn any in-game object into a weapon or paint one into the game as well as reach out and slap other players in order to stun them. Sounds fun. Game's out in October on PS3.
