Project 2 is Playdead's upcoming second game. It is said to be a spiritual succesor to Limbo. The game runs on the unity engine and is in 2.5D. It is said to be "crazier and weirder than Limbo" and uses some features originally cut from the game. Project 2 "tells the story of of a boy's struggle against evil forces trying to take over the world through questionable experiments on human bodies." It is supposed to be "more 3D than you would think."
