A sequel, Knack 2, was released on September 5, 2017.
During the game, Knack discovers that he has a skill (hence, knack) that allows him to incorporate ice, metal and other substances into his body, giving him new abilities from level to level. Sony describes the gameplay as "a little bit like Crash Bandicoot and Katamari Damacy, with a touch of God of War". The combat is really simple because all you have to do is avoid and kick some butt! Collect sun stones and whatever element it saids. There are 13 chapters that are not too hard also inculding the final boss which is a piece of cake.
War has been brought against mankind by a resurgent species known as Goblins, led by Gundahar. A human doctor, who studied ancient relics from a long lost civilization for many years, finally found a way to bind them together and give them consciousness. The result was Knack, a creature with mysterious powers. For example, he can incorporate more relics into his body as he finds them, which allows him to transform from a three-foot tall creature into a gigantic wrecking machine. The doctor believes that Knack will be an invaluable asset in the war against the Goblins, until it becomes clear that an even greater danger is posed by elements of the human community. Thus, leading you on a epic journey filled with whipping some major butt.
