PlayStation 4 architect and Marble Madness creator Mike Cerny has announced a new game for Sony's upcoming console called Knack, which he'll be directing.Using Unreal Engine 4, Knack will star a little robot orc-looking thing that can sometimes turn into a hulking giant that looks a bit like Zelda antagonist Ganondorf if he were made out of building blocks.The art style is cartoony and recalls Cerny's last gen work on Ratchet & Clank and Jak & Daxter.We'll update as we find out more, get more assets, etc.
