Surprise! I'm not sure if it was announced prior to dropping, but a Knack 2 demo has just arrived globally on the PlayStation Store. It's 2.6gb in size and it's obviously free to download (not that we deserve it). You can grab it right here and begin the download so it's ready for you when you get home.\u00a0 It's hard to believe that Knack 2 is out next week. Knack was the first game to be revealed for PlayStation 4 and gamers have been glamouring for a sequel ever since. The hype will no doubt kick into gear now.
