Knack’s companion app is now available as a free download on iOS. Knack’s Quest is a puzzle game tasking the player with collecting three or more matching parts for the mechanical beast. The more you collect, the larger Knack becomes – you much reach his size limit and complete the stage before time run outs. The items you discover can be used with the PlayStation 4 title when it launches alongside the console next week in North America and November 29 in Europe. Thanks, Videogamer.
