Scribblenauts Unlimited is a side-scrolling Puzzle game with a substantial Action component, in which players use a magical in-game notepad to create objects that are used to complete tasks and challenges that are placed before them. Once created, objects are stored in the game's object library, and can be resummoned using their given name, and even altered for use later. Additional features include: the return of the series hero, Maxwell, now with a deeper storyline; an open world game design featuring themed play areas; hint functionality; and 3DS StreetPass functionality that allows created objects to be shared wirelessly with other nearby players.
