If you remember the leak we covered long time ago, one of the games listed for the Nintendo 3DS was called ADVENTURE TIME 3 :
It is indeed the third game released on the console, however, its name is actually Adventure Time: The Secret of the Nameless Kingdom.
The game was developed by WayForward again, and the publisher (Little Orbit) gave more details about the title. Adventure Time: The Secret of the Nameless Kingdom will debut on Nintendo 3DS, PlayStation 3, Xbox 360 and Steam this November, just like the picture announced. There’s no word about a Wii U release.
Players will be taking on the roles of both Finn and Jake as they navigate through the eponymous kingdom – a mysterious unexplored region in the Land of Ooo. The two characters will find hidden secrets by exploring all corners of a brand new kingdom made just for the game and encounter never-seen-before characters and creatures.
