Donkey Kong Country Returns

Donkey Kong Country Returns with the classic side-scrolling play that made the original so popular, now rendered with new levels and vibrant 3D environments. When Donkey Kong's banana stash is stolen, he goes on a quest to get them back. This time, Diddy Kong joins the adventure, opening up the franchise's first opportunity for simultaneous co-op play. Diddy can hop on and off Donkey Kong's back any time, giving rookies a chance to ride along when the going gets too tough.
