Factory (Donkey Kong Country Returns)

The Factory is the seventh world of Donkey Kong Country Returns and can be accessed after defeating Thugly. It is located on Donkey Kong island, and is a very industrial area. During the events of the game, it is infested by members of the Tiki Tak Tribe who have stolen Donkey Kong's and Diddy Kong's Banana Hoard. When the Kongs first arrive in the Factory, the entire area is covered in a thick blanket of smoke. Only by activating the fans in Foggy Fumes, the Factory's first level, will the smoke be blown away.

The Factory is an industrial and mechanical area. It features many new elements not seen in the game's previous worlds, such as moving platforms that tilt, conveyor belts, and many robotic constructions that can hinder or help the Kongs. There are platforms that can crush Donkey Kong and Diddy Kong and there are also platforms that disappear and reappear when certain switches are touched. The area is also unique because in levels 5, 6, and 7, players will need to find a giant red switch in each level. If players do not find every switch, they cannot access the next level, meaning they cannot move on.

The Factory is extremely complex. As the Kongs journey throughout the early levels of the Factory, vegetation is seen growing in the warehouses and biuldings, there are also large windows that show out side of the Factory, much like Slammin' Steel. Lift-off Launch shows a large jungle area outside the factory, showing that the area the Factory was built on could have once been like the Jungle the game begins in. Later levels rarely show plant life, and are mostly dark desolate rooms filled with giant mechanics, such as pile drivers, hammaers, gears, pipes, and robotic hands that used for various means of work. There is also a space ship station that is used in order to reach the factory buildings where Colonel Pluck is located.

The enemies in this world are mainly robotic and attack using fire, electricity, or by exploding.
