The game continues on from the side-scrolling platform gameplay of Donkey Kong Country Returns, in which Donkey Kong and his companions must travel across a variety of levels to reclaim their home from vikings.
Along with Diddy Kong, who is equipped with his barrel jetpack for crossing large gaps, the game now features Dixie Kong, who can use her ponytail to gain extra height in the middle of her jump, and a yet unannounced character. Like the previous games, these characters can be played individually in multiplayer or serve as power-ups for Donkey Kong in the single player campaign. Dixie and Diddy appear to have individual DK Barrels, with Dixie's colored pink for identification.
The swimming mechanic, present in previous Donkey Kong Country games, makes a return, but in a refined fashion; players can now attack while underwater with a spin attack, and have a breathing bar right next to their health bar that appears as soon they get in the water. Players must touch bubbles in order to regain breath, or reach the surface (in a similar fashion to the Sega Genesis' Sonic the Hedgehog games).
A new game mechanic, lifted from Super Mario Bros. 2, Donkey Kong can now pluck things from the ground to reveal hidden secrets, as well as pick up and throw stunned enemies. There are also some sections that utilise a 3D perspective, such as when Donkey Kong is riding in cannon barrels.
