Ubisoft announced today at their E3 2018 press conference that the Mario + Rabbids: Kingdom Battle — Donkey Kong Adventure will release for Nintendo Switch on June 26.

The adventure stars everyone’s favorite necktied gorilla, Donkey Kong. But he won’t be alone. Rabbid Peach and Rabbid Cranky Kong — who is also making his Mario + Rabbids: Kingdom Battle debut in this DLC — will join Donkey in this expanded adventure.
