Mario + Rabbids Kingdom Battle

Mario + Rabbids Kingdom Battle is a 2017 action-adventure tactical role-playing game developed by Ubisoft Milan and Ubisoft Paris and published by Ubisoft for the Nintendo Switch. A crossover between Nintendo's Mario and Ubisoft's Rabbids franchises, it follows Mario, his friends and the Rabbids, who must save the Mushroom Kingdom from the latter's invading brethren following their mishandling of an avid Mario fan's powerful invention in their world.

Mario + Rabbids Kingdom Battle was conceived in 2014 by Ubisoft Milan creative director Davide Soliani and Ubisoft brand producer Xavier Manzanares. The design objectives emphasized the dissonance of both franchises and creating a strategy game that stood out with unique elements. Its visual elements and animation were casual and vibrant and its music was composed by Grant Kirkhope. Although the game was met with poor reception when it was leaked, primarily due to its use of elements from the Rabbids franchise and weaponry, it was well received when it was officially announced at E3 2017.

The game's critical reception was overall positive, with praise towards its characters and turn-based combat and mixed responses to its puzzles and level-based combat. In 2018, a Donkey Kong-centric expansion pack for the game was released as downloadable content. A sequel, titled Mario + Rabbids Sparks of Hope, was released on 20 October 2022.
