Donkey Kong Adventure is a 2018 tactical strategy expansion for Mario + Rabbids Kingdom Battle, developed by Ubisoft Milan for Nintendo Switch. Set apart from the base game, it follows Donkey Kong, Rabbid Peach, and a new character called Rabbid Cranky as they work to stop a power-hungry Rabbid Kong who has seized control of a mysterious island. The adventure unfolds across four distinct environments, each introducing new enemies and hidden secrets. Building on the turn-based tactical framework of the original game, the expansion reworks the combat mechanics to suit its new cast, offering a self-contained campaign that blends strategic grid-based battles with platforming and exploration. The addition of Rabbid Cranky brings a distinct personality to the trio, and the island setting provides a fresh backdrop that differentiates the experience from the main game's Mushroom Kingdom locations.
