Mario + Rabbids Kingdom Battle

More details on Mario + Rabbids Kingdom Battle have leaked via, who first leaked the still unannounced Switch RPG’s key art last week.

Here’s everything the site knows, according to its sources:


  • Development began three years ago (2014). Ubisoft approached Nintendo with the proposal using the standard pitching process for a game to be greenlit at Nintendo.
  • Multiple Ubisoft representatives have claimed that to see prototypes of a Wii U version of the game at various points in development, suggesting it was once planned for Wii U.
  • While the game is being made by both Ubisoft Paris and Ubisoft Milan, the latter is handling the core creative direction.


  • Nintendo has closely overseen the project, and their approval is required for anything concerning the use of their characters, but most of Ubisoft’s ideas have been met with little resistance.
  • In an early prototype, there was a boss battle against a Donkey Kong-themed rabbid, which has access to a pile of bananas it can use to replenish its health. Players need to cut off its banana supply to prevent it from replenishing its health before they can deal any real damage. The boss will dab periodically if it properly lands an attack. Once it is defeated, the Princess Peach-themed rabbid in the player’s party pulls out a smartphone and takes a selfie with the boss before it collapses.

Game Details

  • Mario has a passive ability which enables him to automatically fire at an enemy if they enter his field of vision during the enemy’s turn.
  • Princess Peach has the powerful ability to inflate enemies using a foot pump until they explode.
  • Some skills are common across multiple characters.
  • The campaign is expected to be 20 hours or so long.
  • Sources recall indications that an online mode was being tested several months back, although this mode was inaccessible in said test builds. The full game will at least offer two-player local co-op. An additional “Arena” mode was also spotted in the test user interface, promising local co-op action.


  • Amiibo support is planned. There is an apparent “Amiibo Machine” feature, but its functionality is not yet clear.
  • Multiple sources claim Ubisoft has been producing prototype figurines of some of the game’s characters.
