Mario + Rabbids Kingdom Battle appears on Amazon, Walmart; August release

The Nintendo Switch's worst kept secret.

Mario + Rabbids Kingdom Battle has been a poorly kept secret for a while now, but it looks like even Walmart and Amazon want to get in on the leaks. The game, which is a collaboration between Nintendo and Ubisoft, has begun appearing in online stores. 

Amazon Spain has listed the game with an August 29th (supported by another leak) release date and Walmart has listed the game with no details other than there being a 'Day 1 Edition' of the game.

Previous rumors have suggested amiibo support for the game, as well as a turn-based combat system, two-player local co-op, and a humorous tone to its narrative. On top of that, Mario, Luigi, Yoshii, Peach and four Rabbids disguised as the previously listed Nintendo characters will be playable.
