I was hardly the first to express my initial distaste at the thought of Rayman’s detestable detractors – the Rabbids – crossing into Mario’s universe and shooting people. Things didn’t get better as Rabbid Peach was shown in promotional art looking… somewhat unhinged, and plenty of doubt was cast on the game. But much of that dissolves once you play it. Mario + Rabbids Kingdom Battle might be one of Mario’s most inventive and outside-of-the-box adventures to date, and the Rabbids actually make for fun characters for Mario and his pals to share their tale with.

As the story goes, a futuristic invention is fused with a Rabbid; and he, in turn, earns the ability to fuse things around him. A Rabbid with a cannon, or a paintbrush, or with a Piranha Plant, and much more. Using the futuristic technology they somehow find themselves in the Mushroom Kingdom, and the Rabbid culprit, named Spawny, is the source of the troubles. Led by BEEP-0, a sentient roomba, Mario and a couple of his new Rabbid pals set out to find Spawny and put the Mushroom Kingdom back to normal. And of course, the best method is to shoot a bunch of Rabbids.
