Unleash your inner fighter in this unbelievable sporting event!
* Fight via simple motion and button controls Grab onto your Joy-Con with a unique "thumbs-up" grip and use simple motions and button presses to outthink your opponent. Toss and curve punches when you find an opening, and dodge a flurry of incoming attacks. It's fast-paced fun for everyone!
* Select from a variety of fighters Select from brand-new fighting superstars like Ribbon Girl, Master Mummy, and more! Each fighter has their own special attributes to learn and master.
* Fight in arenas with unique obstacles Throw punches around (or through) mysterious liquid-filled columns in a spooky laboratory, or in certain arenas, toss fighters onto trampolines for epic aerial skirmishes.
* Choose your arms carefully Each weapon has its own strength. Some are slow and do tons of damage, while others are fast as lighting, but will only serve to set up larger combinations. It's up to you to mix and match your arms to fit your play style.
