You choose a fighter from 90 characters out of Mario, Zelda, Pokémon, Star Fox, Kirby and other Nintendo series, then land on Riftwild Kingdom, an island of giant mushrooms and forests, or the original Sunreach Shores. A solo match fills the island with dozens of other fighters; you collect up to three guns, med kits and shields, and a shrinking circle pushes everyone together while a counter shows how many are left. You can also host a private lobby for friends. The game calls itself a non-commercial fan project. Allow about a minute for the first load, and play on a computer with a keyboard and mouse.
