Nintendo has revealed that the Smash World service will be added to the Nintendo Switch Online app tomorrow, arriving alongside software update version 3.0.0.
You can easily view recommended videos and stages in Smash World without needing to start up the game, which will be streamed on YouTube in the app. You can also search for videos by fighter, and, if you see a stage that you like, you can queue it to download when you next boot up the mascot brawler.
You can also read in-game notifications in Smash World, or create new Spirit teams by using those that you have unlocked to add to your collection.
Super Smash Bros. Ultimate is now available exclusively for Nintendo Switch worldwide.
