Here is an overview of the game, via Nintendo.com:
Microgame Mayhem Comes to the Nintendo Switch System
Take on over 200 quick and quirky microgames—lightning-fast minigames filled with frantic fun—solo or with a friend! When his latest harebrained business scheme goes awry, Wario must use his signature style (and smell) to fix it. How? By playing a twisted collection microgames of course! From assembling a robot to pulling out a statue’s armpit hair, the WarioWare: Get It Together! game is a comedic, cooperative microgame mashup.
Find a Friendly Frenzy with a Mountain of Microgames
Help out infamous game designer, Wario, after he gets sucked into his latest creation in Story Mode. Go it alone or with a friend in 2-player cooperative play—a first for the series! You can either play on the same system** or via local wireless.
Play as Wario and His Colorful Crew
For the first time, YOU control Wario and friends inside their own chaotic games. Use their distinctly absurd abilities to take on a rush of microgames. Tip a turtle with the help of Wario’s dash or choose Ashley and hurl a spell at it. In WarioWare: Get It Together!, mix and match characters and microgames for maximum fun!
WarioWare: Get It Together! is due out for Switch on September 10 worldwide.
