You'll need a subscription to the Nintendo Switch Online service, though.
Super Mario Bros. 35, the Mario-themed battle royale game revealed in a Nintendo Direct presentation earlier this month, is available to download for Nintendo Switch Online subscribers now. It throws you into a 2D arena with 34 other players, all battling it out to be the last survivor.
It'll be available until March 31, 2021, just like Super Mario 3D All-Stars. For the next few days, Nintendo is running a special launch event.
"Test out your platforming skills on a limited selection of courses from Worlds 1 and 2 in Super Mario Bros. 35's first Special Battle event, running until 04/10!" the company tweeted Thursday.
