In celebration of the 35th anniversary of Super Mario Bros. Nintendo announced Super Mario Bros. 35 during the Nintendo Mini Direct presentation that was held in September. Super Mario Bros. 35 is a take on the battle royale genre, starring everyone's favorite plumber. Along with Super Mario Bros. 35, Nintendo also announced the limited-edition Super Mario 3D All-Stars collection, which is a remake collection of the classic Super Mario games, including Super Mario 64, Super Mario Sunshine, and Super Mario Galaxy. Although the collection was well-received, fans were disappointed that it did not include Super Mario Galaxy 2. Just like the Super Mario 3D All-Stars collection, the Battle Royale is available only for a limited time.
Super Mario Bros. 35 pits 35 players against each other at once. Each player competes separately through the classic Super Mario Bros. 2D levels. Defeating enemies and collecting coins makes the game more difficult for other players, as it sends obstacles and enemies to other players' games. The last player standing wins the game. Although players can target other players manually, they can also choose to target players based on coins collected, players with the least amount of time on their hands, players attacking other players, or they can let the game target random players.
There's also a time limit per level and players can unlock more time by completing levels and defeating other players. Once players collect 20 coins, Super Mario Bros. 35 presents them with a Question Mark box that contains a random power-up. Players will also earn extra coins outside of the Battle Royale based on their placement. These coins can be used in leveling up Mario before heading to the next match.
Anyone with a Switch Online subscription can download Super Mario Bros. 35 from the Nintendo eShop. Although Super Mario Bros. 35 released on October 1, the game appeared at different timezones across different countries. The game takes up about 400MB of disk space.
Super Mario Bros. 35 will be available until March 31, 2021. This is also the same day when Super Mario Bros. 3D All-Stars will be discontinued.
