In a surprise Nintendo Direct presentation this morning, Nintendo announced a slew of games celebrating Mario’s 35th birthday. One of the most intriguing things on the menu is Super Mario Bros. 35, a battle royale-style reimagining of the original Super Mario Bros. game. Like the Tetris 99 battle royale game Nintendo released last year, Super Mario Bros. 35 doesn’t cost anything to play, but you do need a subscription to Nintendo’s Switch Online service.
