Nintendo is turning the original Super Mario Bros. into a 35-player battle royale game called Super Mario Bros. 35, available on October 1st exclusively to Nintendo Switch Online subscribers. Super Mario Bros. 35 looks to offer a similar design to Tetris 99, another Switch Online-exclusive battle royale. In the Mario version, all 35 players will play through a Mario level simultaneously until only one player is left standing. Any enemies that you defeat in your version of the level will be sent over to other players for them to deal with.
