Nintendo first announced that the Nintendo Switch Online exclusive, Tetris 99, would be getting DLC back in May of this year with the Big Block DLC. This DLC featured two new modes into the game. The first mode was an offline Tetris 99 battle against bots. The second mode announced was an offline marathon mode. This mode is more similar to a traditional Tetris experience. Nintendo has just announced that the second wave of DLC for this game will feature offline multiplayer options. You will be able to play against your friends and family offline, likely through local play or co-op play. According to Nintendo, if you bought the original Big Block DLC, this next DLC will be available to you at no extra cost. The Big Block DLC cost $9.99 USD. This Downloadable Content will be available later this year to all Big Block DLC owners. It is unclear if this additional content will be available for purchase outside of the Big Block DLC.
The Tetris 99 digital game includes an online mode that is a special offer for Nintendo Switch Online members*. However, you can also get additional modes for Tetris® 99 as they are released with the one-time purchase of the Big Block DLC.
