Nintendo has tweeted out two Tetris 99 announcements tonight. Nintendo says that you can now get the Tetris 99 Big Block DLC in the Switch eShop for $9.99. The DLC adds 2 offline modes, Marathon and CPU Battle. Not long after this was announced, Nintendo confimed that the 3rd Maximus Cup will be taking place starting on May 17th. This one will be special, because Nintendo is celebrating the 35th anniversary of Tetris. Everyone that earns 100 event points will get an in-game theme that is inspired by the Game Boy original. Both announcement tweets are down below.
