Following the recent release of Splatoon Raiders exclusively for the Switch 2, Nintendo has announced it will be hosting a new themed event in Tetris 99. If you boot up the Switch Online battle royale title between 7th - 10th August 2026, you can earn event points. As usual, once you've got 100 event points, you'll unlock a new theme featuring art, music and Tetrimino designs inspired by the new Splatoon adventure. In our review here on Nintendo Life, we called Splatoon Raiders the "best single-player Splatoon" with incredibly robust multiplayer options for anyone wanting to splat some Salmonids with family and friends. In case you missed it, Tetris 99 is currently hosting a limited-time discount on 41 collaborative themes until 17th August 2026.
