Hudson is developing another Tetris game. While Tetris Party added a bunch of multiplayer features, Tetris Axis for the Nintendo 3DS has a new gameplay modes. That’s one of the game’s "twists," the other is literal since the block dropping game is played with the board titled and twisted at an angle.
It appears the game will have 3D blocks flying out of the screen when you clear a line or stack blocks to get a tetris. Tetris Axis is slated for a summer release in Japan.
