Puyo Puyo Tetris from Sega mashes two classic puzzle games together. In Versus mode one player plays Tetris while the other drops puyos. The Puyo Puyo side follows the rules of Puyo Puyo Tsu so when you erase puyos you drop nuisance puyos on the other player’s board. The Tetris side uses classic Tetris rules.
Sega also created a swap mode where you have two game boards, one for Tetris and one for Puyo Puyo. When clock runs out the boards switch and both players change games.
Puyo Puyo Tetris comes out on February 6, 2014 for Wii U, PlayStation 3, Nintendo 3DS, and PlayStation Vita. It’s been awhile since Sega brought a Puyo Puyo game to the West, but I’d say this has a fair chance of being localized because Tetris is in it. Interestingly, the last English Puyo Puyo game was Puyo Pop Fever which was published by Atlus USA.
