So very stubbly.

Are you a bad enough dude to rescue this article?

Tetris 64 (not to be confused with The New Tetris, which is probably what you're looking for) is a Japan-only rendition of the classic game for the Nintendo 64.

Being from Japan, it has some weird features, such as the Bio Tetris mode which controls the speed of the game based on the player's heart rate, measured by a special accessory plugged into the controller and the player's ear... ouch!
