Back in the early 1990s, after the world had gone mad for Tetris, Nintendo put out its own variant of the puzzle game that, unlike most clones of the day, actually brought some new life to the original idea. Now the classic Nintendo game, with some improvements of its own, is reintroduced for the Nintendo 64. Rather than just twisting shapes to fill vacant spaces, Dr. Mario 64 will have you matching capsule-shaped pills to fight like-colored viruses. Players earn point bonuses when stringing combos together. Dr. Mario 64 comes with the original one- and two-player modes, and introduces a simultaneous four-player mode.
