Tetris the Grand Master 3 has the subtitle “Terror-Instinct”. KevinDDR has become the sixth player in the world and the first outside Japan to tame this beast and earn the rank of Grand Master in Classic Master mode. Only the best players who can get to and and beat the invisible credits roll consistently earn the right be tested for Grand Master rank, and Kevin pulled it off under pressure. Congratulations!
Update: Replaced the unofficial AGDQ YouTube archive with the official one.
