A high score run of Tetris: The Absolute - The Grand Master 2 PLUS' Normal mode, trying to get as high of a score as possible in 300 levels.
On Normal mode, there are 300 levels. Once you reach level 300, your timer stops and you get to continue playing in 20G mode for the credits roll. Surviving the 20G credits roll is not required to complete Normal mode, but it's always fun to continue playing and have fun with instant gravity. The last few videos I did of this game's Normal mode were speedruns. However the game actually keeps track of high scores for Normal mode instead. The ideal strategy is to try to get as many Bravos as possible since they reward you with a big score bonus. Most of the time that is not feasible, so the next best strategy is to make as big of a combo (i.e. consecutive line clears) as possible starting with a Tetris. Try to get as many big combos as possible within the 300 level limit to maximize the score you can get. Enjoy!
