Sonya is identical to her Ultimate Mortal Kombat 3 form. She doesn’t gain any new move or animation.
Sonya has many arsenals in her move sets. He Energy Rings can push opponent away and her Wave Punch is an excellent anti-air. The diagonal Bicycle Kick can catch airborne opponent that are about to do their move as well. Her leg throw, like in MK1, is considered her strong move because of how fast she can do it as well as going through most basic move. She also has a high assortment of combo that are suited to many different situations.
Against the CPU, Sonya doesn’t have many options. Her Bicycle Kick and her Energy Rings are too slow and will be countered by her opponent, especially later in the tower. It is also very hard, if not impossible to mix combo with special move unless you get them in the corner. In short, Sonya has to relies on combo that are started with a jump punch or a neutral jump kick. However, well placed Square Punch and Leg Throw can be useful against jumping and running opponent, respectively.
No cheats were used in the run. However, some flaw in the game were exploited against the CPU. TAS tools were used to make a high-quality gameplay.
