In MK2, Sub-Zero, like the other ninja character, all have a new costume design that they share by having different colours.
He stays with his Freeze and Slide special move, but his third special move allows him to Ground Freeze in front of him, causing his opponent to slide on it and be it in the process.
Against the CPU, Sub-Zero has to use his special move in specific situation. His opponent will always evade or block the move unless they are about to use their own special moves or when they are caught in the air. The same apply to the Ground Freeze. A viable technique is to do a jump kick, followed by the Ground Freeze and then followed by an uppercut. Another viable technique is to catch the CPU in the air and finish with his Slide. His roundhouse kick is also very fast, allowing him to hit his opponent twice and even three times before the CPU can fall down, but must be done in a corner. He shares that trait with Scorpion and Sub-Zero, since they share the same base character. It is also an excellent anti-air.
