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.
In the PlayStation and Sega Saturn port of the game, the CPU seems to get caught by the freeze more often. This was not the case in the Arcade and version that have the same AI, has the CPU would avoid it in most circumstances, unless caught in the air or at the beginning of their attack. This makes it much easier to play as Sub-Zero and beat the game. His jump kick, followed by a slide is his main combo. His Ground Freeze is not used often because the CPU will mostly avoid it. His roundhouse kick is also very fast, allowing him to hit his opponent twice and even three times before he 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.
