Ice blast.
Ice blast. A regular, classic one. With new effects it looks now more like an ice ball. Can also be done while in mid-air.
Ice shower
Another originated from MK3. This move is good as defensive at long ranges. Like an original one, can be directed in front or behind opponent as well.
Ice clone
One of the most effective close contact defensive moves. The clone itself was improved to look more like a real ice.
Upward ice blast
Based on Sub-Zero's MKM abilities. Is useful against approaching aerial threats, as well as against an airborne enemy.
Ground freeze
Looks very similar to classic ground freeze, but appears weaker a bit. During contact, enemy can not just stand on his feet, receiving no real damage.
Slide
Slide. Another classic move of both brothers. Is useful to slide under high attacks and projectiles.
Freeze run
Works much like freeze-at-contact from MKM. Sub-Zero runs forward, freezing everything in front of him. Is useful right after enemy's combo is successfully guarded.
Polaris
Based on famous polar blast move. The polar blast itself was not learned by a younger brother, so this move is weaker a bit. It generates a short-range freeze sphere around Sub-Zero, and is unblockable.
Breeze kick.
A new move, offensive and strong, is a good way to stop running foes. Is also a good way to defend one while a clone is deployed.
