After the Lingshan Islands incident, multiple areas dubbed "cold spots" by the US military have appeared all over the surface of the earth. The cause of these cold spots is unknown; there are no patterns to their appearance, and more importantly, there is no known way to remove them. As demonstrated by the first contact, sheer military force is not enough to destroy the spheres that form the protective outer shell for these locations, and the temperatures are low enough to flash freeze any standard infantry deployed inside them.

Adapt
Cue the US attempt at creating the Nanosuit. Able to survive extremes in temperature, it forms the perfect response task force. However, the Korean People's Army are still developing their implementation of the nanosuit and are also attempting to secure these locations in an effort to acquire the alien technology and presumably learn from it, due to their failure on the Lingshan Islands.

Engage
That's where you come in. Equipped with the latest and greatest gear, including a nanosuit and all the high tech weaponry you can carry, you, along with four other NanoSoldiers, are sent to deal with one of the hazardous environmental phenomena. Escorted by several Navy ships, you will make your way to the island in question.

Survive
No plan survives initial contact. That saying still holds true to this situation. With your boat destroyed whilst approaching shore, and all communications blocked, you and your team must stay on mission: remove the KPA forces from the island, figure out the cause of the sphere, and eliminate what could be the most grave threat to humanity in its entire history...
