Ultimate addon - Crysis

Earth, 2019. A team of US scientists makes a frightening discovery on an island in the South China Sea, and all contact with them is lost when the North Korean government quickly seals off the area. The United States responds by dispatching an elite team of nanotech-suited Delta Force operatives, and tensions quickly rise to boiling point. But when a massive alien ship reveals itself in the middle of the island, generating an immense force sphere that freezes a vast portion of the area, the two warring factions must unite, fighting epic battles through tropical jungle, flash-frozen wastes, and finally in the heart of the alien ship itself for the ultimate zero-G showdown.
