Earth is the original home for humanity, and is the third planet from the Sun in the Sol System. At some time in the future the Earth's crust was unable to further support humanity, and the remaining humans built giant orbitals around the Earth as their new home. The Earth orbitals still remain the political and military head of humanity and mines still operate on Earth.
N.O.V.A. 3 starts off in the abandoned city of San Francisco, with Kal Wardin fighting through hordes of Volterites as he moves around the city looking for Yelena. During this level a good view of the current condition that Earth is in is seen with the majority of San Francisco's infrastructure still intact.
