Metro 2033 (Xbox 360)

In the year 2013 almost all of humanity was wiped out as a result of a devastating war, and Earths surface became a nuclear wasteland. The few survivors in Moscow retreated to the citys subway tunnels. But even underground, human society continued to develop in predictable ways. Factions were formed, and stations and entire lines were occupied by ideologically opposed groups of people. War continued on a much smaller scale, adding to the difficulty of living under nearly impossible conditions, fearing the dark subway tunnels which harbored terrifying creatures.
