"Subway: a semi-nutritious alternative to fast food, or post-nuke Russian refuge? Metro 2033 lobbies for the latter, letting us play in an apocalypse where affordable footlong sandwiches are forgotten luxuries of a dead, Jared-less era.

Breeds of psychically inclined supermutants roam the wastes above, and lucky you: you're one of the brave few able to venture back to the surface for supplies."
