Metro 2033 Redux comes from 4A Games and Deep Silver. Here’s how they describe it:
In 2013, the world was devastated by an apocalyptic event, annihilating almost all mankind and turning the earth’s surface into a poisonous wasteland. A handful of survivors took refuge in the depths of the Moscow underground, and human civilization entered a new Dark Age.
