Metro 2033 is a survival horror game (that uses the music from 28 Days Later in this trailer, strangely enough) from 2010.
After nuclear war, Russians have taken to using metro tunnels and stations to survive underground. Artyom, one of the first born in the metro, must get help for his station as strange creatures start to invade. But is that all they're after? Are they the only enemies to watch out for?
One year later, in Metro: Last Light, Artyom faces enemies in both the creatures and humans, as two factions fight for dominance and resources.
Though both are heavier on the action side, they still have interesting survival horror aspects to them.
Both Metro 2033 and Metro: Last Light are available on Steam.
