The post-apocalypse is a popular setting in games, books, TV and. . . well, everywhere. But we've mostly been exposed to the American take on what comes after. Not so with Metro. Based on the titular Russian novels, the series somehow adds eastern fatalism with the desperation of the end times but manages to not depress gamers into self-mutilation. The second entry in the series, Last Light tightens up on the mechanics of its predecessor (2010's Metro 2033) and creates a grim but surprisingly beautiful world of the Moscow train system, humanity's only home fallen into ruin.
