Metro Exodus,the third entry in Ukraine-founded studio 4A Games' Metro series, doesn't precisely have a novel premise. The world has been decimated by nuclear warfare. Survivors huddle in the ruins of Moscow's subway system, or forging a makeshift society out of the ruins of the traditional world. There are mutant animals and homicidal bandits. Everyone wears gas masks and crafts ammunition and pipe bombs from scrap metal while smoking cigarettes rolled from newspaper pages.
