Metro: Last Light Redux is the sort-of-remastered version of 2013’s Metro: Last Light, which is the sequel to Metro 2033.
It is the year 2034. Beneath the ruins of post-apocalyptic Moscow, in the tunnels of the Metro, the remnants of mankind are besieged by deadly threats from outside – and within. Mutants stalk the catacombs beneath the desolate surface, and hunt amidst the poisoned skies above.Game Description
