Metro Redux refers to both Metro 2033 Redux and Metro: Last Light Redux. These are remade versions of Metro 2033 and Last Light; we reviewed the latter here. Metro 2033 Redux shows noted improvement over the original in terms of visual fidelity. Last Light Redux on the other hand shows some downgrades, with some of the tessellation from the original being removed. On the other hand it has a small amount of global illumination that isn’t present in the original.
