Back in the U.S.S.R.
That's it. I promise. There will be no further Russian jokes or puns from here on out; Metro just doesn't support buffoonery at the expense of the motherland. Based on the book by Dmitry Glukhovsky, Metro 2033 introduced players to life after the bomb(s) where what remains of mankind survives underground and just can't catch a break. If radiation, horrifying mutants, and general shittiness of life don't bring you down, maybe the communists and nazis can. Hardened men fight in tunnels with hand-crafted firearms among other deadly weaponry, but you might still trip and impale yourself on the wreckage, or at the very least get a nasty bout of tetanus from the fall.
Metro: Last Light revisits Artyom, retains much of what made the first game great and introduces a cast of new characters. Have I mentioned that it looks absolutely jaw-dropping? I can't stress it enough, but that otherworldly fidelity has a major impact on gameplay too. I played this on PC and cranked my settings up, but even on lower settings textures, models, and effects impress. Despite minor complaints and moments of awkwardly forced titillation that nearly wreck its somber and engrossing atmosphere, Last Light proves exhilarating, haunting, and one of the best-looking games ever.
