One of the rare story-driven first-person shooters, Metro: Last Light is based on the post-apocalyptic sci-fi novel Metro 2033 by Dmitry Glukhovsky. Rather than just pay lip service to Glukhovsky’s work, Last Light’s action exists to advance the plot, not provide spectacle. The developers meticulously created a believable burned-out version of Moscow. Crawling through the tunnels of the metro system—where mankind’s survivors now live—you’ll notice the rough texture on every rust barnacle or crumbled brick. The level of detail in the environments suspends disbelief better than just about anything else in the FPS genre, and makes the action—while admittedly a bit slower than the likes of Call of Duty—really matter.
