Let's Play Metro 2033 (Redux) Part 13-Plan B

In 2013, nuclear war devastated the Earth, wiping out billions of lives. Among the affected nations is Russia, including the now-desolate wasteland of Moscow. A handful of survivors manage to hide in the Metro system, salvaging spare parts and growing mushrooms for food. Animals such as rats or bears have mutated into horrific monsters, while the air in many areas becomes heavily irradiated and impossible to survive in without a gas mask. There is a constant state of war between Stalinists and Nazis, while opportunistic bandits seize hostages and supplies in the metro tunnels. The Rangers emerge as a neutral peacekeeping force within the Metro.
By 2033, the northern station of VDNKh, now called Exhibition, is attacked by mysterious creatures called the Dark Ones. An elite Ranger named Hunter asks for support from a 24-year-old survivor named Artyom (Russian: Артём), the adopted son of the station commander. Before leaving to track the Dark Ones, Hunter gives Artyom his dog tags and tells him to present them to his superiors in Polis, the "capital" of the Metro.
