Metro 2033 DX11 gameplay performance and IQ compared

Metro 2033 is a first-person shooter survival horror game. It is set in Moscow after nuclear war has ravaged the surface. Most of the game is set in the metro system, which is a network of underground train tunnels. Obviously, the timeframe is the year 2033, and entire generations of citizens have grown up in the tunnels beneath Moscow. Metro 2033 eschews the traditional health meter; replace it with a regenerating health system indicated by visible blood splatters on the screen and an audible heart rate. Also important is the gas mask, which is required when the player leaves the tunnels and travels to the surface. The outside air is toxic, and the gas masks degrade and become damaged.
