Metro.Last.Light

Metro: Last Light takes place one year after the events of Metro 2033, following the canonical ending in which Artyom chose to proceed with the missile strike against the Dark Ones. The Rangers have since occupied the D6 military facility, a huge pre-war bunker with miles of tunnels that have yet to be fully explored, with Artyom himself now an official Ranger. Despite their best efforts, word of D6 has spread around the Metro, with rumors that the bunker may contain enough supplies to sustain the Metro indefinitely. Tensions run high as the rival factions prepare for war in the hope of seizing the bunker and its contents for themselves.

Khan, a wandering mystic, arrives at D6 to inform Artyom and the Rangers that a single Dark One survived the missile strike. Khan believes that this Dark One is the key to humanity's future, and wants to make peace with it; Colonel Miller, the Ranger's leader, wants to eliminate it as a potential threat. Miller sends Artyom to the surface with the mission to kill the Dark One, accompanied by Anna, Miller's sarcastic daughter and the Rangers' best sniper.

Artyom succeeds in finding the Dark One, who turns out to be just a child, but is quickly captured by soldiers of the Fourth Reich and separated from the little Dark One. Pavel Morozov, a good-natured Red Line soldier, helps Artyom escape, and the two befriend each other after fighting through the Metro tunnels and across the devastated surface. When they reach a Red Line settlement, however, Pavel is revealed to be a high-ranking officer of the Red Line, who proceeds to detain Artyom to learn more about the Rangers and the Dark One.
