You know, I imagined everything just as it is. There's something about these objects... they have Soviet soul. But, you wouldn't know anything about that...

— Miller

D6 (sometimes written as D-6, Russian: Д-6), also referred to as Metro 2, is a desolate top secret government/military facility, featured towards the later part of Metro 2033, and is prominently featured in Metro: Last Light. A focal point of the game's plot, it is in this sealed facility that Artyom must aid his companions in finding and arming the missile launching facilities outside Moscow, necessary to strike at the Dark Ones.

A location very similar to D6 is mentioned in Metro 2035, but the name itself is never used and the place is only referred to as a "bunker". It is an important strategic point that saw a massive attack from the Red Line happen, just like the Battle for D6, sometime between the events of the book and Metro 2034.

Located deep underground near the Barrikadnaya and Mayakovskaya Stations and west of Reich, D6 is a massive bunker-like facility whose access routes are well-hidden in the Metro, and existence is regarded as something of a legend among the underground dwellers. Information found at the Lenin Library allow Artyom, Miller, and a group of Rangers, each with their own specialty, to reach one of such entrances, located near Kievskaya Station. It could be presumed that said accesses are roughly similar to each other, consisting of massive airlocks concealing rooms used for storing machinery and spare equipment, gradually leading further underground, to what appears to be the remains of an old mine shaft. Even deeper are the only known ways into the facility itself, automated monorails which lead directly to D6 via tunnels separated from the metro. Said network is known as Metro-2, and unlike the main Metro is built on a monorail system instead of the standard two rail design. The Metro-2 network, being built deeper underground, is far more intact and traversable. It is unknown how far in each direction the network stretches, but there are at least six distinct lines and it is possible to directly reach Telesentr (the Ostankino TV tower) and the Botanical Gardens in the more northern part of the city from D6, which is located in the western portion somewhere under the Green Line. It is known that of all the Metro-2 lines (which are designated C1-C6), Line C5 heads eastwards, Line C3 heads north/northeast, and C4 heads southwards towards Kievskaya. It is likely the Metro-2 trains connect to the major government installations: FSB headquarters, Vnukovo Airport, the Kremlin, and other important surface facilities.


D6 itself is an enormous installation centered around a very large central shaft comprised of two main sectors and one smaller sector, each with four sub-sections: A1-A4, B1-B4, and D2. The perimeter of the shaft houses the Metro-2 automated monorails and the control station that directs electricity through the facility and controls the air re-circulation system. To descend into the facility proper, two rail carts can be utilized, spiraling downwards to the four main floors of the shaft:

  • Sector A is likely the Command and Control level, with a Command Center located in Subsector A1 and a larger one in A4. What A2 and A3 house is not revealed. It is in A1 where Artyom, Vladimir, Ulman and Miller head to activate the missiles to strike at the Dark Ones. Both command facilities are fairly identical with rows of computer banks with telephones, connected to systems that allow for command and control of outside military forces and facilities. Lighted maps of Moscow display the status of launching facilities and can be remotely accessed from this location. In Last Light, the Command Center in A4 is the main one, and is where Artyom receives his mission to kill the remaining Dark One in the Botanical Gardens. Direct elevator access to two of the Metro-2 monorails is available from this location, via elevators C3 and C4.
  • Sector B contains domiciles, storage and laboratories, where presumably the base's staff would reside and conduct other research. It is here that Artyom and the Rangers take up residence, in Subsector B2. The area is well equipped, with a kitchen, lounge areas, gymnasium, firing range and ample quarters. What B1 and B3 house is not revealed but it is likely to be additional access, storage and laboratories. Sector B4, as revealed in Last Light, is the place in which Dark Ones hibernate while their brethren were wiped out on the surface.
  • Sector D, the deepest part of the facility lies beneath the main shaft and can be accessed by an elevator marked D2 and is where its nuclear reactor and main generators lie, along with the control facilities necessary to maintain them. Elevator access directly to the monorail level is available from the reactor in case of elevator failure.

On every level of the facility are electric trams used for transport of personnel and materials, though most are inoperable after 20 years due to power failure. Massive sealed doors on all the floors of D6 apparently lead to unknown parts of the facility, including huge storage rooms filled with military hardware - tanks and other armored vehicles, missile launchers, including what appear to be RT-2UTTKh "Topol-M'" Mobile Intercontinental Ballistic Missile units, huge stashes of ammunition and weapons, and so on. If the weapons stored in D6 are not enough, the facility has remote control of many other missile launchers outside the D6, including the BM-30 Smerch mobile rocket launcher, although most facilities are destroyed before the Rangers' arrival, with only one unit in the outskirts of Southeastern Moscow being active.


Metro 2033[]

When Artyom and his group reach D6, the facility is sealed off and in a state of complete abandonment, its main facility filled with toxic gases, requiring the use of a gas mask, and completely lacks electricity. After a brief struggle with the main control station, Vladimir manages to reactivate the barest minimum to allow Artyom to manually reactivate the air filters and pump out the toxic air, which allows a complete restart of the main electric systems, including the control room of the lower floor. However, the back-up generators run dry shortly afterwards. Because of this setback, Artyom and Miller are forced to travel into the deepest bowels of the facility, which are flooded and infested by strange amoeba-like creatures, with a very huge specimen hindering access to the reactor. Artyom is forced to reactivate the nuclear reactor manually, during which the massive growth attacks him with a tentacle-like whip. After successfully re-activating it, the creature appears exhausted and dying, and Miller comments that after killing the Dark Ones, more Rangers will come to the area and 'finish the job'. While Artyom and Miller are heading to the tower, the rest of the Ranger group stayed in D6, preparing to launch the BM-30 missile strike against the Dark Ones.

D6 is only mentioned once in the novel, as Artyom does not visit it. Instead, Melnik, a group of commando Stalkers, and Anton go instead to start up the guided missiles.

D6 plays a pivotal role in Metro: Last Light. One year after the destruction of the Dark Ones, the Rangers have taken and fortified the military complex. It is the first location in which Artyom starts his mission. It also serves as his second home after Exhibition. In this time, D6 became revered in the metro as a place of wonder - where advanced technological miracles would soon be unearthed, that would save the people of the metro. Inside, however, appeared to only be more weapons to wage war with - and eventually an enemy thought dead. At this time of quieting disappointment, and unknown to the Rangers, a Red Army operative managed to sneak away with several biological weapons that General Korbut planned to use to bloodlessly conquer the whole metro.


Despite all attempts to stop the Red Line and reveal the Communist plot, the Rangers fail to prevent Korbut's plans to steal all the samples of the virus from D6. A massive battle for D6, and the climax of Metro: Last Light, has the Rangers of the Order and the Red Army warring on the platform, culminating in the inevitable loss of the Rangers. Battered and unable to fight the sheer number of enemies, Miller and Artyom execute a fail-safe contingency that will destroy D6 (with everyone in it) in order to save the metro from Korbut. The plan succeeds, or fails in the genuinely good way, depending on the Artyom's actions along the journey of the game. If the plan worked, as according to the standard C'est La Vie ending, D6 is destroyed, with all the Rangers, including Artyom, deemed martyrs for the metro. If the plan fails, it is because moments before Artyom is about to turn the switch of the detonator - the baby Dark One phases into view and stops Artyom, letting him know that he has returned with his kin, the hibernating Dark Ones mentioned briefly before the battle, to save them. In the Redemption ending, D6 and the Rangers are saved, along with the entire metro.

Metro Exodus[]

D6 appears briefly in the beginning of the game, as Artyom ventures to and from it, searching for an outside radio signal. After escaping the Metro and finding the "Ark" facility, Miller mentions that it is built exactly like D6, as both facilities were constructed using the same standard design. This allowed the Rangers to quickly regroup after being captured, and swiftly search the facility to find Anna.

Phew! That was close.

  • Given the desolated state of the facility, it could be speculated that it was abandoned and sealed soon after the Great War of 2013, as D6 was built to house conventional weapons and combat vehicles, as well as a storage place for experimental biological weapons. Thus, it likely only had enough rations for its personnel over a comparatively short time.
  • Both "D-6" and "Д-6" variants of the name are used in the game. It's justified as the cursive form of capital Д letter in Cyrillic alphabet looks like Latin D as the printed version is not comfortable enough to be written quickly.
  • Inside the D6 control, many Metro 2033 novels can be found.
  • The creatures infesting the D6 in Metro 2033 are no longer seen in Last Light. It's possible that they are wiped out by the Rangers. However, the Biomass may still exist, as implied from the conversation with the Rangers shortly after the beginning of the game. The Rangers seem to not return to the reactor area after Artyom and Miller restored the power.
  • Due to the large number of vehicles and weapons, it's possible that the Russians were preparing for a conventional invasion instead of a nuclear war.

In Real Life[]

D6, also known as Metro-2, is an underground transport system, which is used by the Russian government as a shelter. This system connects critical institutions of the government and military departments. Construction of D6 was started in the 1960s. Tunnels of this system can be used by trains and cars.
