Call of Duty: Black Ops Cold War: From Amsterdam to Solovetsky

The campaign opens in an Amsterdam bar in January 1981, where Adler, Mason and Woods are closing in on Qasim Javadi. Javadi escapes onto the rooftops; the interrogation that follows points them to Arash Kadivar. The bar and rooftops are the game's, but the setting is De Wallen, Amsterdam's largest and best-known red-light district: a network of narrow alleys and red-lit windows. It is still one of the city's main tourist attractions.

Location precision: The mission's bar and rooftops are invented; the pin marks De Wallen, the red-light district the level recreates.

Visitor guidance: De Wallen is Amsterdam's red-light district and one of the city's main tourist attractions.

The Vietnam flashback relives Operation Fracture Jaw, the 1968 operation where Adler says he, Bell and Sims first met Perseus. Its final sequence is a helicopter run up a canyon to a firebase the game calls Ripcord. The real Firebase Ripcord, in the A Shau Valley, was besieged for 23 days in July 1970; 75 American soldiers were killed before it was abandoned. The game's 1968 date and the real 1970 battle do not match. The mission's name comes from a top-secret plan to move nuclear weapons into South Vietnam.

Location precision: The game names a Firebase Ripcord in its 1968 flashback; the pin marks the real firebase in the A Shau Valley, fought over in 1970.

The team crosses into East Berlin to find Anton Volkov, the Russian mobster who helped Perseus smuggle a nuclear device through the divided city. The mission's East Berlin is the game's, but the Wall is not: it encircled West Berlin from 1961 to 1989, with guard towers and a death strip of anti-vehicle trenches and beds of nails. Construction began on 13 August 1961. A long stretch along the Spree survives as the East Side Gallery.

Location precision: The mission's East Berlin streets are invented; the pin marks the Wall that divided the city.

Visitor guidance: The East Side Gallery preserves a long stretch of the Wall along the Spree near the Oberbaumbrücke.

Next, Adler and Bell infiltrate the Lubyanka Building to steal the list of sleeper agents. The real Lubyanka, a Neo-Baroque block on Lubyanka Square, was the KGB's headquarters and held a prison that became operational in 1920; its inmates included Osip Mandelstam and Raoul Wallenberg. Today it houses the FSB, a KGB museum and a prison museum, though visits need special authorization. The break-in is the game's; the building is not.

The trail of a Greenlight scientist leads the team to Cuba, where the mission ends in a firefight; Lazar and Park are wounded, and Bell can save only one. The game names only Cuba, not a town. Havana, the capital and largest city, was reshaped by the 1959 revolution and the U.S. embargo of 1960, which hit the city hard. The firefight is the game's, but the alliance behind it is not: Cuba and the Soviet Union had close relations.

Location precision: The game names only Cuba; the pin marks Havana, the capital, and not the mission's unnamed action site.

Visitor guidance: Havana is Cuba's capital; Old Havana was declared a UNESCO World Heritage Site in 1982.

If Bell tells Adler the truth, the CIA assaults Perseus's headquarters in the Solovetsky Islands, racing to destroy the transmitters that would detonate the Greenlight bombs. The final mission opens with an approach by vehicle and an EMP that knocks out the radio towers. The real Solovetsky Monastery was founded in 1436, became one of northern Russia's largest citadels, and from 1926 to 1939 served as a Soviet prison camp, a prototype for the Gulag. Its walls are 8 to 11 metres high, and UNESCO lists the site.

Visitor guidance: The monastery is an active religious house and a museum on Solovetsky Island in the White Sea.

Lie to Adler and the team flies to the Duga radar array in Ukraine, too far away to stop Perseus from activating the nukes. This is the campaign's other ending, and the array is real. Duga was a Soviet over-the-horizon radar that operated from 1976 to 1989; its antenna spanned 700 metres and stood 150 metres high, earning it the nickname Russian Woodpecker. The receiver is 12 kilometres west-north-west of Chernobyl.
