Tunguska is the fourth area visited by Crypto in Destroy All Humans! 2, and is the home of the KGB. The area is infested with Blisk and Blisk Mutants. It is a snowy nuclear power driven land, covered in miserable people, Army Soldiers, and KGB agents.
In 1908, a large Blisk Warship crash landed in Tunguska, creating a massive air burst across the land. Fearing for the survival of his species, the Blisk leader infiltrated the Soviet government and placed himself as it's leader after Stalin's death. Once in power, the Blisk leader, now going by the name Milenkov, began to have his Blisk warriors either excrete or create Spores to mutate the humans into their soldiers. Over the course of years, the Blisk had gained a prominent hold over the Soviet Union, had tricked them into transporting them to the Moon, and into helping them reconstruct their species and society. Shortly after, agents Natalya Ivanova and Sergei had become aware that something was wrong with the government. While Sergei was dealing with what was happening in Russia, Natalya enlisted Crypto's help in exposing the KGB and their plans.
After learning of the KGB's plans to infect every country on Earth with Blisk Spores, Natalya and Crypto infiltrated Tunguska to stop the KGB and crush Milenkov's plans. Shortly after arriving, Crypto and Natalya met up with agent Sergei to learn where to find Milenkov's plans. After a long and strenuous escape, Natalya enlisted Crypto's "services" in transporting the nuclear fuel rods being transported from the Frozen Lake to an unknown location. After discovering the secret radiation generators scattered around a strange tower, Crypto set about destroying them with the fuel rods. Shortly after, Pox and Crypto made a shocking discovery; the tower was actually a crashed Blisk warship, shot down during the Martian War and forced to land. After killing two Blisk warriors and a number of Mutants, Crypto is called upon by Pox to destroy the Blisk base and wipe out their presence on Earth. Natalya then sent Crypto to protect and interrogate Doctor Orlov, a former Project Solaris scientist, on what Project Solaris was and how to stop it. After retrieving Doctor Orlov's Blisk offensive based weapons datacore, Crypto left to save Natalya from being mutated at the remnants of the Blisk base. On cue, Milenkov arrived just after Crypto's "daring" rescue, to reveal his master plan to infect the whole planet Earth from the Blisk's true base on the Moon.
Science Town Science Town is the center of Tunguska, figuratively and almost literally. The town holds the only Nuclear power plant; where most of the scientists work at. Science Town is fenced-in, and outside the perimeters guarded by soldiers, suggesting that the Politburo consider it important. Science Town has also had a local food line, though it was shut down due to an assassination.
- Nuclear Plant The nuclear power plant in the center of Science Town. If one destroyed the Nuclear Plant, a domino effect of collapsing buildings would destroy half of Science Town, and creating radiation clouds around it.
Safehouse A hidden, fenced-in house in the naval of Tunguska, used by Agents Natalya Ivanova and Sergei as a base during the Furon-Soviet War.
Frozen Lake A town in northern Tunguska where a small number of scientists live. Frozen Lake has small cylindrical buildings, walled-in areas, and cabins scattered around. The Icebreaker and Doctor Orlov's hut are located in Frozen Lake. The name of the town is derived from a lake north of the town, where the Icebreaker docks.
- Icebreaker A ship docked in Frozen Lake that was used by the Soviets to carry nuclear fuel rods. During Crypto's visit to Tunguska, he and agent Sergei were tasked with collecting the fuel rods and transporting them to the safe house.
Tarkovskoye A town west of Frozen Lake. Unlike Frozen Lake, Science Town, Patrukhya, and Kimbaherskye, Tarkovskoye is in a state of constant warfare (similar to the Gouka Road in Takoshima). If Cypto goes there, he can watch (or participate in) a battle between Blisk Mutants, Soviet Soldiers, and civilians. The town could have either been a test site the KGB/Blisk used and hadn't informed the soldiers that the mutants were working for them or the Army could have been sent in as training practice, either for the Soviets or the Blisk. The Quantum Deconstructor Datacore can be found here.
- Tarkovskoye Forest A forest southwest of Tarkovskoye. The forest is usually empty, though during a string of "yeti" sightings it was the sight of a chaotic battle between armed civilians and Blisk mutants. A White Blisk, the so-called "yeti", was living near, and possibly commanding the mutants from, a cabin in the north of the forest. After Cryptosporidium killed the White Blisk the battle stopped for unknown reasons. Possibly because, the White Blisk had been creating spores to infect humans and make more mutants.
KGB Base The KGB's main base of operations. The base is fenced in and scattered with gun turrets, Soviet soldiers, and KGB agents. Only Officers, Soldiers, and KGB Agents are permitted access, while scientists and peasants are shot on sight. There is also a fenced-off area used for holding dissidents being executed. Cypto can observe soldiers executing peasants inside.
Blisk Base A Blisk Warship that crashed on Earth in 1908 causing the Tunguska event. The ship was later converted into base for the Blisk. After the Blisk were able to go to the moon, the base was no longer useful, and was played the role of a decoy more than an actual base. The base has three spires surrounding a smaller, central one, and is defended by many Blisk and Mutants. There is a simple anti-aircraft system, in the form of three Tesla-Coil like structures arranged around the base. The base was destroyed by Cryptosporidium 137, finishing off Blisk forces in Tunguska (with the exception of the mutants in Tarkovskoye).
- Blisk Base Generators Three generators on the northern, eastern, and southern sides of the Blisk Base that power the base's radiation emitters. They are located in tunnels cutting through the snowy slopes, and were destroyed by Cryptosporidium 137 with the nuclear fuel rods.
Patrukhya A very small village in southern Tunguska. The village only has two houses. It can be assumed that, other than Tarkovskoye, it is the only town where peasants live, although none can be found there.
Kimbaherskye A large village in southeastern Tunguska. The village is owned by the Russian Mafia. The area is guarded by Russian soldiers, who all appear to be armed male peasants.
- The Tunguska is a real-life river in Siberia, Russia, where the Tuguska event occurred in 1908 - a large meteoroid or comet hit Earth's atmosphere, causing a large air burst. In-game, the Tunguska event was a Blisk warship crashing on Earth.
- A fully-upgraded Meteor Strike can destroy Science Town's nuclear power plant in one blow while a non-upgraded Quantum Deconstructor requires two hits.
- According to Natalya, the male to female ratio in Tunguska is greatly in the male's favor. This makes it very easy for Natalya to gather information from the male scientist, soldiers, KGB agents, and peasants.
