The K.O.N.T.U.R. research base is divided into residential blocks, a dining hall, security posts, underground tunnels, hangars for research on evil spirits and mimics, laboratories for scientists, isolation wards for experiments on volunteers, and barracks for soldiers.
Communication between all buildings and people is ensured by radio. Many of the buildings are very far from each other, and K.O.N.T.U.R. employees travel by metro from different sectors.

The Metro, or Moscow Subway, is an excellent defense for the K.O.N.T.U.R. base.
Trains transport employees to the base at night. Kilometers of deep underground tunnels ensure secrecy and security. The K.O.N.T.U.R. base is located 20 meters below the deepest metro station in Moscow. During the day, the entrance to the base is strictly closed and guarded.

Viruses are mutated cells or unidentified liquids, sometimes gases. Viruses have a wide range of effects on people, including making them stronger, more resilient, more aggressive, more passive, putting them to sleep, causing them to levitate, altering their body structure, and even destroying their bodies completely. Viruses are often tested on volunteers. Scientists study viruses and conduct a wide variety of experiments with them.

Undead creatures are various creatures and monsters from another world. These creatures emerge from the void and darkness. Often, undead creatures mimic or copy ordinary objects, such as furniture, children's toys, or electronics. They are extremely dangerous and unpredictable. Scientists study them or issue orders for their destruction. Undead creatures are easily destroyed by flamethrowers and explosive bullets.

Many paranormal phenomena occur in the USSR, and the K.O.N.T.U.R. organization is studying them in detail. Examples of paranormal phenomena include: "black goo" – the appearance of large black bubbling puddles with an unknown effect; "unstable point" – an invisible point the size of a door, which acts as a portal to a random location on the planet and beyond; "flickering" – flickering lights causing electronics to malfunction and power outages; the effect on humans is unknown; "streams of blood" – blood appearing from nowhere, streaming across the floor and walls, potentially infectious and dangerous.
There are many other paranormal phenomena and scientists give them different code names and then study them.

Volunteers are ordinary people or criminals who agree to participate in self-experimentation and various scientific tests. These experiments are often dangerous, typically involving viral tolerance tests, contact with paranormal points, unstable objects from another world, and prolonged isolation in sealed living quarters at the K.O.N.T.U.R. facility. Volunteers are men and women of any age. The mortality rate is high. The average number of volunteers at the facility is 30, but it can be higher.

Workers are the personnel who maintain the K.O.N.T.U.R. base underground. They clean tunnels, hangars, laboratories, and technical rooms. They have to deal with viruses, unidentified secretions, unruly test subjects, monsters and ghosts, as well as paranormal phenomena. All workers wear strictly hazmat suits and gas masks. The average age of workers is between 18 and 26. This position is one of the most dangerous at the facility. The total number of workers is approximately 80.

Scientists at the K.O.N.T.U.R. organization are the best minds in the USSR, studying monsters, ghosts, viruses, and paranormal phenomena. The scientists include both men and women, ranging in age from 24 to 40. They wear white coats, medical masks, and gloves. They often interact with test subjects. They conduct a wide variety of experiments on test subjects and monsters. Scientists often give orders to destroy monsters and the undead.

The complex's security is staffed by employees of the institutes or the Moscow Metro. The guards are both men and women, ranging in age from 18 to 24. They wear dark blue uniforms and carry batons. The security team numbers approximately 35 people.

Soviet soldiers vigilantly guard the secret K.O.N.T.U.R. complex. Armed with rifles and dressed in standard military uniform, they number approximately 50.

K.O.N.T.U.R., or Control of Objects of Unknown Type of Conditional Reality, is a secret government agency tasked with combating viruses, zombies, mimics, and paranormal phenomena. K.O.N.T.U.R. was founded in the USSR in 1977 and remains active to this day. The organization employs scientists, soldiers, security guards, metro personnel, engineers, and volunteers. The organization is top secret, and its base is located beneath the Moscow Metro tunnels, deep underground. All K.O.N.T.U.R. employees are transported to the base at night via metro stations, using trains. The K.O.N.T.U.R. base utilizes the latest Soviet military technology and is a complex technological labyrinth consisting of laboratories, test subject rooms, and hangars for evil spirits, mimics, and dangerous creatures. Most of the base's corridors are patrolled by guards or soldiers. Scientists work in the laboratories, conducting experiments on volunteer test subjects. Engineers create traps for evil spirits and monsters. Cleaners and workers maintain the premises and ensure the stability of the tests. Most personnel wear hazmat suits and gas masks to avoid contamination. Soldiers and guards are armed with batons and rifles. Volunteers for testing are recruited from ordinary citizens and criminals. The K.O.N.T.U.R. base has test hangars, personnel quarters, security booths, and archive libraries. All experiments are recorded by video cameras and documented in writing, which are then archived.
