Metro 2033.

The subway is filled not only with people but also with hungry mutant monsters who are trying to get into this last place for human life in order to kill and eat. A nuclear explosion occurred in 2013, 20 years ago. Sometimes, monsters still break through gates and roadblocks, attacking citizens who are trying to defend themselves with seasoned Soviet machine guns. And bullets from these machine guns are the main currency of this metro. With them and their quantity you can buy everything you can. Machine guns, horns, passports, girls, trinkets and the like. People in the subway eat pigs, which were able to pass through the gates once and reproduce them, or mushrooms, which grow in a specially designated place and do not require sunlight. Sunlight is also an enemy. After 20 years without lighting, your eyes are not accustomed to such light and you can easily go blind if you go out during daylight hours.

Place of appearance: botanical garden station. The most terrible place for the inhabitants. From the surface, where the botanical garden itself once stood, terrible mutants are coming, ready to eat anyone who gets in the way. Their main strength: psychological interaction. People go crazy and kill others and themselves. The station is filled with military tents in which people spend the night. There is an emergency clock on the wall showing the time. In the corner there is a corridor that leads to a farm with mushrooms and pigs. In the middle of the station, there is a fire with soldiers drinking tea from the same mushrooms. The station has rails in two directions. One leads deep into the bridges, the other to the neighboring station, filled with people.

On the surface everything is worse than in the subway. Abandoned low-rise buildings that have been taken over by mutational nature. Remnants of life and the burnt-out faces of people who didn’t have time... However, in addition to mutants and radiation, you can find a lot of supplies, the main thing is to bring them home and not die yourself.
