Chernobyl

In 1986, an accident occurred at the Chernobyl nuclear power plant in the fourth power unit... After that, strange things started happening in the zone, people were disappearing. The city became a ghost. The surviving residents created entire underground cities with their own authority, laws, and even currency. Safety was only found in the bunkers and mines underground. Radiation was on the surface. The people who remained there were no longer the same as before. Survival is very difficult: resources are decreasing, and every exit outside can be the last, as the city is teeming with mutants. You received a signal from sector A that it has been destroyed and people who survived need help. You need to find an antidote in the bunker that will help stop the infection, and then get out of there quickly, otherwise, you will be left with creatures locked in from the inside.
