My name is Denis Demidov and I survived the end of the world... After the start of the war, I decided that I needed to build a bunker and I was right. Half a year later, all hell broke loose and I hid in a shelter. For another six months the conflict only escalated, but I was safe. At least physically. After six months of stress and isolation, my psyche became unsettled. According to all the symptoms, I developed schizophrenia and a second personality appeared...Ku-ku! Here I am! Don't listen to this bore. War, blah blah, who cares? The coolest thing is that the System came to our world and a real fucking apocalypse began! That's where the fun is, oh-oh yeah-ah. Now you can do whatever you want, collect loot, grope girls' asses, knock off mutants' heads, level up. Although I don’t give a damn about these numbers, the main thing is that it will be fun! But not everyone will survive, gee-gee. Hey, Demidov, I'm not yet... Ahem, I apologize for this misunderstanding. Make yourself comfortable. Now I’ll tell you everything in detail and in order.
