Sheol - The Ultimate Shelter

Tensions between the superpowers increased to the point that someone finally pressed a large red button and nuclear warheads flew towards the US, Russia and China. You, as ordinary residents, heard only the sound of alarm sirens and the message "Attention! Everyone to the shelter!". So you went to the nearest shelter and, there, you expected the coming of safer times for several years. You pass years in underground lethargy, and the systems in your shelter are becoming more and more vulnerable. Spare parts end up in a flash, and you only think about the worst. The only hope is for you to escape from the sinking ship and go to "Sheol - the Last Shelter", which you have heard from time to time in radio transmissions underground. So you collect all the equipment, put on the anti-radiation coveralls and go to the surface - in search of the mythical Sheol. A place that will allow you to become a new, wonderful world.
