You are awakened by a noise. For many years now you have not seen any living beings. Grabbing your gun you quietly set out to see who else was in your house. Nothing's changed; you still have not seen the living. Monsters and mutants have tracked you. Now the main thing is to reach the hidden weapon. Fire it and stay alive.
