I have started reading Metro 2033, the book which came before the game. I liked this little quip about the ‘underground party.’

Comrade Moskvin, general secretary of the Communist Party of the Moscow Underground, proved dialectically the possibility of constructing socialism in one metro line.

Heh heh, socialism in one country metro line.

I forgot how scary the story is. I read it last night, with all the lights turned off and the windows open. I had to turn the lights on to avoid having nightmares.
