The game exists in the universe of the novel Metro 2033 and its sequels, written by Russian author, Dmitry Glukhovsky, but does not follow any direct storylines from the books. Previously announced as Metro 2034,[5] the game is a sequel to the video game Metro 2033, and although Glukhovsky has apparently been working with the developers, it bears no relation to the book Metro 2034. Rumours on his website point to the upcoming book, Metro 2035, to be a novelisation of Metro: Last Light. Initially, the game was to be published under THQ and expected to be released in the middle of 2012; it was announced on February 2, 2012, that the game would be delayed until the first quarter of 2013, and on March 1, 2013 the game was delayed again until May

My God I have no words to describe how amazing this game was. Though through confusion I thought this was the first game when I began playing it but in the end it turned out it was the second game. Well anyway... I'll post about the first game when I'll get a chance to play it.
So, back to this game. Yes, it was amazing as hell. One of a kind.
Really great graphics, really good scenes, really awesome plot, thought out game style, amazing dialogues, nice and unexpected ending etc. etc. Everything was awesome about this game. Recommend it!
I have bought a book "Metro 2033", gonna read it eventually, later I'm planning on buying a book "Metro 2034".
