Metro 2033 was an "unpolished gem" for THQ which they "came to realise a little too late," but despite this it went on to sell over a million copies on PC alone. It's moved from "cult-hit" to "bonafide hit."
Now the developer is working on sequel Metro: Last Light, which continues Artyon's journey. Metro author Dmitry Glukhovsky had to provide a "completely new story and plotline" for the game.
A look back at 4A Games' admirably consistent post-apocalyptic shooter franchise.

The Metro video game series started with a humble b-list title, before building a strong fanbase and becoming a pioneer in the industry.

4A Games celebrates the 10th anniversary of its first-person shooter by offering it free for a week.
So, last metro game, should that be on my get cheap list?
I'd say thats a good thing.
I say that because, sure, the first game is based off the first book. But because the second game is not, it allows the author to create new and exiting ideas for the game and it might also tempt gamers to go and read the books, where they'll learn Metro 2034 book has a completely different story, so both media will keep gamers gripped. Its a win win :)
Well... it is if Metro 2034 was in english... :/ WHICH ITS NOT!!
nice!
