THQ officially announces Metro: Last Light, the previously revealed upcoming sequel to Metro 2033, the futuristic first-person shooter. The Metro: Last Light Announcement Trailer offers a look at the game using very rapid cuts and concept art, all set to the tune of Machine Gun by Portishead. There are also some new screenshots on the Metro Facebook Page, and here's a bit from the announcement, which says the game is due this year:

Metro: Last Light will immerse the player in the haunting, desolate ruins of post-apocalyptic Moscow, one of the most richly detailed, and beautifully realised gaming worlds of modern times. Developer 4A Games will deliver a terrifying, atmospheric single-player adventure that fuses thrilling combat with exploration and survival horror to create a unique, memorable experience.
