So every now and then we get some information on a new game, Metro: Last Light is one of those games. Metro: Last Light is a follow to the Cult Favorite Metro 2033. This game takes place underneath a post-apocalyptic Moscow. I mean just look at the trailer.
The game itself is scheduled for release in early 2013, so assuming the Mayans are wrong you should stay tuned into Team Fighting Mongoose for more exclusive Metro: Last Light content.
