Video game trailers can be crass, they can be dumb, and they can be misleading. They can also be pretty damned cool. This trailer for Metro: Last Light is pretty damned cool. It's called "The Mobious," and it takes a long, freeze-frame tour through a bunch of the sorts of scenes you'll see throughout the game's dank, sub-Moscow tunnels. You might be thinking it's peculiar for a trailer this involved and artful to come out well after a game is released, and you'd be right! Developer 4A explains how it came to be: The Mobius was created by Alexander Bereznyak, aka Monakh, who was originally employed by 4A as a capture artist. Soon it turned out that his talent was needed in the production team and he took over the role as lead technical artist. But over a couple of months, he continued to work alone on this trailer, that is now made public. Nice. Cool trailer, Mr. Bereznyak! (Cool game, too, as it happens.)
