We don't often see trailers released after a game comes out, not unless it's a trailer for DLC or some such. The case of Metro: Last Light and today's release, however, is a bit different. Dubbed "Mobius," the new trailer is actually a creative piece by Alexander Bereznyak.
Bereznyak, or "Monakh," as he is also known, is a fellow originally employed by 4A Games as a capture artist. He later devoted his time to Metro: Last Light as lead technical artist for the production team, but continued to work on this video. Today, 4A made it available to the public, and it's some video. By that, I mean you really should watch it. It's pretty chilling, telling a story of a settlement fighting for survival -- without any sort of dialogue, mind you. All in all, a pretty accurate portrait of life in the Metro.
Seriously, even if you haven't played Metro, give this video a look-see. All of it. Don't cheat and skip ahead, now.
