The 'Welcome to Moscow' video reveals what was shown behind closed doors to attendees at E3 2012 last month.
It sees two soldiers form an alliance to cross the hostile surface of Moscow, in an attempt to reach safety in a station named 'The Theatre'.
Announced last year, Metro: Last Light is a sequel to Metro 2033. Unlike the books it has its own original story, but has the blessing of series author Dmitry Glukhovsky.
The follow-up will see the return of the original's bullet currency system.
It has also been confirmed that Metro: Last Light is no longer a Wii U title.
Metro: Last Light will be available on Xbox 360, PS3 and PC in 2013.
