Punchy promotional trailers filmed with live actors are becoming an increasingly popular marketing tool among games publishers, and as THQ's Metro: Last Light rep shared with us recently, their impressive live action effort really helped "put the IP very much on the map", beyond it's pre-existing audience of fans from the first game and the Metro novels.
