GamesRadar: What audience are you trying to reach with these ads, especially considering they don't show actual gameplay?
Frank: Although we didn't make the ad, we understand that it's designed to grab the viewers' attention and make them feel emotionally involved with the Marines in our game, by humanizing them and giving them a future, as well as a past. In that sense, the ads are for everyone.
GamesRadar: Finally, can you tell us more about the impressive diorama? Who made it, how big is it, where is it now, where will it end up, can fans ever hope to see it for themselves?
Frank: The diorama is about 1200 square feet, the work of New Deal Studios and Stan Winston's studio and there will be more news on where and when it can be seen very soon.
