The narrative backstory for the videogame Homefront is the focus of the game's debut trailer, which includes no graphics or imagery from the game at all, instead describing an alternate future in which North Korea has successfully invaded the United States after disabling the global communications network by detonating a nuclear device in space. The trailer ingeniously interweaves motion graphics and fabricated video and still images with real news footage, including an opening press statement by Secretary of State Hilary Clinton. The alternate history or alternate universe trope is not uncommon as part of the narrative backstory of commercial video games, but this trailer has an unusual focus on this aspect of the game, perhaps because the game's narrative was written by Hollywood screenwriter, John Milius, known for his work on such films as Apocalypse Now and Red Dawn.
