There's an E3 back-story trailer from Homefront on GameTrailers featuring live-action footage in a newsreel-style clip to tell the tale of the Korean aggression that drives the story in Homefront, the first-person shooter in development at KAOS Studios. There are also new previews of the game on 1UP, Joystiq, and Kotaku (thanks Joker961). The clip is embedded below.
