"America Has Fallen" is the title of this trailer from Homefront: The Revolution, which is the opening cinematic from the upcoming insurgency shooter sequel. Deep Silver also offers another new trailer called "APEX and the Technology of Control" with more of the game's back story. Here's word on the scene this sets:

A reimagined alternate history dating back to ashes of the Korean War documents the fall of one global superpower and the rise of another, driven by the ruthless APEX Corporation in a world with chilling parallels to our own.

"The core premise of Homefront - an occupation on American soil - remains unchanged," said Hasit Zala, Game Director at Dambuster Studios. "But we have created a brand new fiction that offers a very different interpretation of how we got there."
