THQ have just announced "Homefront", a first-person shooter that tells the story of a United States humbled by total economic collapse, then conquered by North Korea. So not based on a true story, then.
Interestingly, the game has been written by John Milius, a Hollywood screenwriter (and total gun nut) who has worked on Dirty Harry, Apocalypse Now, Conan and, yes, Red Dawn.
Which is funny, because Homefront's story doesn't stray too far from that of Red Dawn, with players joining the "American Civil Resistance" as they fight to overthrow their Communist oppressors. Who are from... North Korea.
The game is being developed by Kaos Studios, the team behind Frontlines: Fuel of War, and is due for the 360, PS3 & PC. More details, as well as something to look at (come on THQ, at least one screen would have been nice), will be provided during E3.
