This near-future take on the Red Dawn premise - yes, Kaos even tapped that movie's writer for this project - has a prequel novel (http://www.amazon.com/Homefront-Voice-Freedom-John-Milius/dp/0345527151/ref=sr_1_1?s=books&ie=UTF8&qid=1299129433&sr=1-1)... and a soundtrack (http://www.sumthing.com/itemDetails.aspx?id=5256). Oddly, the fact of its being released next week seems to have not been widely exposed (you'll find no mention of it on the ofifcial website proper, but a search of the forum did turn up this thread (http://community.homefront-game.com/forums/topic/2222)).
