Homefront 1 isn't out yet, but Homefront 2 is already on the cards.
THQ's core games boss Danny Bilson said a sequel would be set on the other side of the Mississippi river.
"The sequel has new features and doesn't even deal with the same characters," Bilson revealed during an IGDA speech (reported by Joystiq).
"It takes place on the other side of the Mississippi - nobody knows what's going on over there because the North Koreans have irradiated the Mississippi with radioactive iodine and nobody can cross it without a hazmat suit. It's very interesting stuff."
Homefront is being aligned as THQ's big shooter series - its Call of Duty. Set in America's own back yard, the premise works around the "what if?" scenario of North Korea invading the home of the capitalist world.
It's not out until March 2011, but THQ has a book co-written by the Apocalypse Now screenwriter ready for early next year.
Homefront is in development for PC, PS3 and Xbox 360.
