Homefront: The Revolution is the second game to come out in the Homefront series. Dambuster has stated this is not a sequel to the original Homefront, hence why we see no 2 on the artwork. Homefront: The Revolution is taking place 2 years after the original Homefront and four years into the invasion of the United States by the Greater Korean Republic.
Slated for a 2016 release and with Dambuster wanting to leave it's own stamp on the series. Homefront The Revolution might be decent.
Homefront The Revolution is going to be released in 2016 for Linux, Microsoft Windows, OS X, PlayStation 4, and Xbox One.
