In Killzone: Shadow Fall for the PS4, Helghast and Vektans live in a divided city and there are two sides to every conflict. Find out more in this quick story trailer that helps set up the game.

The game debuted at last week's PlayStation 4 reveal, and now developer Guerilla Games has released this new footage of the PS4 launch title (coming sometime this holiday season). At the time of Shadow Fall's reveal, Herman Hulst, Guerilla managing director, said: "The story draws parallels to Cold War Berlin, with two factions living side by side divided by a vast wall. This is a story about the loss of home, the search of new home, and the lengths to which people go to defend it."
