"You're not welcome here." That's the message Guerilla Games is trying to send to you all throughout Killzone 2, according to the various members of the team who speak in this second episode of the behind-the-scenes documentary. They discuss the world of Helghan, the ideology of its people and how that's reflected in the architecture. Check out the video after the break to hear it and to see some more in-game footage. It won't tide you over until the game's release this Friday, but it's a start.
