James Gallagher - SCEE Content Producer has posted on the PlayStation EU blog about a recent unveiling of Killzone 3 by Hermen Hulst, Managing Director of Guerrilla Games

"The level playable at the show was set in an arctic environment and introduced a number of new gameplay elements. One of the most eye-catching is the new jet packs: first you must fight off three Jetpack Troopers, who are quick and heavily armed. Once you defeat them, you discover a spare jetpack that you can strap yourself into. It works like an exaggerated jump, allowing you to soar high into the air and use the forward thrust twice before having to land, and opens up the possibilities for platforming and aerial combat."

"If you remember, the Jetpack Troopers were in Killzone Liberation on PSP and we've always wanted to bring them back," explained Hermen. "When you include aerial combat you obviously need plenty of space so the much bigger levels in Killzone 3 have presented us with the opportunity to include this enemy."
