Killzone 3. The Jetpacks. The Brutal Melee. The PlayStation Move. The 3D!

Ever wanted to get your hands on the action? Killzone 3 may not be out until 02.22.11, but we’re giving you a chance to hop into the “Icy Incursion” level that takes place halfway through the campaign.

February 15th is the day that Killzone 3’s Single Player demo hits the PlayStation Store.

PlayStation Plus members will be able to download the demo on February 8th!

Strap on that jetpack and take flight through the arctic environments of Helghan.

There will be two separate downloads available from the PlayStation Store: one in 2D and one in 3D. Both versions will take place on the “Icy Incursion” level. Don’t worry – downloading the 3D version and playing it on your 2D TV won’t break anything … you’ll just see a message saying “No 3D TV detected.” The 2D version has splitscreen coop as well, a feature not available in the 3D demo.

All PlayStation Plus subscribers who have automatic downloads enabled will receive the 2D single player demo of Guerrilla Games’ upcoming blockbuster. As a reminder, PlayStation Plus subscribers can turn on the Automatic Download feature under “System Settings” on the XMB. This feature will update your PS3 with firmware updates, patches to recently played games and other select videos or game demos.

These demos will be PlayStation Move enabled, giving gamers a chance to experience Killzone 3 with the most immersive controls. When you get your hands on the demo, be sure to try out one of my favorite new mechanics, the Brutal Melee attacks! Get close to your enemy and hit the melee button (or thrust your PlayStation Move motion controller at the screen).

The aiming and movement mechanics have been tightened since Killzone 2. Play around with it and let us know what you think!

Stay tuned to the blog as we give out more details on the upcoming multiplayer Open Beta. While you wait, bone up with this full list of weapons to get a day-one edge.
