Sony announced a Killzone 3 single player demo slated for February 9th for PlayStation Plus members. If you don't have a PlayStation Plus account, don't worry. You'll still be able to get the demo a week later, on February 16th. Killzone 3's story follows Sev, a Special Forces operative, as he tries to stop a Helghast invasion on Earth. The demo will put players in the "Icy Incursion" level of the campaign, featuring a frigid Helghan area that allows players to take flight via jetpack in order to complete the mission.
The demo will be available in both 2D and 3D. The 2D version will be able to utilize the splitscreen co-op feature, something not yet available for the 3D players. The Killzone 3 demo will also include PlayStation Move capabilities, so if you want to really immerse yourself in the action and feel like you're actually punching and shooting those evil Helghans, you're all set.
