A Killzone 3 single player demo will be available for PS3 owners early next month. PlayStation Plus members can get their hands on the demo February 8th, while non Plus members will have to wait until February 15th.
The demo will give players a look at the “Icy Incursion” level, which takes place half way through the main campaign. It will be available it 2D and 3D, but the 2D version will include split-screen coop. Both versions of the demo will be PlayStation Move enabled.
Sony says that they will have more information soon on the already announced multiplayer open beta.
