Just how excited are you about seeing actual game footage of the yet to be released Killzone 3?

If the answer is very, then you'll be over the moon that Sony has just released a gameplay trailer ahead of its press conference at E3 in Los Angeles.

"Today we’re proud to present the first gameplay trailer for Killzone 3. What you are about to see is a trailer made completely out of in-game footage, taken from the game’s fourth mission, called Frozen Shores", says Sony in a blog post touting the new trailer.

If you weren't already aware, Killzone 3 will take you to dangerous new corners of the Helghast home planet, and reveal that its environments are far more diverse than ISA Command had previously believed.
