New footage of a developer demo for Killzone 2 showcases, in addition to the very grey but attractive graphics, the ‘Lean and Peek’ cover mechanic. Essentially it works like the cover system in games like Rainbow Six Vegas or Gears of War, but doesn’t compromise the first-person perspective to do so. It maps the left shoulder button to the cover snap (like hitting ‘A’ in Gears) but pulls low cover up to cover about half the screen and still allows for blind fire as well as snap-up firing. With high cover you use the analog stick to lean out and take your shots. Check out the video above for the full scoop.
