Sony and Guerrilla Games have updated the official Killzone 3 website with a short teaser trailer for the game -- one which places a heavy focus on the "brutal melee system" we were introduced to during our preview last week. Check out the trailer above, and watch as series protagonist Sev applies tremendous amounts of force to Helghast troopers using his feet, elbows, knees and rifle. We can't help but marvel at the structurally questionable pile of pummeled dudes he's built. Seriously, that must have taken a while.

It's a pretty stylish trailer, though the ending just leaves us confused. Why would he don one of the Helghast's iconic, glowy-eyed helmets? It cannot smell good in there.
