New Teaser Trailer for Killzone 3

Sony has released the first trailer for Killzone 3, and it's pretty explosive. Okay, so there's only one explosion, but still. The trailer features an intense hand-to-hand fight between Sev and a Helghast soldier which ends with Sev taking the Helghast's mask and putting it on. Guessing we'll be seeing some intense new melee combat and maybe some undercover stuff? Hopefully they'll show off some of that melee in-game with the demo coming up on Spike next Friday.
