We already know that Killzone 3 is going to be coming out in full 3D glory, but now we get to see what some of the action will be like in a teaser trailer released by the Sony PlayStation team.

In a previous interview James Callagher, content producer, SCEE told us that there would be "more enemy types, massive environments and a broader vision of the planet Helghan and its many terrains", and this teaser, which is like all good teasers, just that, shows us some of what the melee action will be like.

"First off we have a dark, stylish teaser trailer that highlights our new brutal melee combat system" says Sony.

The FPS, developed by Guerilla Games, also gets a bit of a platform feel thanks to the introduction of a jetpack "allowing you to soar high into the air and use the forward thrust twice before having to land, and opens up the possibilities for platforming and aerial combat",

Expect more info to come out at E3 where Pocket-lint will be bringing you all the latest action as it happens.
