Well, here's a surreal moment that's been a long time coming. Almost three years to the day since GamesRadar first saw the infamous "is it real or not?" Killzone 2 trailer at E3 2005, they have just seen the scene - heavily reworked, but nonetheless unmistakable - live and in real time in its proper place in the game.
As it turns out, it's the opening scene to the game's second level, Corinth River. Humanity is attacking the evil Helghast homeworld in an effort to kill Visari (think Space Hitler). So, after a quick tutorial on level one's capital ship, it's time for your character Sev to jump into a fleet of small, open-roofed flying troop transports called Intruders - with Rico from the previous Killzone games - and drop into the hot zone.
