Killzone 3's senior producer Steven Ter Heide has said the story this time around has been "considerably ramped up" when comparing KZ3 to the other entries in the series.
Speaking with D'toid, Ter Heide even touched a bit on the civil war going in with the Helghast.
"The thing about Killzone’s storyline is that while it always takes a backseat to the action, you can learn a lot about its universe by carefully reading between the lines," said Ter Heide. "When you listen to all the bits of Helghast dialogue in the previous game, for instance, it’s clear that they don’t consider themselves villains at all. From their perspective it’s the ISA pursuing the aggressive imperialist policy; they’re just defending Helghast interests.
"That said, we’ve considerably ramped up the pace of the story for Killzone 3. We will show more of the Helghast side, their motivations and background. With Visari out of the picture, several potential successors are vying for control of the Helghast Council. Meanwhile, the remnants of the ISA invasion force want to get off the planet before their window of opportunity closes. These story arcs converge for an explosive finale."
Guerrilla boss Herman Hulst said previously the team was "weaving a story that has more shades of gray than the trite representation of ‘good vs. evil", and that the Helghast still has some "humanity left in them".
We'll see come February, through either the standard edition or the Helghast edition.
