I thought Killzone 3 should have been from the Helghast perspective since Killzone 2 showed that the ISA have no claim over the "Good guys" throne in that series. Turns out Guerrilla Games did that by accident, and used Killzone 3 as an effort to rectify that by showing how "evil" the Helghast were supposed to be. So they went from an army of people who were abandoned to a harsh planet into an evil army that creates exploding spiders and plan to nuke Earth for no reason other than to be evil.
What I found to be an interesting dynamic of sympathetic antagonists and powerful, greedy protagonists got replaced by the story they intended, which unfortunately seems to be "evil invaders started a war, kill them."
I have to agree. I don't own a ps3, but I played Killzone 2 on my friends. I felt like I was truly in Sev's shoes, and felt the same sense of cynicism against the ISA and the whole war that seemed more and more useless as it dragged on. After what Rico did, I honestly questioned whether it was the good campaign or not. Based on what you've said, it seems this moving, even revealing, campaign design was an unintended fluke. Great job guerilla games...
