PushSquare: "Somewhat souring my experience with Killzone 2 was the admittedly weak narrative running throughout the entire single-player campaign. If you've played the game, like myself, you probably harbour an underground loathing for Rico that occasionally forces you bolt upright covered in a cold sweat during deep sleeps. The only redeeming factors Killzone 2 has as a story come from the "antagonists", the Helghast, a mysterious race whom we're assumed to hate but never quite told why. It's no wonder; my research concludes that they're the bloody good guys!
A friend of mine recently put me on the trail of the Killzone 2 backstory. Not only was I blown away that Sony's biggest shooter actually had a deep history, I was actually dumbfounded as to why Guerilla opted not to use any of it. The plot is good and it's a shame Guerilla didn't put more into it. The glorious technical feats achieved in Killzone 2 could have been seriously underlined if they'd been given more context. Like the war itself; I just assumed the Helghast were rotten aliens trying to take over the world. I never once questioned the motives behind my foul-mouthed team. I guess that's for the best given that the ISA are rotten, raging hypocrites.
According to Guerilla's story, the Helghast aren't bad guys at all."
