The Killzone games have always straddled a curiously foggy moral line. Although made out to be aggressors, the Helghast are, in many instances, simply defending their homeland from foreign invaders€”most notably us, the player. In any case, relations between the two sides steadily break down over the first three games (and see no revitalization in Killzone: Shadow Fall), and fighting eventually escalates to a nuclear level. More thoughtful war shooters like Spec Ops: The Line would roll their eyes at the notion, but blowing things up has worked in the past so that's where the home team hedges its bets. Killzone 3 ends with a nuclear strike against the Helghast... executed with all the suspense and tension of trying to a win a teddy bear from an arcade crane. It comes out of nowhere, ends with a flash (no pun intended), and is paired with what may be the most uninspired one-liner in action history: "I wonder how many people we just killed?" Really tugs at the heart strings, doesn't it?
