8. Multi-planet carnage

Some people criticised Killzone 2's campaign for not being varied enough. That's not entirely fair. After the halfway point, the levels started to switch up, as did the relentless pace, and the scenery drastically changed. But the action was still confined to a single planet. In Killzone 3, we want the action to take us to multiple planets. We want the conflict to take in not only Earth and Helghan, but massive fleet space ships in between. Killzone was set on colony planet Vekta. Killzone 2 took the fight to the Helghast home planet, Helghan. In Killzone 3 we foresee a somewhat inevitable visit to Earth as humanity makes its final stand against the Helghast onslaught. But why limit it to such familiar territory? There's a whole galaxy to explore. It would provide an opportunity for Guerrilla to make Killzone 3 as varied a game as possible, while keeping that unmistakeable, gritty warfare experience Killzone 2 perfected.

7. A third faction

Well why not? The introduction of a third faction would certainly add spice to the ISA versus Helghast conflict, one that's raged for three games now. It's about time we saw something different, not only in terms of plot but also in terms of enemy type. The Helghast are great, don't get us wrong. We love them in fact. But a dramatic invasion from a mysterious force wouldn't rub us the wrong way. In fact, it gets us very excited indeed. Whose side are they on? What technology do they bring? What weapons have they got? What colour are their eyes? And here's another idea, just for fun. Why not make them playable? Ooooh.
