Players will be resuming their fight on Helghan in Killzone 3, even though it was kind-of mission accomplished at the end of Killzone 2. You killed Visari, which was the greater mission, but now there's a vie for power up for grabs. Political turmoil is never a pretty thing and the last thing you want to be is involved in it, but that's where Sev and Rico find themselves at the onset of the game.
A more descriptive version of the story comes from Killzone 3's managing director, Herman Hulst:
"We recognize how important the story is in Killzone games. And we’re making great leaps forward with character development and the quality of the dialogue and the writing. We’re going all-out to make Killzone 3 a rounded experience on all fronts.
So with Visari gone, there’s a power vacuum on Helghan where figures like Stahl, the head of the Helghan weapon producer, are vying for power. Essentially, the surviving ISA soldiers are caught in the middle of a catfight when what they really need is to get the hell off the planet and return to Vekta.
On the ground, this political situation changes the nature of the conflict. The Helghan are now in the ascendancy and they are bringing a great deal of new technology to the fray. The result for the player is that you’ll be encountering new weapons and enemy types with their own distinct behavior."
Guerrilla Games hosted an event in Amsterdam showcasing a level in the game, as well as the out-of-the-box 3D support. The level showcased was the fourth in the game and depicted our heroes in a snow filled area of Helghan where they must rescue Captain Narville, a NPC from the previous title. As you can see above, the Helghast have access to some jetpacks now (which were present in Killzone: Liberation) and are a bit more difficult to take down when they're flying through the air and shooting at you with a minigun. Don't you worry though, Sev gets access to a jetpack and can rain death-from-above as well.
Problems like closed areas and "corridor shooting" have been eliminated with this offering in the franchise, as Hulst describes the level design:
"The response to Killzone 2 has been fantastic but there is a general response that it had too many ‘corridors’. We have to temper that with the knowledge that many players really enjoy that gameplay style. Our plan is to solve this dilemma with huge variation in gameplay styles.
We had plenty of variety in Killzone 2 but much of it was introduced in the second half of the game. This time around, right from the start every new level has its own distinct feel."
And as you can tell from the screens, the color palette has increased quite a bit as well, and has expanded from the browns and blacks that were so prevalent in Killzone 2. Combat has been given a change from the first person cover shooting that resulted in fast death if you weren't smart into more direct fire-fights. Something that was revamped completely and given a bigger role is the "Brutal Melee" system, a context-sensitive system that will reward players with unique kill animations.
Of course, Killzone 3's multiplayer will be just a big as part of the game as the single player. Hulst refers to the multiplayer as "the other half of the game", so it's very fair to say that the same kind of care will be going into making the online just as good as the single player. No details have emerged for it, though.
In terms of the stereoscopic 3D support, the game will be supporting it, but you will need glasses and a special kind of TV that will display it.
I had a lot of fun with Killzone 2 and I don't think Killzone 3 will be any different, if not better. There is going to be a huge debate involving Crysis 2, regarding which game looks better, and personally, until I get to play both games on great TVs and bad TVs, I will reserve a judgment.
Killzone 3 has no release date as of yet, but will be shipping exclusively for PS3.
