Well, isn't that surprising. The polish gaming magazine CD-Action got an exclusive deal to be the first in the world to review Killzone 3. Images are below the post (sorry for the quality, done with my cellphone). 
 
But in short, what did they say? (for those, who don't know polish and do not own the magazine) First - graphics, obviously. The reviewer was stunned of course and in his opinion, the other productions should not even be compared to this, even Killzone 2, which is still beatiful. The most praise goes to the jungle, which is reminescent of Avatar's vistas of Pandora, but the ice levels are also highly regarded. The dynamics of the enviroment and overall diversity during the playthrough (insane shootouts divided by some slower levels) is excellent and the game never becomes tedious or boring.
 
Next - the game is hard. Really hard. The reviewer, Enki is not a first timer, but his death count (edited, my mistake) was around 150 at  the end of a game (on normal difficulty!). This makes the circa 7-10h game longer, but is not a disatvantage, because game is not cheating in Call of Duty grenade spam style - Hellghasts are smart and our hero, Sev, is not an Iron Man, he dies after a second or two of concentrated fire. 
 
The next topic, multiplayer, is not reviewed in detail for obvious reasons - servers are still not publicly opened. But the reviewer played with pretty smart bots and multi is not a milestone, it's still good old Killzone 2 with great maps and some tweaks in playable classes. More details will be given after the grand premiere of the final game.
 
Another point, polish localisation (not so great, as always), is not important for most of us, even for me, cause I'll be playing this in english (thank god for a language selection)
 
The last points are about some cons, which are standard even in AAA games. One or two times, bodies get into textures, also, one or two times some High spawned from nowhere, but all in all, these are the mistakes found everywhere and they are so rare it's just a minor defect. For some, another drawback might be spawning our character after death under enemy fire, which results in another quick demise. But, as Enki, the reviewer says, Killzone is just hard and gamers have to learn to live with this.
 
The last photo below is the final rating: 9
Gamplay rated 9
Video 10 (well, duh. And the game was not yet tested in 3D)
audio 8 ( got one point off  because of the poor polish localisation I presume )  

pros: 
+one of the most beatiful games in the World, 
+great gameplay balance, diversity in the campaign, 
+high difficulty level (yes, that a pro for the reviewer), 
+good use of Move, especially with the sharpshooter (the reviewer even had a separate table to shortly say something about the gamplay with Move controller)
 
cons:
-The heroes are still flat as a wall
-minor bugs mentioned above

Shame about the small bugs but I'm still excited for it. Game looks beautiful and the multiplayer from 2 was fantastic.

sweet appreciate you taking the time to put this up for us, one question though, how come this polish mag got the exclusive? havent the killzone devs always been tight with the official playstation mag guys since they gave them major press leading up the release of the original Killzone. i remember reading the monthly preview of the first game and having it blow my mind. 

  I reeeally don't like CDA but they still seem to get most of the Polish exclusive deals/reviews.  It's kinda sad that they were an extremely anti-console and elistist PC only magazine, but then they just decided to start reviewing console games (I don't know the details though).

500 deaths in one play-through?  This might be the Super Meat Boy for first-person shooters!

" @Yoghurt: Nothing about the co op? "

What did he say about the game's mechanics contra those of Killzone 2's? 2's shitty cover system and boring level design made for really dull, lifeless battles, and additional difficulty is not enough to fix that.

Thanks for putting this up. The outlook ia indeed promising.

my only concern about KZ3 is if the controls have that deadzone that KZ2 had.  The "weighty feel" that people tried to justify as a good thing back when that second game was released.

I didn't have a big issue with the cover system in 2, once I got into a rhythm it felt pretty good, actually.

@kidman
As Imsh pointed out polish gamers are not excluding console gaming. but it's obvious we're not US and our gaming community has a long history of "pc only" fascism. I'm not counting Pegasus and other NES clones as a proper console:)

@Jayross I didn't feel any awkwardness in cover system

" my only concern about KZ3 is if the controls have that deadzone that KZ2 had.  The "weighty feel" that people tried to justify as a good thing back when that second game was released. "

 @Marz:
Personally, I've liked that "weight" to your moves. Some call it realistic, some call it a bug, but no matter how you name the effect, it was less arcady than CoD shooting. The only thing that bothered me was the default control scheme, but that's because of muscle memory coming from playing too much modern warfare before KZ2. And the issue of "strange" controls is nonexistent when you can set them any way you want, even with run under R2 and shooting with X.

"I really hope this is wrong or the reviewer really does suck because 500 deaths in one playthrough sounds really annoying especially if the checkpoints are like they were in the first game.  edit. "first game" I somehow managed to  ignore kz1's existance. "

" @Icemael: Mechanics from KZ2 are still there, cover system is used extensively (because your character dies so easily) and improvement lies in variety of levels - the shoot shoot shoot playstyle of KZ2 is gone, Guerilla thought of a lot more imaginative ways to handle Highs. "

So your saying that Sev and Rico are still in it and the controls still suck?  Ok, no sell.
