How can it not be that?

Yeah... maybe you are right after all. I mean, look at Perfect Dark, one of the best looking N64 games. It even had 4 player split-screen!

Now I'd really like to know the reason why Guerilla didn't implement co-op and split-screen! D:

Seb Downie has always stressed that there's no plan for splitscreen DLC at the moment. It simply isn't something they can do before launch, as it'd take so much time and manpower that either other aspects of the game would suffer, or else the game would have to be delayed.

GG are great at listening to their fans, though, and if enough people request splitscreen after launch (and I'm sure many will), I have no doubt that GG will add it in if they can via a patch at some point.

I don't understand people that are with "no coop is no purchase from me". If a game is good (IF, not saying that it'll definitely will be), then why leave it? :-/

If GoW2 didn't have co-op, would you have left it hanging? A good game is a good game. A good single + multiplayer game surely is worth at least as much as a game with a crappy co-op and such? :-/

@ twesterm: shouldn't it be possible to make a separate campaign for co-op (like R2 has)? They could offer that one afterwards, no?

didn't Killone 1 at least have Splitscreen

I'm still hyped,no matter the lack of coop and splitscreen (quite obvious if there's not coop play).
The best thing about Killzone 2 is the multiplayer online mode and must be a glorious hell of a campaign,enough for me.

They've just lost me as a potential buyer. I was disappointed with there being no co-op story mode in Resistance 2 but was more than satisfied with the splitscreen co-op/competitive online modes. But this is an absolute deal breaker for me in any shooter.

Personally I like co-op very much; though it's sometimes taken into wrong direction these days. Anyway, the lack of co-op is a pity but it's probably not a very important feature in this case (it usually isn't).

Killzone 2 doesn't seem to have anything revolutionary but it's one of the games I'm looking forward to. It's kinda pretty and its multiplayer is class-based, and I like class-based games. Well, at least I like Enemy Territory (and not Battlefield and only maybe, and even then only a little, Team Fortress 2) :P In any case, Killzone 2 might be something I'm getting. I guess I'll wait for the reviews first, though, as I want an unbiased opinion (well, rather a description as reviews aren't to be trusted very much but reviews offer a description).

Cool, I'm really eager to see what will be changed and made better from the beta to the final build. Great that people with 1080i TV's wont get screwed over.

As far as co-op and split screen is concerned, it's not a deal breaker for me so I don't really care. I like to have the whole screen as opposed to squinting at half or even less of the screen.

yea no co-op is gonna hurt alot of people.. didnt they claim going to have 4player split screen co-op? sucksss

What if that part of the game sucks?    A game with a good singleplayer and a good multiplayer > a game with a good singleplayer, a gimped co-op and a good multiplayer.
