The gray/brown filter isn't there anymore so colors look more natural. Some visual issues in the build we saw in November (like the one guy's face and how it didn't look natural) has been fixed. The fire trail on the shot down landing craft has been made better again and look more badass. It looks like an extra light on one of the landing craft. The explosion of the one landing craft has been changed and now it looks like it was hit by lightning instead of an explosion.

Also, if you see the video, the voices have been changed from the placeholders we saw in November and December. Rico's voice, while still a little overdone, isn't as bad as it was previously and the dialog lines are said when they are supposed to be said (if you remember, the "where are the other guy's" line didn't even play in the previous build).

Check out the HD version for a much better view of it.

Though BEWARE, the person playing sucks.

Thanks for the pro tip, it looks like most of the visual improvement are overhaul on specific objects (other than the colour filter).

I have not watched ANY video of the single player game at this point (and don't intend to), I am trying to avoid all spoilers prior to expriencing this game. :)

I think it's clear from the improved clarity in the very first frame comparison that Killzone 2 has finally gone through puberty, because there is obviously more facial hair and the ability to grow a full beard in the new version.

Look at the difference from E3 2007 - December 2008 - January 2009

The removal of the gray/brown filter brings out the colors, lights, and details more. Check it out.

Awesomeness

lol were still a month away till it's release I wonder how much it'll improve by then

As much as I hated Killzone 1, the sequel might just be worthwhile.

i didn't mind KZ1 but I didn't think that it was great but from what i have seen from KZ2 i am very exited to see the final game
