In related news, IncGamers has a Clear Sky interview with GSG Game World's Oleg Yavorsky:

How is The Zone in Clear Sky different from that in SOC? How do these differences affect gameplay?

Some aspects of the gameplay were changed very much. For example artifact search. In Clear Sky some anomalies are completely invisible and the artifacts in them also. You need to use some sort of detector to find a safe route inside the anomaly fields and got the artifact. So a two handed HUD was added when you carry a detector in one hand and a bolt or one-handed weapon in another. At this time negative powers of anomaly field affects you and you are a good target for enemy stalkers, so you will need good protective suits and equipment for that.

We added the possibility of upgrading weapons so you could improve the weapon you like in many characteristics like accuracy, distance, magazine capacity etc. You can also repair your weapon and protective suit.

Wait a sec. Isn't the release date the 15th for this?

Not the European release. It wasn't delayed.

Ah, I didn't know that.

I see on gamespot that most of the reviews are from UK magazines, too.

Dang, I really need to get around to finishing the original…
