S.T.A.L.K.E.R.: Clear Sky - GC: 2007 Preview @ IGN

IGN takes a look at the demo presented at GC 2007 to see what's changed since E3 in the S.T.A.L.K.E.R. prequel. As usual these days there's a strong emphasis on graphics, but they also examine some game design and AI details, including where to spend your in-game cash:

 ...The Ai knows when to rush and when to sneak, when to hide and when to break cover.We saw the AI using cover very effectively in the first firefight. When you see your friendly units and the enemy units doing it together as they shoot it out, you'll really feel like you've dropped down into the midst of a battle...

...The team has also changed a few world design elements. Now, for example, you actually have something to spend all those thosands of rubles on. There are now places where you can buy guns, weapon upgrades and repairs, and even new suits. Having a chance to take a bit more of a commercial approach to your gear will definitely give you a bit more flexibility.
