STALKER: Shadow of Chernobyl - hands-on

Unlike most FPS games, there's an ecology with the AI that governs STALKER. At one point, we were directed to a small group of STALKERs whom we would be able to trade with, but were shocked to find only their bodies, some bloody smears and a few sated boars. But in another player's version of the game, they were alive and friendly. Truly, each gameplay experience will vary.
