While this looks absolutely fantastic (cloth physics, lighting and texture work is all best in class) and I know it's a trailer so they have to show something exiting. I am starting to get a bit worried they are going to far towards the the CoD roller-coaster school of design, wall to wall highly scripted action is not what I want from metro, I want the atmospheric tension of creeping around in the dark making mad dashes out on the surface etc with precious little ammunition, and groaning whenever I lose a throwing knife. And very little of that is shown in these videos, I hope they do some Dues Ex: HR or Far Cry 3 style multiple run though demo's that show multiple paths and less scripted combat sessions.
