I have been watching most of the video coverage for this one and i have it preordered and i'm ready to roll next week. Something is the footage keeps coming back to me, it looks like the aliens just sit dormant in small 2-4 man packs until discovered by the player. As a big fan of the original i can say this was not the case back then. I cant help feel that one of the most dynamic elements (all of the unseen alien movement) seems to have been dropped.
Can anyone else confirm this either way? Having the aliens only start moving around the map after discovery is a bit of a letdown.
