Was watching the story trailer

I noticed two moments from the trailer that are not in the game
@ 1:10 - There are no enemies in that room in the finished game
@ 1:14 - Pretty sure there was no infected moment like that or that the infected even feed on corpses
@ 1:15 - No enemies in that area
not sure about that particular moment, but you're so wrong on the infected not feeding on corpses. there's at least 3 infected feeding on humans during the outbreak scene. during the first encounter with infected (during actual gameplay), 2 of the 3 runners are chewing at someone... pretty sure there's more, like the scene from the vid, but these i remember very clearly.
