I know it was just a trailer but I saw a few things that made me wonder about the game. DId anyone else notice that after the zombies busted into the room the fat zombie stopped to pull the axe out of him before going back on the attack? When the zombies swarmed the wife it lookd like they were trying to keep her from using the knife and the last thing I will mention is that when the father cut off the "bikini zombie's" hand off it retreated instead continue it's attack. i have seen a lot of zombie movies and never seen them behave like that. Like i said, I know it's just a trailer but I just found those things odd....just figured I should point out what I noticed.

I think you're looking too much into it.

If the zombie with the ax in him was intelligent, he would have used the ax, not drop it.

that would be pretty god damn awsome.
