Seems cool enough. I am a little troubled, however, that escort quests may be the focus of this game... Also somewhat underwhelmed with the attempt at horror. The flashing pictures of corpses? Ruined my opinion of the whole thing. That is to say, I think the trailer kind of screwed that up. Bodies pinned to the wall, hung corpses etc etc is definately disturbing. When you walk into a building with minimal lights, a radio playing somewhere in the distance, and after searching claustrophobic rooms you find the previous occupant butchered and strung up, that causes a sense of dread.
It's not a zombocalpyse, as many of those before me have rejoiced at, as I too am glad for. But if that's the case, the fear needed to come from not what is hiding in the shadows (Cannibal rapist survivor gangs, I am hoping), instead from that which isn't there. Police. Civilians, friends, company. Fiends stalk the city, and you, friend, are all alone.
If you cut the combat, made the exploration of this abandoned, ruined city the entirity of the video, THAT would have been powerful. But there's is at least two survivors shown, including a little girl. It just loses the impact. I mean, that kid survived, how hard could it be for you?
