I don't know about the status of VR. I think if we did it, it would be basic.
I don't remember seeing Play as Zombie in the Kickstarter and I've not heard it seriously mentioned.
I would guess PVP will be more refined at some point, but I don't think anyone wants to tweak it until features and values are near completion.
We would like a return of horde mode. I have heard about the old version, but not played it.
I put the extra a in there as "fatal" tends to be already used. I started doing that for my WoW characters.
