That was good, pretty difficult sometimes, oh also best to keep the doctor locked up that way you don't leave out anything helps to unravel the mystery much better, from what it looks like, it was a little of both it was a virus, but it also looks like the shadow creatures are not zombies at all, but actually something much darker and much more sinister from the other side, pretty dark, that cliff hanger though ordmand had us all fooled too, I hope you do make a sequel I wanna see what happens next.
