Well, why not? There are many films and books where vampires mutate into various creatures due to a lack of blood or if they attack their own kind. Let them become werewolves; people will be amazed:D :D :D
Hmm, for project NCF, I personally like this idea, but we need to think through all its parameters and appearance. As I understand it, when it attacks, the vampire should change its visual appearance - however, it is difficult to implement such an idea beautifully...

I just opened the archive, opened it, put the folder in the date, and it seems to give 400 blood right away, but the damage ignores the blood; the blood remains, and life is taken away.
You don't need to open the archive; you just need to rename its extension from .zip to .pak.
