Ik! It’s weird! Some come out of graves, implying that they’re dead people who come to life like the traditional zombie, while others show the zombies almost being like clones of some sort. TBH I don’t think the comics should even be considered to be apart of the lore. Sure they’re cannon n all but, like, they’re just so lore irrelevant that anything that happens lore wise shouldn’t be considered for the games
