A couple decide to move in together. That much sounds simple enough - except that it isn't when the whole apartment complex is crawling with zombies, werewolves, and succubi. He's a half-skeleton with a functioning lower body, while she's a full-on zombie, with mostly intact body parts. Still, you gotta watch out for the occasional nip- no, liver slip!
