The Last Stand/YMMV


 * Demonic Spiders: In the first two games, running, fat and weapon wielding zombies. They've got high health, they run and they can kill your survivors through the barricade with their weapons.
 * Also, running and weapon wielding SWAT/soldier zombies. They have bulletproof vests and helmets, run, and can still kill survivors through the barricades.
 * Goddamned Bats: Zombie dogs. Unless your barricade is down in the first two games, then they become Demonic Spiders.
 * Good Bad Bugs: It's possible to lose survivors on search parties at random. This can still happen when you have no other survivors with you. Basically, the one survivor you have (yourself) can die on a search party, possibly multiple times, and still go on slaughtering zombies.
 * High Octane Nightmare Fuel: The death scene involves your character being tackled to the ground and eaten alive by zombies as he visibly screams and tries to fight them off. This isn't a cutscene either-it's a death animation. Only lessened by the Have a Nice Death message.
 * Some of the notes in Union City can count too. For example, there is a very poorly spelled note from a little girl whose nanny told her to leave a goodbye note to her mother, ugh.
 * Nightmare Retardant: Many of the notes were community submitted and contain high levels of Narm.
 * Hell Is That Noise: The sound of your chainsaw stalling. When you're using a chainsaw in this game, you really don't want it to stall.
 * Also, the groaning-moaning-scream-thing that some of the zombies make will haunt your nightmares if you play for too long. Although that's more the product of lots of deaths.
 * The Scare Chord that plays when a horde is about to attack. It also comes with the sound of the ceiling breaking when indoors.
 * Straw Man Has a Point:
