Happy (late) Halloween! Thanks so much for all the support. What scared you the most about Black Ops 1 Zombies?

@EmmyEntropy2000

I remember as a kid with overprotective parents I had to play with gore turned off and voice volume off so they wouldn't hear the characters swear. As a side effect there were no zombie groans or Samantha announcer which somehow made it way scarier for me. Getting snuck up on and having no light hearted quotes made it feel 10x more isolating and unnerving.

@JRNY63

Another small detail about the Main Menu. When you're in the campaign section, it's pretty well known that if you just mash your aim and shoot buttons, mason will break free from the chair and can walk around the interrogation room.

When you choose zombies,
You can't.

@KnifeToMeetYou_

I remember how much BO1's Zombies menu was both really cool and really terrifying when I saw it for the first time playing at my cousin's house. Seeing the interrigator walk away and a zombie take his place, banging at the glass, what they had playing on the tv screens and the menu music. 
Best. First Impression. Ever.
Was the main reason why I wanted BO1 and why I still play zombies to this day.

@frisco9568

I personally believe that Blackops 1 had the best zombies feel and tone. Every map was eerie and ominous compared to what we have now. The limited knowledge about the plot and characters made things more mysterious and scary in my opinion.

@StriderOwO

Ever since I first played this game, I always thought that Mason himself turned into a zombie when you selected the Zombies mode, with the colors turning yellow like the Zombies' eyes and that horrific, fleshy noise that plays when you open the gamemode. Now, Mason's first person doesn't change, but maybe that's just because he's early in the infection process. Or maybe young me just had a really hyperactive imagination.

@mikedawolf95

All of the floors in “Five” tell a story, the offices were evacuated and everyone is gone and zombies just got to the floor, the war room looks like some got away but zombies were starting to break out of the basement. The basement lab is where everything started.

@juliovictormanuelschaeffer8370

Another scary thing from the main menu: it totally shows how alone and screwed you are. 

Not only there's a Zombie bashing the glass at the top trying to eat you, but then you realize that the pictures the TV's show are from no other place than the Pentagon itself, meaning that you're trapped in there like a tomb. Even if you escaped the zombie, there's still an entire building full of undead you'll have to escape from.

@stubrutv

My buddy and I always waited until round 20 to activate the hidden song. Mowing down hoards of zombies with 115 blasting in the background is a feeling that can not be replicated

@bossman4799

I especially like how the 4 DLC maps make you more and more isolated. Ascension is a Cosmodrome which is likely built in the middle of nowhere, CotD is at an abandoned lighthouse in Siberia, Shangri-La is literally a mythical place outsiders don’t/can’t go to, and Moon is well, the moon and you’re the only ones alive there.

@SuperSparrow45

BO1 Zombies really struck a perfect balance between the sheer horror and feeling of dread that WaW had and the off-the-walls mysticism and depth that would follow in BO2 and 3.

@DangerIncFilms

The funnest thing about the Moonman is that he’ll sometimes use the names of the people on your friend list. Just picture it. Your best friend has turned, and he’s coming for you. And he’ll get you, eventually.

@ScratRedemption

I found the spawn room of five to be like a safe room of sorts. No matter how many times you play the game, youll always start in this preserved, undestroyed room, fully lit with lights and knowing that few zombies will spawn. If you decide to come back after turning the power on, youll quickly find that your "safe place" is now completely gone, as the tv monitors show static or error messages, lights flickering between dim lights and darkness, all while the quickly moving and bullet absorbing dead are surrounding you on all sides. Your safe place has become a death trap, and will be your grave should you decide to stay for longer than a few moments. Say goodbye to the room you once called safe, for everywhere you go now, you're running from your inevitable demise, and you'll die tired.

@cillbipher2613

Another creepy thing about Kino is that along with the ambience, Damned can be faintly heard in the background.

@dylanchilders

Describing Five as a haunted house is so perfect, it feels like a high end Disney or Universal Studios haunted house, where the first floor is like the queue area where you wait in line and just take in the environment, then the next floor down is like the room where you would board the actual ride or something, and from there you descend into the absolute horror of the Five labs, brimming with human experimentation victims and horrific sights, only to turn on power and escape through the portals. The map is such a unique and intense experience

@ashamefulgamer1578

It's poetic how Romero is the only one who constantly walks around and never runs unless provoked.

@gamingmoth4542

8:52 I also like how they took pictures of real life Germans surrendering and then edited it to make them into zombies because a human soldier and a zombie are quite different. Humans have the capability of self preservation, but zombies do not. Zombies don’t care how well armed their opponent is. Zombies don’t care about how injured they are themselves. They will stop at absolutely nothing to try and kill you and their persistence makes them a massive threat.

@expio4257

The "Void Barrier" is actually just straight up a black room.  There is no lighting bug, the textures inside the room are just pitch black.  Less scary and more just lazy to me honestly.  The barrier in the dressing room with the pounding is easily the scariest part of Kino for me.

@PR1ME98

Five and moon are without a doubt my most favorite cod zombie maps of all time. Both really give you that “no hope” feeling

@connortollit6120

I miss how the older maps had new and different animations, pretty much every map from the start of waw to the end on bo1 had unique zombie animations and it was a really cool touch.
