The Anatomy of a Zombie...

So, let’s get the point straight out of the way. We’ve all seen that headcrabs (mainly) attack from in front. In fact, when Lamarr jumped on Barney, I’m sure he got on from the front. So, may I ask, how do they end up facing the complete opposite direction on a zombie? I guess they can attack from the back, or turn, but it honestly just seems like they attack from the front.

Thoughts/Ideas/Topic closers go below.
Unless you flipped your computer/monitor. Then they can go to the sides or above.

maybe they have to turn around sometime after they latch onto the victim’s head, maybe to help with the zombification process, or maybe because it’s more comfortable.

Or so they can see where they’re going.

tbh, I expected a thread with diagrams and speculation about how the zombies work. I am disappoint.

with what, the eyes they DONT have?

Maybe it doesn’t really matter how the headcrab gets on the head, but how come the zombies have gaping holes in their stomach and long claws
Seriously

Because he’s infected with [COLOR=‘Black’]head[/SIZE] crabs.

Claws are from the mutation process, the headcrab makes the host better suited for self defense. The gaping hole, or at least in the booklet that came with hl2, is created by the host ripping it’s own chest to provide an open exit for the headcrab’s eggs it lays inside of the host, and so that it can eat, by putting food in it’s tummy.
Which is a bit odd cuz I remember the gonarch being it’s form of reproduction.

The common theory is either that the Combine modified them when they were weaponized, or the headcrabs on earth have mutated or evolved so as to not need the Gonarch stage.

Alternatively, who’s to say there still isn’t a Gonarch stage? Even terrestrial organisms can have insanely complicated and seemingly mutually exclusive, reproductive stages.

Thank you, MR. SPESS MARIN.

i always thought that the headcrabs leap at ya head and have a chew, then attach properly :\

Maybe these are a different type of headcrab, an attack headcrab or somehting lol

well, there was this thing from the HL2 beta:

The headcrabs themselves have no eyes and they can find their victims. Once attached, they cover the eyes of their victims. In the case of the zombines, they completely destroy the victim’s head. It seems that the headcrabs simply do not need the victim’s brain or senses at all, and instead use their own senses while controlling their host via a connection to their spinal cord. This is why the headcrab zombies are still able to cry out in pain. More mysterious is how the zombines create a synthesized voice without a mouth. I’d venture that their voices are somehow projected with speakers from their bodies (for what purpose I don’t know) and are tied in to their nervous system somehow, allowing the connected headcrab to make guttaral synth sounds. The only evidence I can think of for this is the hole in the neck of the stripped Combine soldier -

Just an idea.

I’m confused, how does the Combine soldier’s neck-hole connect to the headcrab’s vocal mechanism? I’m pretty sure you know that headcrabs are living things.

You’re assuming that, if the headcrab really ate/disposed the head. What if your shotgun blast or gunshot riped the head off, and headcrabs actually use the brain?

Brain is a terrible thing to waste, and it’s more useful to reprogram it. Also, it would explain the chatter that comes out of zombines

^ This. The brain and most of the head are preserved during zombification. Headcrab attaches to host’s nervous system trough the brain. Zombie and zombine sounds are produced using the human’s speech organs. Also, the host is still somewhat aware of itself, which suggests that their brain is indeed still present and not completely taken over by the headcrab.

By looking into this thread, you can get more info about how “headcrabs” work and how do they do their jobs.

Also, what bothers me is how the fast headcrab were made, and how does it manage to destroy half of the human body, only to make it achieve greater speeds and agility. Same goes for the poisonous headcrab

I still don’t believe headcrabs always need a head. First of all, no matter how you kill a zombine, it will always result in a headless body. Just to test it, I started up Episode 2 and shot one in the legs until it died. It left behind a headless corpse and a living headcrab. So, since there is no model for a zombine with a head, it must always be destroyed in the coupling. (The wiki also states “The official Prima strategy guide for Episode One indicates that the lack of a head is meant to be an intentional mystery.”)

Second, I know this might be viewed as invalid since it addresses the way the game works, but when you kill normal headcrab zombies, you are never able to blow their heads off. It’s a capability of the Source engine, as seen in L4D, but it doesn’t happen in Half Life 2. Therefore it’s impossible for you to blow off a zombine’s head.

Third, the headcrab does not really need the host’s brain. It only needs its host’s body in order to protect it, and to lay eggs in. As long as the headcrab can control its body, what is the point in getting attached any further? It has its own senses to get around. Attaching to its host’s senses would only cause it a great deal of unnecessary pain, with all the damage it causes to its hosts. Also, headcrabs are not smart enough to make use of human intelligence, and even if they were, the damage they inflict on their host bodies will kill them before long.

Many interessting theories here. I’ll give it a thought and post my own theory later today.

Or they just simply don’t want to see their faces

If you look at any parasitic organism on Earth, you’ll notice that none of them kills their host, because they need him. (same goes for the brain) They need the brain, they need the body, they just reprogram the brain. It’s like you make an orange juice, but without orange.

Or we could talk about disposal of brain, but leaving the nervous system intact?

But then we have another problem, if headcrabs do dispose the brain, explain talking zombies? You need a brain for that high level function
