Bursters- back, chest, neck, head

I get what you mean dk, but I see it like this; because the creatures rapidly grow after bursting out their victims' bodies, they probably grow from tiny to larger very rapidly and after a certain period within their unsuspecting hosts as well. 

I do however find the classic chestburster idea more realistic than the backburster, as bursting through the chest is probably the easier route than through a thick spine I guess.

I don't get why the guy in the AC trailer was having an epileptic seizure(!) rather than writhing in pain lol.

Let's not forget how quickly Shaw became several months pregnant within days or hours. Her acting here was actually very convincing (prior to receiving magical muscle tissue regenerating hyper steroids after the surgical removement)

In AR the dude with the glasses started having a feeling of discomfort and confusion well ahead of the chestburster emerging in a goreylicius fashion.

Resurrection seemed more realistic with displaying symptoms more.

The backburster puzzled me too. I would actually expect paralysis before the burster got out- not seizure like activity.

In alien 3 Ripley also suffered from various symptoms before she realized what was in her.But yeah i know what you mean.I've always thought they should feel some sort of heaviness in there chest or something like that.

Paralysis doesn't set in until the spinal cord is severed. convulsions are a pretty common symptom of shock. And I can say for certain that excruciating pain can cause shock and/or siezure like behavior. 

If you're concerned about a spine in the way, don't forget there's a sternum to negotiate through the front.

I for one do not see the benefit (to the universe) of having bursters via the neck, back, sack or crack.

If this is meant to convey the evolution to the eventual chestburster, well forget it because we've already got to it thanks to his right reverend the 'Deacon'.

I'm certain Backbursters only burst from the back out of convenience. Just like the Deacon tore through the Engineers entire torso with its' head, it did so because it can rather than it being some official thing; e.g. Chestbursters always come from the chest. As we have another Neomorph supposedly bursting from the throat.

It is more realistic imo for them to rip and tear from anywhere they can. (As long as they originate from the torso.)

Exiting through the point of least resistance makes more sense. The front with sturnum and rib cage seems most difficult. Lots of space in the back though.

As Neomorph says though, maybe they grow rapidly and don't have control over where they emerge from?  He/she would know ;) lol

I've always thought that to be the case with the xeno as how in the hell would you go about your daily business, even if a bit 'off colour' like Kane, if you had something that size in your chest?  I assumed the final thrashings to be result of the creature growing rapidly inside him before it makes its appearance . . .

In the case of eggs though, as opposed to spores, from what we've seen they always come out the chest.

We never really question it, but the chest has got to be the most risky exit point on the body. The ribs bend inward when they break. It's why they puncture lungs. It is realistic and likely that the burster would get stabbed or caught on the ribs as it tried to get out.

I know it's called a "backburster" but in this case the type of
"impregnation" isn't via a parasite, rather the spore. If the neomorph "bursts" from the back, the spine would seem to cause a problem, and the convulsions seem odd if the host is dead.

What if the spore doesn't develop into a "burster" but rather it changes the hosts DNA ala the black goo? So the bursting effect we see is really the actual spine of the host that's been transmuted into the neomorph. The concept art shows the neomorph looking oddly different than the traditional Xeno, so the spore could just alter the host DNA INTO a Xeno-like creature as opposed to just USING a host to incubate a Xeno-like creature.

Ironically, the ribs are the most fragile in the back. Much easier to break than at the sternum. Medical fact.

Good point.

The one shot we have of Mr. Rigby's back with some blood squirting out is all we have, but if you pause that image and look at closely, it looks like his entire spine is ready to burst out the back. It's shape is reminiscent of the Xeno design.

It would just make sense that the spore mutated Rigby into a Xeno, with the backbursting scene just be a way to shed the exterior skin, sorta like how a cicada sheds it's outer carapace. 

the title of the post sounds like a dance song....

"my neck, ..my back, ...my chest,... my head"

"Hey....Macarena"...

I think maybe its just a coincidence where the Parasitic Spore (i think we need to look at this as a Parasite that procreates like a Spore).

I had a problem with the Spore when it was first mentioned, it sounded not well worked out unless it infected a Pregnant Female or a Females Eggs...  unless the hundreds of spores released only ONE was absorbed (as then why not have multiple Bursters in one Host) unless these Spores somehow either by some intelligent or instinct design Merged in the Body and formed into a Organism.... or it was a Pot Luck Merger of Spores.

But since i saw the Trailer, it appears to be a Parasitic Organism...  or  a combination of Spores had formed together by the time it had gone airborne.

So i would say this Parasite...  enters the body via any means it can and by what ever means... it ends up at a certain point in the body and no soon as it encounters Genetic Material it starts to Form into a Organism... once this process begins the Parasite may move a bit until its formed so far.. then it stays in the area it has arrived at and then starts to grow.. using the Hosts Genetic Material to build itself..

Once it has reached sufficient size/growth/evolution it then proceeds to burst out of the Body by the nearest and quickest way it can.

Which if its grown in the back, then that could be the only way it can break out....

If it was in the chest area.... it could then crawl up and come out of the Chest or even Mouth/Throat areas.

For a Parasitic Organism.... by perfect design... then growing in the Chest Area works well... but then breaking out just below the Rip-cage and breaking out of the Belly Area would be the best method of escape.

@BigDave. You're absolutely right. I never understood why it tried to break through bone. Granted it's terrifying, but  not very practical.

Sorry, couldn't resist!
