What Happened to the Engineers on LV_223?

Some of you have gotten close but drifted off into fantasy, here's what happened... Pre-2000 years ago an Engineer craft was forced to land on LV-426 when the pilot fell foul to one of his cargo. As a result the Engineers on LV-223 redesigned the Xenomorph, changing it from a biological weapon to a viral weapon, by reprogramming the black liquid used by Sacrficial Engineers to "Seed" life in their image upon fledgling worlds, to create a new strain of Xenomorph that could spread quicker. This is what they intended to use on Earth 2000 years ago to mass produce the Xenomorph using us as hosts, this is why they seed life - to create viable hosts using their own DNA to create en masse, the Xenomorph. The intention was to create a safe means by which to transport the Xenomorph using urns, but the substance was so volatile that one of the Engineers became infected whilst in the ampule room. The other Engineers sealed the door and its contents away, quarantining the Engineer, but only half (titter) of him was inside the room, the other half allowed the Xenomorph to spread throughout the base/temple killing all but one of the Engineers.

Maybe the engineers where runnig to that room to protect something,the mural with the alien on it could also be a door.Everyone seems to think the engineers developed this black goo,but what if they where extracting it from whatever was behind this mural.Also,could someone explain why the alien in the mural looks like it is being cruxified just like Jesus was?

[i]Also,could someone explain why the alien in the mural looks like it is being cruxified just like Jesus was?[/i] That parallel was unnecessary, in my opinion. The movie made one too many references to Christianity for my taste (blame Fox?) but then again, you could also think of Ripley in Alien 3. She dies in that position too. It also seems like an unnatural posture for a Xenomorph so we're not talking about a whacky version of Da Vinci's Vitruvian. It's a clear nod to divine worship, but why? The moment we see that "xeno crucific" and the green crystal, Holloway says: "It's just another tomb." I know, I'm not helping.

This is just about the xenomorph targeting only humans is wrong alien3 has the answer to that. Also to the ties from movie to movie in aliens doesn't bishop mention about a older model going haywire(maybe he was mentioning rippleys previouse encounter with bishop'1waylen is a company thru out all the alien movies and the xenomorph was the basis of the movie(s).. And just another thought what if the engineers ment to create the xenomorph as the so called perfect life form.. Pure rapid adaptation.. The black goo for whatever reason gets bubbling maybe because of David being a button pusher, the goo drips on to the floor in which there seems to be maggots or larva worm things. The black goo being xeno in liquid form (possibly because of the martyr in the beginning doing the contaminate the water supply, turning it into TBG) anyways the T1000 version of xeno infects the maggots creating what I call the lil beauty (per the ones who get the business from it call it that) or worm things. An then the natural instinct of the xeno (programming or otherwise knowledge of what to do like capture as many hosts as possible to progress the species. And if someone can tell me how a queen is determined is it just a host that has a reproductive organ as in female like or if it used a "A" sexual reproductive species like with frogs I believe can do that does that mean one xeno could rapidly self produce?

Near the end of the movie, David says to Shaw that its not the only ship. That means there are many other installations, each with its own Jagger nut. Its one of such Jagger nuts which Shaw boards and make her way to the SJ's home world. Had all of these installations got infected and all the SJ's dead?? After all in the movie we just saw one of the installations which the crews of PROMETHEUS explores. What happened to the others....??

I believe they were chasing the space jockey because the title prometheus was used as a name by a titan who was punished by the gods for giving man fire. Which the Space Jockeys (the titan) must have created humans but also giving them "fire" (invitations). Which the other Space Jockeys (gods) did not approved and might have got angry with them and decided to kill them as a punishment. Which may have lead into a war with eachother and one of them try to escape by sealing the room but some got in except the unlucky decapitated one. Whatever happened one survived to try and wipe out humanity. This is what I think? But its a mystery that can never be solved.

maybe the pile of engineers were test subjects that went wrong so they piled them up to dispose of but something went wrong before they could be moved, just a thought.

@BRODO.... alien 3 man...the xeno was born from a DOG...Obviously the face hugger attached to the k9... @snorkellbottom...its not just you man...and i think your well on too something..but still these little things arise for me to question...but ....why would the rest of the engineers run INTO the ampule room you say the last engineer was infected by and in..as to risk infection themselves...apologies if i misread your post but i read it twice. 2ndly everyone seems to overlook that they where wearing their BIO (spacesuits) forms designed for intergalactic space travel...is it really plausible an infection air born or otherwise could penetrate these suits? designed to protect them...it didn't penetrate shaws or holloways or anyones run of the mill 'Human' suit. and as stated in the film later on...david (despite the goo being all over the floor) is adamant to shaw that its safe to take of their helmets when they're walking with weyland as shaw is concerned that an infection/contamination is airborne...because holloway got infected...but as we know david did that...so despite al this stuff and goo and cobra worms running about the place it was still 'SAFE' to walk around with NO helmet on...all great theories but what about the facts of the movie first and build from there. i'd put a thread about this up just yesterday about this stuff...and quickly here's my 2 cents about the point and questioned asked. i'll try and keep it quick and to the point..... TO ME...the engineers where running from an outbreak yes...but not a panspermic...or contaminative type. but more of a nested infestation type...of creatures...like the face huggers...or some variant of these creatures....wether it was a controlled or accidental outbreak we just don't know. The Engineers in their biosuits looked ready to leave the planet...***but i have to say the engineer that was awoken later in the film was wearing a different garb in the cryo pod (of which there where four) until he was about to fire the ship up and leave where his bio suit encased him in the pilots chair...so where these other engineers pilots or 'Captains' of the other vessels and subject to a conspiracy possibly started by the sacrificial engineer who took the black goo to intentionally escape and start life on earth...which also sets in motion the idea of warring factions.... which is why none of the other ships left LV223 planet to (supposedly) go to earth. as david says "there's lots of them" and other engineers in the other pyramids could be in cryo..or dead at the hands of the rebel sacrificial even double agent style engineer*** back to the question. Engineers being chased by these Facehugger types or variants .....run into the first open chamber they see (wouldn't you)...hit the close button and the last engineer doesn't quite make it (for what ever reason) and is decapitated. as for the last engineer (head) being infected...i actually don't think so....if you put an apple in a bag of onions and leave it a few days....the apple starts to smell like and to a point taste like an onion....so i think the decaying head picked up/absorbed particles of the atmosphere and what was in the atmosphere around it, like most if not all decaying or fossilised artefacts we found in the world today...and as we know if it was an infection...it wouldn't have stabilised it would still have spread..hence things like the plague...the body maybe dead but the infection is alive and why it spreads in the atmosphere to others. but as i've said earlier...despite being all over the floor..this didn't contaminate the "air". no i believe the electrical stimulus applied to the head just like the atmosphere triggered the particles in the engineers head that where absorbed...and accelerated so quickly as to combust...and really if you think about it his body out side the door didn't seem to have any of these symptoms of contamination in the change of atmosphere when the team arrived. So. the bunch of dead engineers piled up outside the other chamber door with the holes in the chest....and the head (exciting thought) i believe where either a further bunch of engineers/pilots/captains (captains cringe i know) who climbed over each other panicking trying to get INTO this other chamber knowing the danger that lurked. or indeed where the same ones who entered 'OUR' chamber and where still caught out by the face huggers....HR GIGERS mural shows that the engineers knew all about the xeno face hugger life cycle ...therefore knew how dangerous an outbreak was...where these creatures went after they burst out? ...who knows there's no sign of them dead or alive...but again considering we only seen about 15% (guess) of the pyramid they could be anywhere. its also plausible that the last engineer (at least in out story) either controlled this outbreak, or closed the door on the dead pile of engineers...or both...to keep himself safe as to carry out the mission to earth and try to overcome the betrayal (he would see it as) by the creator sacrificial engineer....it is called 'Prometheus' .as well as just maybe being lucky and made an authentic escape.....but then why didn't he leave and continue on then?....too much to consider...thats my logic to it. ... at least to this individual point.

Just another curious observation but: If the Engineers have been dead for 2000 years, why would the decapitated head be in flesh form? Wouldn't it have decomposed to the bare skeleton after say a few centuries at most??? So when they take the engineers head back to the ship and reveal a slightly fresh, fleshy head inside the helmet, wouldn't that have indicated something's amiss here? also: - what was the life form that was pinging in and out from the pup(this happened before the black goo was found)? - what was the green goo that David found on the wall/panel? This would indicate that a creature was alive and roaming around since 2000 years would have decomposed this slime as well - what was the deal with the open sequence of the engineer killing himself over the waterfall and the "mothership" taking off? this seems to be the key to the whole movie, no?

Has anyone stopped to consider the following: All of the 'star maps' left to various ancient civilizations on earth all lead to NOT the engineer homeworld, but this military or scientific installation? It seems that the engineers were not leading us to a friendly welcome to begin with... Did the one engineer in the beginning of the film not agree with that?

Matt, I thought that was weird also. I think this invitation was actually a warning. Just as in Alien the signal turned out to be a warning. Perhaps some friendly entitie wanted to give the humans a heads up.

@facehuggerlover @matt hi guys just a thought to your question Matt...this wasn't a big point for me mate as i had taken it...that it was the Star System in is total...that the cave drawing and constellations where pointing too the drawings weren't pointing specifically to lv223....THEY (Shaw and Holloway) decided upon LV223 because of its nature and adjourning sun where they'd hoped and said that one of these planets in the system was approachable in its condition of supporting life which was lv223 it doesn't mean thats where the engineers came from specifically but is part of their solar system ....it kinda makes sense when you think that its well documented that lv426 is a neighbour of lv223...and even bigger suggestion is the the engineers planet IS in that star system....like the sun moon pluto uranus etc are in our star system but light light light years apart....keeping a safe distance...yet easily approachable cause of their technological advancement to get there....it doesn't seem the engineers need oxygen to survive...as the engineer at the end chased Shaw with out a biosuit on out in the open...which would make their planet unsuitable for us...therefore we wouldn't choose that star...hope that helped your idea...not saying I'm right...but thats what i took from they start especially cause shaw and holloway say in the movie thats why they chose lv223.

For those out there that HAVEN'T really seen "Prometheus" (but are just ranting about how HORRIBLE it was) and, for those that DID see it...and were NOT impressed... Allow me to present my own " thinking persons interpretation" of what may have happened, and of what many may have missed in the "storyline" of the movie (and YES, obviously, I HAVE seen the movie). *WARNING: MAJOR SPOILERS INVOLVED! * ;-) First off : the movie WAS entitled "PROMETHEUS" for a REASON! http://en.wikipedia.org/wiki/Prometheus The opening scene depicts an "alien" being, standing naked and ready to sacrifice himself, by opening a (STOLEN) small canister of "something" that he ingests...and sacrifices himself to create (ultimately) mankind... while the (COMPLETELY different from any other in the movie) alien craft he arrived in, hovers overhead...and then departs. From here on out, for "clarification purposes": I will refer to THIS alien AS "PROMETHEUS". When Weyland's ship Prometheus arrives on the planet that "PROMETHEUS" escaped from, with the power to seed planetary life : the crew finds all of the other aliens dead except only one, as a result of "PROMETHEUS" sabotage, while making his escape with the power of creation. THAT was why, when the only survivor "alien" was awakened...he was so ANGRY... and wanted to kill all of them...and THEN get to Earth to wipe out the rest of humanity. And that is the answer to Elizabeth Shaw's (Noomi Rapace) question: (paraphrased here) "Why did you create us...and now want to destroy us?" Just my thoughts on the film. Going to see it again...just to see what else I might have missed. ;-)

Only thing I can see is that they were running from something and seeking shelter. Maybe that thing in the mural has something to do with it and the Prometheus crews were lucky not to have found it. Weird thing is that it looks like nobody made it to the shelter places as all the bodies lay outside. At one point it seemed to me that that planet may have been some sort of penal colony and weapons testing lab...

@donalddinks...hi man...nice to see a good post...but theres quite a few of us myself included....who have pretty much written the same thing give or take...am i missing something or is that much not kind of obvious?...i'd always felt that was the story....the gripe i've had with this film is that this subject matter...plus the intense story build up where abandoned...giving rise to all these speculations....and questions like the one at the head of this thread....id even written without going into detail on this thread...about the possible conspiracy against the engineers...on lv223...and that the last engineer was the only 'lucky survivor' of this conspiracy nae outbreak....and is why he deduces that these humans he encounters are the fruit of the betrayal he and his 'pals' hah! suffered and reacts the way he did....having said that the film is so city and distracted for me....that we find ourselves caught up in these threads looking for plausible reasons...to the other parts of the film...that dropped (for me) the narrative.

Donaldinks, great idea. I do see a problem though. Wouldn't that mean the engineer would have been in cryo sleep for a couple billion years while humans were developing on earth. It might not be a problem at all, just thinking its hard to fit into the timeline.

The sequel will clearly characterize the white "engineer" aliens as evil and their black overlords as good. This has been planned in the treatments.

i had the same idea as scotty123 . the Engineers had an enemy. the were creating/ bioengineering the zenomorphs to use as a weapon against that enemy. Humans were made as a way to farm hosts for the zenomorphs. but what happened is the speed of the life cycle caught them off gaurd. some of them got infected by the little wormies and destruction ensued. there is no proof as someone else suggested that it happend to ALL the ships/bases on the planet. most of the others may have gotten away. all we know is that at least a few ships remained behind. at least one was taken by elizabeth. the other thought is that they were trying to create one thing- life like themselves to seed the galaxies but they- like the humans that trampled them on the way into the room- were just not paying attention to the little wormies in the room. they maybe spilled some of their black seed goo and didnt think anything of it until the little wormies turned into things that shoved themselves down your throat. the reaction of the one surviving engineer is because he realizes he's still on the base , figures that anything human that he sees around himself is infected and wants to get the heck out of their as quick as possible to find out how long he's been asleep and what happened since hes been in suspension.

@facehuggerlover.... thats a real good point man...but i believe this is where the warring factions come into play....its an intergalactic war of factions...engineer lovers and enginer haters....and fits in with many of the iconic multi religious stories and depictions of the heaven and hell wars....(or whatever they maybe to what ever religion) that the sacrificial engineer...chose to begin mankind...for whatever his omnipotent reason...he believes its right..(prometheus steels/takes the fire)...he's not going to show the engineer haters where he hid/or used the fire..for them just to come along and extinguish life...this war is eons in length and ongoing again as described in many religious texts....and these engineer lovers visit earth in our ancient to recent past to teach us and look out for us....when the haters finally find out where we are they're on their way....(as i don't personally believe they where going to infect us as hosts for face huggers and xenos...to what end) but again a sacrificial loving engineer sabotages them and probably himself...to save mankind....and we are made from their ultimately (despite the shit in the world today) loving and sacrificial genes....hence the notion of Shaw but more heroically JANEK (although the scene was badly handled imo) to instinctively want to save humanity from the hater..as it where....what ya think?

I'm intrigued by the fact that all the Engineers were all wearing suits when they died. The masks indicated that they were probably using respirators of some kind, despite the area being fully breathable. Furthermore the black goo was not know to cause problems as an aerosol. This leads me to believe that there could have been a war on the surface, and that they ran underground for protection. Plus, they seemed prepared to be in harsh conditions. At the same time, the problem can't be some breakout due to problems containing the black goo. So from this, I can theorize that the Engineers WERE attacked by some 3rd party not shown in the movie, and that they knew about impending dangers.

@xeron..yeah man i absolutely think the war is the way to go...i agree as I've written in an earlier post on this thread...that the airborne threat is unlikely to have killed the engineers for the same reasons as you've written...but they must have been infected with something...an outbreak of face hugger type things...just because that pile if engineers have burst holes in their chests and head...i think the 3rd party your referring too are actually the side of engineers that want to protect and created 'us'...so 'they' or even 'one' of them sent in motion a plan to destroy the engineers with their own (possibly shared) bio weapon...i'd go even a little step further as the murals depict a pet type or other type alien at the feet of an engineer...but also in the cave painting too this could be the loving sacrificial engineers version of the xeno which has a different but no less scary purpose....alls fair in love and war right.

Going along with my "superweapon" theory, here's what I think happened to this ship. The Engineers picked up various mammal "hosts" from Earth, including at least one human. They start to incubate the hosts with the goo, but the human unexpectedly turns out to be intelligent, and escapes. So the xeno emerges somewhere in the ship and runs amok, killing much of the crew. (Note: another possibility is that all of these were killed in one spot by whatever the Engineers were using to kill xenos -- fire, gas, etc...). The remaining Engineers record a warning message saying "holy crap, a xeno got loose!" and "humans are dangerous, we have to destroy Earth!" Then, because only a few stayed alive, they go into stasis and wait for reinforcements.

I think that the engineers were killed by another alien race. That race is called, what we know today as the Space Jockey. I have always thought that the engineers we see in Prometheus are different from the famous Space Jockey we see in Alien. They are two races of beings. The Space Jockey race is taller and much wider at the shoulders. But the biggest difference is that the heads of the Space Jockey is really elephantine. What we see in Alien is not the Space Jockey with a helmut on. We are truly seeing his actually head. Can't you see that it's nose (trunk) runs from the nose and is attached at the chest. Thats no helmut.

Just some more thoughts to add to my earlier post: Where are Elizabeth Shaw and David heading to now? To find these ORIGINAL BEINGS home world. The one they are now leaving was merely a Military base… producing weapons of mass destruction. One that (obviously) a “renegade conscientious objector” rebelled against… …named “PROMETHEUS”. Was that military base and their agenda against certain others of their race an abomination? Did others, then “conspire” with “POMETHEUS” and enable what he accomplished??? Ridley Scott will explain...later. Cheers! ;-)

@ribirosa...possible scenario my friend...but the trunk like features of the bio suit in the prometheus engineer also run into the chest...the decapitated head...has it's 'nose' broken in half ...so is that why you think it's not attached?..i agree in 'ALIEN' the SJ looks a lot bigger that the prometheus engineers so theres a plausibility....but we just don't know how relevant that is just now...especially because the bio suits are built into the pilots chair of the ship and enclose the pilot in it as they're getting ready for take off and look exactly like the SJ's we all know about....seems a long way to go to mimck something thats trying to kill you...but like the 'out of the box idea' @Baronxenomorph...can i ask you what your baseing that theory on?

[i]Why were the Engineers seeking refuge in the Ampule in the first place? Where did they go? Were they eventually found in that room and dragged to where Fifield and Milburn discover their dead remains?[/i] - Well, I think that Engeneers got out of the room (the way they got out is irrelevant), but we, neither the team of Prometheus, saw the hologram of them getting out. They probably got out eventually, but it doesn't matter how. And yes: [b]From what were they running from?[/b] Maybe the Engeneer was actually going beserk, if he wasn't then something (that they were running from)didn't bother with his body, the Engeneer's body isn't moved at all.

@donalddinks.... it was Shaw and holloway that chose to go to LV223 because they said that its near sun made that particular 'rock's condition more hospitable and visitable...the star constellation depicted in the film is more likely the star system the engineers come from.(or have an outpost type planet and is the closest visiting point in relation to earth)..but at no point does the cave drawing(s) specifically point to LV223....i think its likely that in the engineers star system they indeed inhabit one of those planets...which wouldn't be supportive to our life system...considering LV426 is a neighbour of LV223 its not out of the way to think that the engineers come from that system and keep their military base far enough away to be safe yet close enough to get to easily 'commuting' with their technological advancement like earth to pluto or uranus....same system but light light light years apart...the world is our oyster....the universe is theirs...so in summation...they 'Shaw etc) made a mistake in visiting the wrong planet in the system for answers...but the right one in terms of hospitable sustainable condition....

Galzu, I completely agree with you. they were running from the aliens which must have been an outbreak. they must have created the humans then for some reason which we are unsure of decided that humans were bad and needed to be killed so they created the "black goo" as bioweapon of mass destruction which they produced on this other planet in case an outbreak happened, which it did. and they were unable to carry out their plan. and when the one woke up from the cryo chamber he knew that the humans were to be killed and tried to kill them to carry out his mission and the ship (which we know their were multiple of) was carrying the canisters (the bioweapons)which we saw thousands of in the ships hold to wipe out the entire human population on earth.

I think the bodies are just in front of some doors ( the doors look like the ones where is the human face ) so mby the think killed them is behind the door and engineers wanted to stop it at all cost so they managed to close the doors but at the cost of their dead. There u can see it its from the Art book i think [img]http://i.imgur.com/8GzSt.jpg[/img]

I don't think the surviving engineer is at fault. I think he's their Ripley, surviving in stasis until possible rescue. All it would have taken is one opened or broken canister to destroy all of the engineers who weren't protected from that environment. I think the last engineer just got lucky when he got in the pod. I am reconciling myself by thinking the goal of the engineers was to populate all the planets with the goo, sacrificing one engineer and one canister per landing. They may have started with Earth, flying their one large disc ship to the virgin planet and dropping off one engineer, then leaving to observe. Then years later they check in. Then they discover we are hell bent on destroying ourselves and worshipping other creators, so they decide to annihilate us. I think they wanted to annihilate every impregnated planet's population before we stumbled upon an intergalactic link up. That would explain the wrath of the engineer who woke up 2000 years after his alarm clock went off, and was like "what are these things yelling at me in that strange language - oh what, was that Sumerian?! Humans!?!? Must kill all before they spread!!" Either that or the engineer race recognized the human race that evolves has reached the end of their evolutionary biodiversity, approaching that of the engineers, and they decided to add a little fuel to the (promethean) fire, so to speak. What I can't work out with that theory is why they would want to populate all the planets. I understand a central theme is creation, and the ambition to create (become, in essence, a 'god'), but on such a massive scale?

Thanks for agreeing with me @Nickell.

Just wanted to contribute, I'm watching Prometheus now and just noticed a flaw in one of infidels theories, when the engineer holographs are running the last one that you said may have been infected looks back as he is running so that would seem illogical if they were running from him

Gratqaz: If so, a valid point -- I must have missed that.

They had to have been running from the aliens. such as the ones from Alien Vs. Predator. This entire movie ties into AvP and in the very last scene we see one of the aliens are hatched from the body. there must have been an outbreak of the aliens in the facility. we already see the "black goo" can cause the aliens to be hatched in some way. the "squid" must have implanted an egg unto him.

we know the engineers were on a mission to wipe life from earth " which was obviously one of there creations and which spawned the major question at the end why would they want to rid earth of life after they created it" so the engineers came to the installation to collect the weapons to destroy life on earth when things went wrong and another point ..just because it was a military base doesnt mean they were not experimenting with there biological weapons and improv ing them so maybe it was a military bioweapons research and storage base.....so i think when the base was contaminated all the engineers were killed and the survivors went into hyper sleep intil the contamination was gone....and maybe the base was under a type of quarinteen we dont know what time means to the engineers 2000 years could be nothing..and i would love to know what is in those other rooms

I believe they were running from there own creation like capt. Said it was proable a military site with them being so hostile so odds are one of those creatures got out or maybe multiple of them where chasing the running engineers so the engineers wanted to be safe and go to the nearest place that could offer shelter also everyone is talking about the one surviving engineer killing everyone if you look close at the pile of body's there by a door so they had there back againest the wall and were trying to get in(I'm sure someone locked them out)and thats my theory

Before David starts the hologram playback he finds a different type of goo on the wall than the black goo we see the restvofvtge movie. Then as stated already we see the last one look back and fall and then the door cut his head off. It does seem that an outbreak took place.. Through out the film David's character throws caution to the wind not considering the safety of those around him.

Oh my god, this discussion also leads to shaw's thinking, why the engineers created us and want to destroy us? Well, according to my assumption is that there are good and bad engineers in LV 223, as the temple with the humanoid head, are the "facility" that some sort of experiment was going on and those engineers were try to stop it or something. However, this reflects me to the thinking that when charlie discovered an "alien-figure" on the wall behind the humanoid head, and also a door that could lead to another passage, is this really means something, something that aliens had arrived on LV223 long time ago? even Now im confused......

WARNING- possible spoilers Ok, so this is a little far out there but my prediction is that the engineer found on the derilict ship on LV-446 was not an engineer but possibly shaw. She was flying one of the ships with the help of David. As we all know senthetics have a history of betraying the protagonist in the films. My theory is David had alterear motives to helping Shaw. I believe he at some point possibly contamiats her causing her to become impregnated this time with a pure form( the xenomorph intended by the engineers). It bursts out of her chest, becomes a queen and lays the eggs in the ship. David then sends out the distress becon to be later picked up by the company. Now I know whats going to be asked where was David then when they found the ship, well the ship was rather large and they didn't explore the whole ship. Or David could of been destroyed by the Alien, we all saw how the queen reacted to Bishop in Aliens so I doubt he lived in harmony with them, or his power finally ran out and he went dead and they simply didn't find him. So what do you think, I could easily be wrong and I've might of forgot a few points but I think its a pretty good prediction.
