Slime on wall / control panel, is it Xeno?

Most likely the engineers had created xenos or something similar to them, like in the vases in contained material that could later result in the creation of something very similar to a xeno. Most likely a large amount of those xeno like things had gathered and slaughtered those engineers dragging them to that door. So speaking that the xeno like things created by the engineers turned on them and slaughtered them leaving traces of slime all over the pyramid/temple.

The slime came from a "reverse engineered" "bio-engineered" "bio-weapon" in adult form now dubbed the "Deacon".

Engineer tech is organic and the control panel was leaking after 2,000 years of no maintenance?

Some corrections guys. You got to REALLY pay attention to this film, almost nothing in it seems to be trivial. The goo is green, not black like the stuff in the temple, and not greyish white like what we see from Xenomorphs. It is green like that crystal thing in the Altar/ Control panel between the big stone head and the Embossed mural of the Xenomorph on what appears to be a door "This is just another Tomb" - Holloway and the door is round, egg shaped and has these things around it, that look a bit like the lips that open when an egg is about to fire out a facehugger. Anyway, back to the goo. Yes, David rubs it, then he stares at it. Then he SNIFFS it. Then he says to himself "IMPRESSIVE". Does anyone else think that the green crystal is some kind of control device that can keep the goo and the little worms etc dormant? I know that there are some suggested, superficially practical explanations for the room changing (nobody is wearing a helmet) and the worms may 'possibly' have come from outside on someones boot. But I don't think so. They appear to rise UP, INTO the footprint, and then submerge again. That suggests to me, that something awoke them from their slumber. And they HAVE been asleep for 2000 years, or else they would have eaten away that decapitated head, starting at the conveniently open neck. It's these two worms that become the space cobras. What do you think?

[i]Engineer tech is organic and the control panel was leaking after 2,000 years of no maintenance?[/i] It seemed that the marshmallow button could have been organic, but that panel looked like a touch sensitive stone plaque with "groove switches", no? It would be fascinating to know how the slime got onto one of the "grove switches". Was it on an escaping engineer's finger after having a struggle with a "deacon"? The device's purpose is that of a "recorder". It seems that if it was working right, you would see a holographic engineer standing at the device at the beginning of the recording.....unless, of course.....it is always recording and David had accessed the recording of the last movement in that section of the facility.

Does anyone else think that the green crystal is some kind of control device that can keep the goo and the little worms etc dormant?[/i] THIS is brilliant!!! You'd make an excellent detective. An engineer (possibly the one sleeping for 2000 years), sets all this in motion by dipping his finger in the green crystal to let the "bio-weapon" loose (thus we see the stack of bodies; all but 4: him and his 3 infected crew-mates carrying chestbursters). The recording shows 5 engineers (these 4 plus the 1 decapitated; but let's verify that). "Sneaky-geneir" turns the recording device on or off (not sure if it's before or after they run to the ampule room. 2000 years later, David gets green goo on his finger and enters the Ampule room. The room reacts to the green goo on his finger and the urns start leaking and reacting to his proximity to them like they're magnetized by his stinky finger (now called the "Dirty Sanchez"). ; ) [i]It's these two worms that become the space cobras.[/i] Minor correction, I saw 3 worm..... ; ) 2 to left of center and 1 over to the right. Plus, when we see them swimming, you can see more than 2 swimming, possibly around 5.

OMFG, OMFG! Ok, ok...Holy ****! This is developing into something CRAZY. This theory of mine. Now, REMEMBER this! THIS thread. GigerFace's thread on the Engineer's behaviour (should be his latest thread), the Deacon thread (Svanya's i believe). Are all going to converge for my next thread, and next theory. Just keep this all in mind. Yeah, with that said. WOW. Very nice. The Engineer letting things loose would support my idea of him going crazy, and just simply being a bad example of the species/a psycho. And DAMN! Abordoli, DAMN SON! DAMN, you NAILED it! Hence why there's 4 cryostasis pods! The Engineers who were supposed to be there in the first place, are dead. He just simply took one, since they all had a vacancy :D. But yeah. Like i said, look out for my next thread. I've got something fairly simple, but crazy being conjured up in my head in regards to the Progenitor Xenomorph ( i just felt like calling it that ).

I'll watch it again but it's hard to count how many engineers there were. First I thought only three, because it was so hard to count them running towards camera and we only see the last three running away from camera - 2 going in and one stumble, look back and then drop at the door. I don''t think that the guy just picked an empty pod of 4 available ones. Look at the actions of the holograms on the bridge. The walk in, bend to look at the pods. Three pods have holes above the chest area of the Space Jockey. Only one is intact. And they check it. Then they seem to discuss their 'lets attack Earth plan" and it seems that they all leave. It's all very weird. have to rewatch it. Now I know why the DVD release date is so viral.... we'll all be driven mad to buy it or go broke on cinema tickets... Antony, if you saw another worm off to the right then that means it almost certainly wasn't just careless humans dragging in worms to a bio-lab.

[i]Antony, if you saw another worm off to the right then that means it almost certainly wasn't just careless humans dragging in worms to a bio-lab.[/i] All 3 were under the foot impression as the foot was raised. I think the worms live there....not dormant....just indigenous to the temple floor area.

If they weren't dormant, why didn't they eat the head? Or do the sense the infection? What are they living on for 2000 years if they weren't dormant? I'll watch again but I think they rose up under the foot. Which suggests being roused (worms generally speaking would squirm away from movement, not towards it. And do you see the religious message in them being snakes... tempting Milburn. He says 'she's mesmerised' when it is HE that is mesmerised by her (reference to both the serpent and the female Eve)

I believe the worms were dormant for the same reason that the severed head was perfectly preserved. Low temperature, low to no humidity and absolutely no oxygen (the prime reason why things decay).

No oxygen? There is oxygen OUTSIDE in the hall, and when the door opened to let in the Space jockeys it would then be inside... unless we're assuming that theres a system that removes the oxygen. I find it odd that the door remains open after the humans leave, but not only does that enable Milburn and Fifield to re-enter, but if your oxygen idea, and my 'kill the intruder' idea are correct, then the door stays open to let the WRATH of the temple go get the trespassers. By the way, Milburn is the one to be attacked by the snake. He wears glasses. Levitius 21 prohibits people approaching the altar if they have a defect in their sight.

I would suspect that the altar room had a mechanism to remove the humidity and oxygen and reduce the temperature. Wasn't it already -22 F in the hallway. Fifield was snuggled in an aluminum blanket. I take it that the whole planet was on the cold side, thus filmed in Iceland to convey that.

I thought they said "minus 12" and didn't mention the scale. Minus 12 F is about minus 25'C. Do Americans still insist on using Fahrenheit in the late 21st century? Metric people!

Well that back to the slime, after seeing it a second time, it is smeared onto the control panel and only occupies a few of the recessed buttons in the bottom left corner. If the place went to pot (as Davids puts it) 2,000 years ago, that slime would have decomposed same as everything else in the hallway had, e.g. the decapitated body of the infected engineer.

...lest we forget that this is all alien technology, with properties unknown to us (intrepid crazy crew of bystanders). With that in mind, 1) the green ooze (I have seen the movie only once so forgives me) seemed like a deliberate result and not a causality, thus one of the Engineers might have set the room alarm when they exited. With materials that toxic to "any" living organism, not having a security protocol would be unhealthy.

I like it patch. Except after he sticks his finger in it, he enters the code to open the door in all buttons with no slime. Except David didn't need to touch the slime to open the door in the first place. (If I recall correctly)

Also note there is only slime on the controls that activate the holographic recording. There is not any on the controls that open the door to the ampule room.

While Celsius is nice because of its simplicity (i.e., the significance of 0 and 100), Fahrenheit (when using integers) provides higher temperature resolution in the range that humans live. Some might argue that one can add decimals (expand the number of significant figures) to the Celsius scale, but that becomes clunky and can be added to the Fahrenheit scale too, providing more resolution once again. While we are at it, kg isn't a measure of weight either, so you don't "weigh 30 kilos." [quote]Do Americans still insist on using Fahrenheit in the late 21st century? Metric people![/quote]
