Will have to look into this.
Wonder if its close to a Story i working on over a year ago that i had basic Synopsis and ideas for but i then failed to finish as far as actually detailed book.
My book was going to be Alien: Unearthed or Alien: Ascension
Basically a World a group of W-Y employees about the time of Alien had gone to, in order to Mine for Minerals etc, they detect some kind of Material they have not discovered before, potentially a new Metal Element.
So they begin to set up shop and start to dig near a Volcano, then we have a incoming ship with more recruits to help and they get there just as the others lose contact with some workers.
They go in and find dead bodies, they go further in and find a cave system and the ceilings and walls have like Spores in them, kind of like a Honey Bee Hive as far as Holes in the Walls that contain Spore like Cocoons like Gremlins and some of these are then hanging from a like slime and a tendon...
One of these then falls and opens up to reveal a Octopus like Face Hugger, They latter encounter Aliens that are different to in Alien and more like a bit like unused Newborn from Alien R crossed with similar to the Prometheus Fresco
They find also Engineer dead body, long dead.
They try to blow up this cave, and it then causes a Earth Quake and it reveals a Buried Derelict they explore it and awaken a Engineer who then kills some of them and a Alien and then he gets Face Hugged and we get a Alien thats similar to the Prometheus Fresco.
They then escape after trying to blow up the Derelict and it then causes a Volcanic Eruption once again burying the place.
It would have been ambiguous a bit to tease...
"i wonder if this is where they got Face Hugged by some organism that leads to the Frescos in Prometheus, and they then Re-weaponized and experimented on this.
So it was my attempt to maybe explain the Xeno origin but in way that only teases a I WONDER IF and not to exactly say this is what came first.
It was left ambiguous to why the Engineers was there...
To collect the Organism?
To mine for Ore that they use in their Technology and found the Organism?
Oh it was not set on LV-426... but a place far away.. i had not figured yet what the Worlds was called or how far away but i was thinking a good 200LY maybe more and it would be set between the years 2125 and 2145
