David

I read on the site today that an Alien rule book is being written possibly for future movies?

Yeah they can really go anywhere.

@dk - yes, I've read the same and think its a great idea to maintain the integrity of the canon.  If there is a set "rule" book then the canon can just carry on so long as there is a viable story line

Is it just me that finds it disappointing if it was David that killed the Engineer specie? Them going extinct because of a civil war would be more interesting. Maybe it could be alright if David killed many of them (he wants to be at the top of the ladder so to speak) but to make him responsible for all Engineers dyeing would be too much.

Thoughts_Dreams:I have a theory that it's possibly accidental.Chris observed that there's a water fall behind the Juggernaut,and also water flowing through it as well.If we assume that the Juggernaut that David and Shaw left had a payload of black goo(and it's a safe assumption)then it's likely that they crashed and the black goo contaminated the water.I've already said,in here i believe,that if the water is indeed contaminated,then it would likely lead to something akin to mass hysteria.The water of course work's it way into lakes,rivers,and eventually the ocean.It would then subsequently be absorbed into the atmosphere and be disseminated across Paradise via rain.Now imagine what a rain of black get contaminated water would to a civilization,first it would fertilize the world potentially creating the plants that cause the spores,but on the negative side the civilization would likely go mad and destroy itself.Imagine a world of Fifeld's just killing each other.
