I recently purchased THE BOOK OF ALIEN reprint and found the section that Paul Anderson talks about in the recent Fangoria. Originally, there was supposed to be a pyramid near the area where the Nostromo crew landed on LV-426 (it was obscured by the dusty winds but was revealed once the weather settled). Once inside, the crew finds mysterious hieroglyphics that detail the Alien life cycle. There is an actual Giger painting featured in the book that shows these markings, images that include the Space Jockey creatures using themselves as sacrificial hosts for the Aliens. I assume that they worshipped the Xenomorphs at one time. If they do make a fifth Alien somewhere down the road, I hope they answer some of the questions we have about the Jockey's. By the way, that's my AVP report over at Game Gossip. Lance was a pretty cool guy but he didn't really give us any new info other than telling us about the surprise ending (which makes me a bit nervous). The footage that they screened for us was just the new trailer and the two internet featurettes.
