Ok, I am a HUGE Alien fan. I even have the very hard to get Colonial Marines Technical Manual sitting on my bookshelf and I've read the entire thing, cover to cover, more times than I can imagine. I've seen Aliens more times than any other movie. Needless to say I'm really looking forward to this game, and will likely enjoy it a great deal when it comes out, but some things are nagging me.
SPOILERS for those who haven't seen the movie or the trailer, read at your own risk.
OK, so, we clearly see a video feed from Hadley's Hope. Theres just no way thats possible. Hadley's Hope was only home to roughly 300 people, and the shots we see in the movie and other sources put it as a very small community. The Atmospheric Processor was practically next to the colony. There is just no possible way ANY of Hadley's Hope survived a thermonuclear detonation of that magnitude. Even if it did, theres no way any video feed would be working. If we go off of the tech manual, the derelict ship would have survived the explosion however, which makes it plausible that if anybody went down to salvage anything from the colony or the Sulaco, there is a chance they became infected.
Next, this is iffy given the fact we know little about how they actually work, but would the air on LV-426 still be breathable after the detonation? I'm assuming they are going off of the assumption that there is still some breathable air left before the entire planet reverts back to its initial atmospheric conditions.
Very unlikely that Bishop's legs would be found, they would have been blown out the airlock. Still, some chance that maybe they got stuck behind something.
No mention of the events of Alien 3 yet and that has me wondering a bit. The Weyland-Yutani knew exactly where the EEV was, and where it crash landed. The Marines should have the same ability to track it. This makes me wonder if we are going to see Fury 161 in the game at some point.
