All that still doesn't necessitate that the colony was completely destroyed. It would depend on the seismic activity caused by the blast, and the strength of the blast as it was detonated at ground level, I think. Plus the colony had sub-levels, and it would ultimately depend on how well the colony itself was constructed. It was obviously made to endure a harsh enviornment, maybe colonies are very hardy and well built? They certainly look that way, with the layers of support beams lining almost all colony walls, extremely durable soundproof (and nearly shatterproof) glass, and other safety features. There could have been emergency safe rooms for the colonists, but they didn't or couldnt access these rooms during the xenomorph invasion for reasons unknown...
I mean, when the (dumbass) colonists first settle the planet, the atmosphere isn't breathable, and with Acheron's harsh weather you'd think any living complex would have to be extremely well built to be safe. It would also originally be an airtight environment, though it didn't need to be in Aliens as the atmosphere was breathable.
Sorry for nerd rant, I just think the story will probably be better than the Alien and Predator things we've seen in the past few years.
and I'm excited. As a writer I think revisiting Hadley's Hope is gutsy, could easily be bogus and end in continuity disaster, but if they are smart about it, it could also work. The Derelict has got me peeing, just a little. I feel that this game could help redeem the Alien, at least. Bring it back from the dark velociraptor cat days.
Anyway I think the game sounds incredible, with the lighting and dynamic AI, these both make me very happy. Sounds like the sentry gun may be a mini game? Definite purchase already, can't wait for epic 4-player Aliens moments dying with my friends
. Die motherf**ker.
