Is the door to the Dining Room welded shut too? Or unlocked as per the plan?<br/><br/>Do the stairs go down as well as up, or just up?<br/><br/>I'm going to RP it so the sentries can work at 100% efficiency in the fog, it seems a logical design feature - no frickin' facehuggers crawling along the floor under there for me!<br/><br/>Oh yeah, how many people lived on the colony please Urban? In Aliens there were I think 158 on LV-426. Given those sorts of numbers and given that this is the only Hab Block you've told us about I'd say there has to around 20 dwellings per side and tiered two levels high for a total of 80 dwellings. If each is the size of a very minimalist apartment (kitchen, bedroom, shower room, lounge - some would need 2 bedrooms) that makes the Hab Block a pretty big space. You could assume other quarters elsewhere for senior personnel or even two dormitories somewhere for single males and single females... so we could go with smaller than 80 dwellings - maybe as few as 40, still quite big. Its not a problem I just want to think this through for the setting up of the sentries.
