What kind of environment mechanics does the space station have? Is there any way for players to screw with the air, water or gravity? Where does the food come from besides new players? Can the ai control station systems?
I don't know what coded systems are in place for things like atmospherics, and if they can be dicked with or not, there are certain locations (like engineering) I can't access as my character has clearance for the research labs as he's a scientist, not an engineer. However, once you get into the game you'll notice that there are both pipes and power cables coded in, these are badly damaged in some places, and you can try to repair them or in some places rip them up... I've gleaned from within the game that when the first people woke up all the lights were working and the place was generally in good repair, but either they or something else ripped the ship (sorry if I say station it's a force of habit, but as far as I know this is a space ship not a station) up a bit, certainly it caused the issue with lighting and the damage to wires.
The resources in terms of wires and pipes and other repair materials seems more or less exhausted, unless there's a huge cache in engineering. I know metal is needed, and the engineers ask people to make sure to give them the empty tins after they eat rations. By the way, most random crap can be used in crafts, though you may not see that if you don't have the craft skills needed to have an item in your craft list that uses them, but if you do and you EXAMINE an object it'll tell you if you 'realise' that it can be used in a craft you know. But there are people walking around with cook-pot helms, tin-can pauldrons, serving-plate shirts, and many variety of duct-tape-enhanced clothing or weapons... it's pretty amusing and awesome all at the same time.
As for rations, other than the AI which gives them out to new players, the only other source is corpses, and apparently some sort of factory on deck 2, they try to send teams up to gather rations when they can, but the last one ended in a lot of death the moment they stepped out of the elevator and other (Hidden Fun Stuff) which forced an immediate retreat.
There is apparently no lighting on up there, but there are machines, not sure what they all do other than the factory which produces (or delivers) rations. There are a number of things you can build/fix/use, such as cameras, traps, even remote droids... though my knowledge of the ins and outs of that is very limited due to my more science focused skill-set. But I know they try to scout deck 2 using some sort of droid that was refurbished, and there are cameras around, though many are just static right now which suggests wherever they are they're broken, and one is in perpetual darkness (I imagine it's some place on deck 2, and I'd actually be able to see something through it if I looked when there was a team up there with lights.)
As for the AI, I have /very/ limited knowledge of its capabilities, I am assuming it's manipulated by the staff only and isn't a player or an active coded AI. I know in some event that it sealed off an area that got broken into from deck 2 by the stuff that is up there that's eating everyone's faces off, but that's the limit of my knowledge. There's some sort of religion springing up around the Ship though (and presumably the AI that runs it) among the survivors, the head of that movement may know much more.
