Wow, tokamak. It appears you have thought a lot longer about this than I have.
Expanding on the Brink Universe
Air cities? Taken by Bioshock: Infinite 
No, just kidding… Anyways, that would be a wee bit too high-tech I think, but this is 120% fiction, so if they could do it back in 1800+, then why not in the 2040+? 
… Would rather have ships and other things crash into the Ark full of cargo, or maybe drifting ships with… Cargo the both factions want and fight over them
*Or the big-ass ships that fights with eachother / internally for resources
… We got some weird ideas, don’t we
Well, because tokamak have more post than anyone here. It’s show how intelligent he is (no sarcasm), it’s more a praise
Yeah I have a topic about this, and I don’t remember exactly what was said it never got too popular. But! once they realize that people are playing the crap out of this game, there will be DLC. I mean c’mon it’s bethesda lol.
