I wasn't trying to read previous comments but I can't help but notice the same similarities and possibilities of this fitting Terminator, too.

I also have a love of things gone dark and depressing.

And while I don't mind having an ending that is happy or hopeful, rising from the proverbial ashes and whatnot, I don't mind a sad, hopeless, unhappy ending :) So I can't help but wonder what path your story takes - where it came from or where it's going - and it sound cool :)
