FOUND Specific fic search: Stony + aliens

[devaccumulation.livejournal.com]

It was a comic-verse fic, somewhere on AO3, rather long, featuring dominantly Steve and Tony, but also many people from the comics cast (Hawkeye, War Bird, Hank Pym and others). Aliens had taken over the earth and captured Tony (though he had supposedly surrenedered) and were forcing him and several other scientists to reverse-engineer their technology, as they had to flee from their mother planet and left their technicians to die. Steve was leading the revolutionaries. Clint went undercover to help Tony and the scientists were dying because the aliens didn't give them anything with salt and citruses in it (though not on purpose). There also was some power fighting among the aliens. Please help?
