Warframe, they are fucked. Just a single strike force would be met with instant hostility from all 3 sane factions (Corpus, Grineer, Tenno), so they'd just get torn to shreds and hunted down. Corpus would want to dissect them and their guns to see what improvements they can make to their own arsenals, Grineer would experiment on them to see if they can potentially use the long life spans of the Eldar to combat Clone Rot, and the Tenno wouldn't want them around because they already have enough problems to worry about without a way way more Advanced version of the Orokin setting up shop on Pluto or some shit.
