Motivated by Tormuse's Video (thanks for those, they are awesome! :)) I decided to try this myself. After a handful of screwed up tries that mostly ended either on the way to Chained Court, at or quickly after the Anomaly, I got lucky enough spawns and enough med packs to beat this. Twenty Minutes is really a lot more time than you'd think. I was constantly worried that I'd run out of time, but was surprised in the end, that then run only took 11 and a half minutes.
PS: Kudos to the RNG for dropping the ballistic vest which helped a lot with Cybie :)
PPS: Yay promotion! :)
