Mass Effect 3 Walkthrough – Part 21 – Geth Drednaught – Renegade – HD 720
Shepard meets with Qurians who have apparently begun a war with Geth in order to take 
back their home world. The Reapers have assumed some amount of control over a majority of the geth using a code broadcast from a nearby Geth Dreadnought. Tali, newly made an admiral, is going with Shepard to disable the signal from the Geth Dreadnought. It seems that Legion is on board and a prison, being used to amplify the signal to the “new machines” as the old ones are fully under Reaper Control
