(Missable)
Mission – Rannoch: Geth Fighter Squadrons
Acquisition - Automatic after disabling the geth dreadnought.
This is the easiest mission that you will find. There is no combat and you’ll have no trouble getting through it. It is an important mission story wise, though. All that you have to do is destroy the glowing sections of the reaper virus and free data clusters.
Note: Be sure to finish this mission before starting Priority: Rannoch.
