Priority: Rannoch

Priority: Rannoch is a Mass Effect 3 mission on the quarian homeworld Rannoch. The Reaper base that controls the geth has been found but is shielded by jamming towers, so Shepard lands and uses a prototype targeting laser to let the Normandy destroy it. The geth are freed from Reaper control, but the quarian fleet keeps attacking them, and Shepard must moderate between Legion, who wants to upload the Reaper code to the geth, and Tali. Depending on the choice the quarians or the geth are wiped out, or, with a high enough Paragon or Renegade score, the two achieve peaceful coexistence and both fleets join the war effort.
