The Citadel is now in orbit over Earth, in the heart of Reaper-controlled space. A final assault on Earth is the only way to deliver the Crucible to the Citadel and defeat the Reapers. Launch the assault on Earth when ready.
Paragon/Renegade
You can convince the Illusive Man of his own indoctrination, after which he ends his own life (by either shooting himself or by storming directly into your line of fire).
This is actually a series of Paragon/Renegade persuasion options that get progressively harder. To complete the final persuasion successfully, you must have used a persuasion on the Illusive Man in every one of your earlier conversations—on Mars, Thessia, in the Illusive Man’s base, and the three previously in this conversation.
Final Upgrades
This is it. The last chance to get upgraded weapons, mods, or reassign powers before the end of the line. Stop by the shuttle bay if you want to make any last-minute purchases, or visit the medical bay to reassign powers. There’s no turning back here.
