Objective 2: Disable the Security System

Area Secure

Wiping out the hoppers secures the upper ruins. Check your team’s items and gear if you haven’t done that recently, then make for the southern elevator. Climb aboard and ride the elevator to reach the next area.

Armature Bay Massacre

The elevator brings you to a wide armature bay. Step off the lift and advance down the short corridor that follows. Your radar soon becomes jammed, and a massive force of geth soldiers advance from the chamber’s northern end.

You face a number of destroyers and a towering geth prime in this difficult battle, so take no chances

Use your team’s most powerful abilities and concentrate their fire on the prime in an effort to drop him fast. Fall back afterward, if necessary, to give your team time to recover their abilities before making a second push.

The prime may have been the greatest threat, but you have many shock troopers and destroyers to deal with as well. Additional destroyers may be present at the far end of the bay, too. Keep alert and use cover as you make a final push to secure the area.

Opening the Archives

When the geth are no more, advance to the north end of the armature bay and move upstairs to access the bay’s elevated security room.

Activate the security panel you find there to receive a scrambled transmission that could only have been made by the Protheans 50,000 years ago.

Shepard isn’t able to learn much from the message, but it seems to be some sort of warning about the Conduit. No matter; the security system has been disabled.

You can now return to the Mako and pursue Saren into the archives. Head downstairs and use the elevator north of the security room to return to the upper ruins’ northern end, cutting down on travel time.
