Citadel (Citadel under attack)

Mass Effect 1 (Legendary Edition) guide · After Virmire

Shepard and the Normandy crew assault the Citadel after Saren uses the Conduit to bypass security, bringing Sovereign into the heart of the station. You must fight through geth and krogan forces along the exterior of the Citadel Tower to reach the Council Chambers. Once inside, you confront Saren, disable the docking clamps, and determine the fate of the Council and the Destiny Ascension.

Enemies

Geth Shock Trooper

Weak to Overload, Tech and Biotic abilities

Standard mid-tier infantry encountered along the tower exterior.

Geth Rocket Trooper

Weak to Tech abilities, Sniper Rifles

Fires high-damage explosive rounds from range along the exterior walkways.

Geth Destroyer

Aggressive heavily shielded units that charge your position with shotguns.

Geth Prime

High-tier heavy unit armed with heavy weapons and deploying combat drones.

Krogan Battlemaster

Weak to Biotics, Warp, Toxic/Incendiary damage

Extremely durable vanguard equipped with shields, shotgun, and health regeneration.

Saren Arterius

Weak to Overload, Warp, heavy automatic fire

Mutated biomechanical husk that moves rapidly, clings to walls, and fires rapid-fire energy bolts.

Tips

Equipping Tungsten or Shredder rounds (depending on whether you are fighting Geth synthetics or Krogan organics) dramatically speeds up fights along the exterior.
When fighting the mutated Saren, keep your squad spaced out to avoid mass knockdowns from his wall-pounce leap attack.
Biotic abilities like Lift or Singularity can temporarily hold Saren and heavy Geth units in place, disrupting their powerful shield regeneration.
You can use Charm or Intimidate dialogue options during the final confrontation with Saren in the Council Chambers to convince him to commit suicide, entirely skipping his first combat phase.
