Citadel: The Final Battle

1. Secure the Crash Site

When you barrel through the Conduit relay and crash directly into the Presidium courtyard, inspect the area beside your overturned Mako to collect the Crash Site Med Kit near the corner of the floor light. Move toward the elevator while keeping your distance from the three Husks that drop from the Dragon's Teeth spires, taking advantage of biotics or Anti-Personnel rounds to knock them down before their electrical explosions reach you. You can talk to the glitching Avina terminal standing alongside the walkway before you enter the lift, which abruptly cuts power to force your squad into the maintenance section.

Tip: Use abilities like Throw, Lift, or Singularity to kill the unshielded Husks immediately before they close in.

2. Breach the Maintenance Shaft

Step into the dimly lit corridor of the Citadel Tower Maintenance Shaft just as a derailed tram car smashes straight through the tunnel wall. Use the natural bottleneck created by the wreckage to eliminate incoming Geth Troopers, Shock Troopers, and Snipers from comparative safety. When the charging Krogan Warlord pushes forward with his shotgun and Immunity, lock him down with Damping, Lift, or Warp to prevent him from regenerating or reaching melee range, then ascend the ramps at the end of the hall.

Tip: Funnel the advancing geth forces directly through the gap opened by the derailed tram car.

3. Push Across the Exhaust Plain

Move out onto the sheer exterior skin of the tower along the Citadel Tower Exhaust Plain while weaving between sweeping red kinetic energy barriers. Fight your way through the entrenched Geth Troopers and Snipers while a Geth Dropship deploys fresh enemy squads overhead. Locate the three Citadel Defense Turret consoles along the surface—triggering Citadel Defense Turret #1 with its manual override, Citadel Defense Turret #2 via Average Electronics or 20 Omni-gel, and Citadel Defense Turret #3 via its manual switch further down the path—to automatically shred both the dropship and ground targets.

Tip: Activating the defense turrets is the fastest way to wipe out the Geth Dropship and clear the plain.

4. Clear the Exterior Defense Grid

Step onto the fortified exterior walkway, immediately utilizing long-range sniper fire or Assassination from the corridor threshold to take out the four heavy exterior turrets before their explosive ordnance pins you down. Halt the simultaneous assault of the Geth Juggernaut, Geth Destroyer, and two charging Krogan Warriors by cycling strong crowd-control powers such as Singularity, Stasis, or Lift. Once all defensive forces are cleared from the trenches and barricades, pass through the airlock hatch and elevator to access the Council Chambers interior.

Tip: Stay back at the entryway threshold to pick off the fortified turrets before tackling the heavy infantry.

5. Confront Saren at the Council Console

Enter the devastated Council Chambers and advance past the rubble and shattered central stairway toward Saren Arterius at the main terminal. You can attempt Charm or Intimidate persuasion checks to break him out of Sovereign's mental grip, causing him to thank you and shoot himself in the head to skip Phase 1 of combat entirely; otherwise, you must engage him on his hover glider by hiding behind barricades and stripping his defenses with Overload and combat talents. After Saren is down, interact with the master terminal to override the station arms, prompting Joker to ask over comms whether the Fifth Fleet should save the Council and Destiny Ascension at high cost, or let them perish to focus all firepower directly on Sovereign.

Tip: Passing the Charm or Intimidate dialogue checks completely bypasses the Phase 1 hover glider fight.

6. Destroy Sovereign's Cybernetic Avatar

Face Saren's resurrected Cybernetic Avatar as Sovereign takes direct control of his mutated corpse inside the Council Chambers. Keep moving constantly across the floor to avoid his lethal explosive beam attacks, high-speed wall leaps, and melee rushes, tracking him with continuous weapon fire whenever he scales the pillars. Weaken his defenses with Warp, suppress his tech offenses with Sabotage or Damping, and blast through his health to overload Sovereign's shields, concluding the battle so you can recommend either Captain David Anderson or Ambassador Donnel Udina for the human Council seat.

Tip: Track the avatar with Sabotage and Damping to shut down his tech attacks, and apply Warp to burn down his heavy damage resistance.

The short version

What matters

• Activating all three defense turrets on the Exhaust Plain to instantly eliminate ground troops and the Geth Dropship.
• Investing in Charm or Intimidate to convince Saren to shoot himself and skip the entire first combat phase.
• Deciding whether to sacrifice Alliance ships to save the Destiny Ascension or focus solely on Sovereign when Joker radios in.
• Choosing between Captain Anderson and Ambassador Udina to represent humanity during the ending sequence.

Common mistakes

• Rushing past the Presidium crash site into the elevator without looting the missable med kit resting by the floor light.
• Running blindly onto the Exterior Defense Grid walkway instead of sniping down the four explosive turrets from the entryway.
• Staying pinned in one cover position during the final boss fight, allowing Sovereign's avatar to crush you with leaping melee charges and explosive beams.
