Last update: 29 October 2022

This page of the Mass Effect 3 game guide offers a walkthrough of the N7 side quest - Cerberus Attack. This walkthrough explains when to explore a Cerberus-controlled military facility, how to regain control of an artillery cannon, and how to defend yourself against Cerberus forces.

Received from: Specialist Traynor [Normandy SR-2: Combat Information Center]

Unlocked by: You will be able to approach this mission after completing Priority: Sur'Kesh.

You should be informed of the possibility to begin this mission by Specialist Traynor after you approach her on board [Normandy SR-2: Combat Information Center]. She will tell you that it would be good to examine the old military plant on Tuchanka which has been taken over by Cerberus forces.

For that, use the galaxy map and head to the Krogan DMZ. After getting there (Aralakh system) and fly to planet Tuchanka. If you haven't completed the main mission connected with this planet, make sure you're chosen Cerberus Attack.

Listen to the conversation with Admiral Hackett and start exploring [Tuchanka: Cerberus Attack] to regain control over the large artillery gun. Head towards the building with the control panel. On your way you will of course come across Cerberus forces and you should most of all attack them from behind covers. Nothing complicated here, though you should look out for the Guardians, Centurions and Engineers. Also be sure to keep an eye on the left side, as enemy force can also come from there.

Keep fighting until you eliminate all of the Cerberus soldiers. I'd suggest exploring the whole area, especially that it won't take you much time. You will find, among other: spare parts [3000 credits] [3500 credits], the [Armax Arsenal Gauntlets], Med Kit [100 EXP] and the Old Grid Schematics (needed for Citadel: Improved Power Grid).

In the end try to use the control panel. It will end with failure, as the Cerberus forces will cut off the power supply.

A new battle awaits you, this time of the defence kind. I'd suggest placing one team mate by one of the windows of the control room and the second by one of the passages located at the back of the hall. Shepard himself should change his position frequently and not let enemies reach the room.

Especially look out for Nemesises - Cerberus snipers - as even one hit can cause serious damage. Try to watch what your enemies are doing and head where you will be most useful.

After initially cleaning the area, head towards the two marked power modules. They should be guarded by Cerberus Troopers who won't be too much of a challenge. With each of them, you first need to destroy the lock and then interact with the device [150 EXP] [150 EXP].

The last part of this mission implies returning to the control room, though you will be faced by numerous Cerberus units in this case as well. Many elite units will take parts in this battle, so it would be good to create an alternative plan of reaching the destination, for instance by following one of the passages in the back. Regardless of the chosen option, look out for the Nemesises and don't let the enemies surprise you.

Once again interact with the control panel, this tie destroying the enemy ship [450 EXP]. In the end hear out a conversation with Hackett.

Prizes for completing the mission:

1. [10000 credits]
