Cerberus Retribution Quests on the Citadel

Last update: 29 October 2022

On this page of the Mass Effect 3 game guide you'll find the walkthrough for the Citadel Cerberus Retribution side quest. This walkthrough explains, among other things, where to eavesdrop on the conversation of the Citadel's inhabitants and how to behave during the meeting with Captain Sommers.

Received from: Ill-tempered civilians [Citadel: Presidium Commons]

Unlocked by: You will be able to start this mission after completing Priority: The Citadel #2 main quest.

This quest can be activated by finding ill-tempered civilians in [Citadel: Presidium Commons] near C-Sec.

Listen to the conversation between the civilians in order to find out that they want a revenge on a traitor that's being held in the prison. It's worth adding that you can find out about the traitor by overhearing other conversations in the Presidium area, however they won't unlock this quest on their own. Join in on the conversation and you should be able to hear a communication sent by Aaron Sommers, informing everyone that he plans to murder the prisoner.

Head down the stairs and enter a nearby C-SEC office. Captain Aaron Sommers can be found near the entrance and obviously you must talk to him. Sommers will confirm that the conflict is about a traitor that helped Cerberus units during the attack on the Citadel and now wants an immunity in exchange for his statements. This quest has four endings.

1. If you want to earn paragon points, then you can order Sommers to leave this place (upper right dialogue option) or talk some sense into him (special upper left dialogue option).
2. If you want to earn renegade points, then you can pretend like you didn't hear anything (lower right dialogue option) or force the C-SEC officer to hand over the prisoner (special lower left dialogue option).

The quest will end no matter how you've reacted, however it's important to know that both special dialogue options become available only if you've sufficiently developed your reputation.

Prizes for completing the mission:

1. [210 EXP]
2. [5000 credits]
