Key Choices and Consequences-Mass Effect Wiki Guide

Final edit:

On this page, we only list the choices that have “main” and “medium” effects in “Mass Effect 1” and/or its sequel, and have been divided into these two parts and arranged roughly in chronological order. Options that only have a small impact (such as resuming an email) are not listed.

caveat: Needless to say, yes Heavy The spoilers on this page are not only Mass Effect 1, but also 2 and 3. This page will list the choices and your choices, and then detail the consequences of each choice in the “destroy box”. Read at your own risk.

There is no need to meet Garrus Vakarian at the Med clinic to complete the “Castle: Expose Sari” mission (but this requires meeting and recruiting Urdnot Wrex). If this is the case, after you expose Saren and become a ghost, he will wait for you outside the central C-Sec elevator. Here, you can decide whether to recruit him:

Recruiting Gallus

Ignore Gallus

Recruit Wrex


There is no need to meet Urdnot Wrex at the Med Clinic to complete the “Castle: Expose Sari” mission (but this requires meeting and recruiting Garrus Vakarian). If this is the case, after you expose Saren and become a ghost, he will wait for you outside the central C-Sec elevator. Here, you can decide whether to recruit him:

Recruit King

Ignore Rex

One of your early tasks is to search for Liara T’Soni in the Artemis Tau cluster. Her response to you may be very different, depending on whether you have completed multiple mission worlds before pursuing her.

Find Liara after Feros and Noveria

After Virmire, look for Liara

Felos: The fate of the colony

In this important mission, you can complete secondary missions, use charm/intimidation to persuade Fai Dan, and use special grenades to help ensure the survival of the colony. Then, based on these actions, the fate of the colony is determined through survival checks.

Closing the colony

Novaria (Noveria): The Rachni Queen

At the end of the Noveria Mission series, you will meet Rachni Queen and must choose whether to forgive her or let her escape, or kill her with acid.

Keep Queen Rachni

Killing Queen Lacini

Finally, the DLC’s “Let the Sky Come Down” mission has an important decision. You must choose between keeping the hostages and letting Barak drop or sacrificing them, or sacrificing them in order to attack Barak.

Save the hostages

Attack on Barak

In the early days of “Virmire Mission”, you will learn that Saren found a way to cure Genophage in the laboratory, and Wrex is angry about it and thinks it will be destroyed. You have to face him face to face on the beach to find a solution.

To persuade Wrex to stand down, you need to earn 8 Charisma points or complete the “Wrex: Family Armor” mission to unlock the necessary options to save him. Otherwise, you can shoot him yourself, and if you told her to “be vigilant” earlier, you can order Ashley to shoot him, or you can’t find a solution that caused Ashley to kill himself.

Rex Life

re die

Virmire: Kaidan and Ashley

At the end of Virmire, you will have to choose to rescue Kaidan or Ashley, who will be at the bomb site or AA tower (who is where depends on the person you assigned to the Kirashi team before the attack).


Sharon dialogue about Vermeer

At the end of the “Vermeer” mission, you will have an in-depth conversation with Saren in the ally with Sovereign. Finally, you will have a “survey” option on the left: this marks an important final choice for when Saren appears.

If you select “It has already happened!” or “You have been indoctrinated”, you will open the persuasion options, which will take effect later in the game.


The last Shalin conversation

In the last conversation with Saren, you can choose to persuade him to resist the Reaper implant. This requires 12 points for the “Charm” or “Intimidation” attribute, but if you select the “Charm/Intimidation” option on Virmire, you only need 9 points. If you can’t, you must choose “This is meaningless”.


“It makes no sense”

Destiny ascends

During the mission, after meeting Saren, you will have to choose whether you want to order an alliance fleet to save your destiny, or ignore it and focus on sovereignty.

Save destiny promotion

Focus on sovereignty

Human Committee

Through your actions in the final mission, you will be able to choose the human senator who will join/lead the castle council between Udina and Anderson.


Interestingly, you did not really remember this choice when saving Mass Effect 1, because the game will not be saved afterwards.When saving and importing “Mass Effect 1” to “Mass Effect 2,” the system will ask you for this choice and the selected object in advance There Will be reflected in 2 and 3.

When you rush into Chora’s study, you can choose to kill or exempt the owner Fist. This can be up to you or Wrex can do it automatically because he was hired to kill Fist.
