To save Miranda in Mass Effect 3, she must have survived Mass Effect 2 with her loyalty mission done, you must warn her about Kai Leng and give her Alliance resources, and you must stop Henry Lawson from shooting her in the standoff at the end of Priority: Horizon. Miss a step and she usually dies after that fight.
The steps run across most of the game, and several are easy to skip, so here they are in order.
The Steps in Order
| Step | When | What to do |
|---|---|---|
| 1 | Mass Effect 2 | Keep Miranda alive through the suicide mission and complete Miranda: The Prodigal |
| 2 | After Priority: Palaven and one more mission | Meet her at Bay D24 in the Citadel Docks |
| 3 | After Priority: The Citadel II | Read Anderson’s Kai Leng message at your private terminal |
| 4 | Soon after | Warn her during the Spectre Office call |
| 5 | After Priority: Perseus Veil | Meet her in the Presidium Commons apartment and give her the Alliance resources |
| 6 | Priority: Horizon | Pass the reputation check, or take the Renegade interrupt, in the standoff |
Do all six and she lives, and she stays available for the Citadel DLC.
Step 1: What You Need From Mass Effect 2
Miranda has to survive the suicide mission, and you need to have completed her loyalty mission, Miranda: The Prodigal. It also helps to put the right people in the right roles.
A new Shepard with no import cannot save her. She always dies on that save.
Steps 2 to 4: The Citadel Meetings
Bay D24. After Priority: Palaven and one more mission, she emails you to meet at Bay D24 in the Citadel Docks. If you miss it, she emails again. Go anyway, since it sets up the rest of her story.
The Kai Leng warning. After Priority: The Citadel II, Anderson sends you a dossier on Kai Leng. Read it at your private terminal before the Spectre Office call that comes up in the Citadel Embassies, usually one mission later. If you have read it, Shepard warns Miranda during the call automatically. If you take the call first, the warning never happens.
Order is the whole point here, so check your terminal as soon as that mission ends.
Step 5: The Apartment Meeting
After Priority: Perseus Veil, she invites you to a meeting in an apartment in the Presidium Commons. She asks for Alliance resources. Give them to her.
Refusing or skipping this meeting is another way to lose her. If you romanced her in Mass Effect 2, this is also where you commit to that romance. Our romance guide covers that side.
A romance detail worth knowing: don’t break it off with her on camera during Mass Effect 3. A breakup carried over from Mass Effect 2 is fine, and so is having locked in someone else before this scene.
Step 6: The Standoff on Horizon
At the top of Sanctuary in Priority: Horizon, her father Henry Lawson is holding her sister Oriana hostage, and everything comes down to this one conversation. Save before you enter the final elevator.
| What you do | Result |
|---|---|
| Pass Charm or Intimidate | Henry lets Oriana go, and Miranda kills him |
| Fail the check, and take the Renegade interrupt | Shepard wounds Oriana in the leg to distract him, and Miranda kills him |
| Fail the check, and take no interrupt | Miranda kills Henry, but he fatally wounds her |
If your reputation is not high enough, watch for the interrupt. It is your backup, and it saves Miranda as long as you did the rest.
What Happens If You Miss a Step
BioWare never published the exact rule, and we could not settle whether the warning and the loyalty mission are each required on their own. Do every step, since none of them costs you anything.
If she dies, it happens after the fight with Henry. She may still reveal what she found before she goes.
| What changes | How much it matters |
|---|---|
| Her war asset | You lose about 25 Total Military Strength |
| Priority: Horizon’s story | Continues either way. A squadmate finds what you need if she cannot |
| Citadel DLC | Her scenes and her spot at the party are gone |
| Her romance | Ends with her death |
If Miranda died back in Mass Effect 2, she does not appear at all, and Hackett finds the Cerberus base’s location instead. The main story never stops without her.
Oriana’s fate depends on Miranda too. If Miranda is at the standoff, Oriana lives. If she is not and you take no interrupt, Oriana and Henry both fall.
Frequently Asked Questions
Does Miranda always die in Mass Effect 3? No. She lives if you complete all the steps above. She only always dies with no import or if she died in the suicide mission.
What if I did not do her loyalty mission in Mass Effect 2? Plan on losing her. Her survival is tied to it, and you cannot do it from Mass Effect 3.
Do you need to romance Miranda to save her? No. Romance changes her scenes, not her survival.
When exactly should I warn Miranda? There is no dialogue choice. Read Anderson’s message at your private terminal after Priority: The Citadel II and before the Spectre Office call, and Shepard does it on their own.
What is the reputation check on Horizon? Charm or Intimidate in the standoff with Henry. If you fall short, the Renegade interrupt does the same job.
Should I give her the Alliance resources? Yes. Denying or skipping the request is a way to lose her, and it costs you nothing worth keeping.
