How to unlock the The Sacrifice achievement in Warframe - Definitive Guide

I struggled at a few points during this quest so I figured I'd post a quick reference for anyone who is a warframe noob like me.

Firstly, in order to even start The Sacrifice, the "Personal Quarters" must be built in your foundry. This opens a room in the rear of your ship. Approach the window and interact to play through the intro.

At one point you will be tasked with cracking an Orokin Cipher. Simply find the markings on the walls around you and they will light up. Once you've found them all, return to the cipher and input those symbols. They should be hovering above the cipher at this point directing you which symbol should go into which slot.

A few times throughout the quest you will have to fight/stun Umbra. To do this, transfer out of your frame to your tenno/operator. Use RT to remove his shields. This can take awhile, try running around, using LB, etc to escape and let your RT recharge. Once his shields are down, use the melee attack (B) to stun Umbra. This move is a bit tricky to land, I had more luck in close range. Immediately after stunning Umbra, press RB to use transference into the Umbra warframe.

You will also need to defeat multiple Sentients/Mimics during the questline. The best strategy for me was to use my primary weapon until the enemy became resistant. Then use transference and shoot them with the operator's void beam (RT) to remove/reset their resistance. Then transfer back into the warframe and repeat the process. I tried to utilize cover whenever possible and lure the Sentients/Mimics into 1-on-1 combat whenever possible.

Anyone who plays a decent amount of warframe probably won't have much trouble with this quest, but since there wasn't anything posted here I figured I'd add a few tips. Cheers.

Wow, this quest was annoying.. fighting Umbra with the Operator was just stupid! A few notes--If you climb up high enough Umbra can't attack you while you're in Operator form(or Warframe), you have to be like 4-8 Warframes high for that to work. Then you can just transfer to Operator, and shoot Umbra as he runs around down below. Worked way better for me than getting constantly stunned/killed by Umbra.
I used Valkyr as was mentioned in the comment. That worked great, especially getting the full energy recharge when they die! Best thing to do is combine Warcry with Hysteria I think, and then switch to Operator super fast, shoot the Sentient, then switch back and see if you can keep your melee streak going.

The final battle, vs. the Sentients, I found that Radiant Howl? worked great for stunning the Sentients then I would blade them to death, using Radiant Howl as often as necessary. I discovered this after wasting quite a few minutes running around with the Operator...

Just helpful tip that worked for me towards Sentients and Mimics, I used Valkyr Prime, a normal Valkyr warframe will work just as good, since her fourth ability, Hysteria, makes you invincible until you run out of energy. Also, when these enemies to die, the drop something that replenishes all of your energy.

FYI on the Sentients:

Ash's Blade storm can two hit them with ease. And, if people tuned into the stream last Saturday, you should have a free Ash Prime coming your way.

I have done almost every quest in this game with Ash simply because he makes things a bit easy to burn through laugh. Loki is good too, but only if you are looking to avoid most enemies.

It takes more than adding the Personal Quarters to start this quest. You have to complete Chains of Harrow which will then cause an image of Lua to appear near the window. That kicks off the short quest Apostasy Prologue which then allows you to start The Sacrifice in the regular quest list.

A huge tip for people on this quest, make sure you join The Quills in Cetus. Get the Amp for your operator. Make sure you level the amp up a few times before taking on Umbra the 2nd or 3rd time. Made it a lot easier for me.

To begin The Sacrifice quest you will need to have completed The War Within, Chains of Harrow and Apostasy Prologue.

Go to your Codex and pick the quest then head to the Lotus' helmet in your personal quarters and touch it. First part head to Earth where you will be fighting Grineer Ghouls. You will need to defend a door against Ghouls, you will then need to use your scanner on the sword, and 3 Warframe parts. One is located to the right of the sword just down the buried stairs, another is on the side where you entered the area behind a rock and the last is a cloth hanging off a rock opposite side of the helmet. Head to the Exit.

Check you foundry then head to Lua for the second mission vs Sentients. Head to the waypoint then look for marking on the wall. At the next waypoint you will need to find more symbols. Enter the are and look for a interactable object on the ground to the left when you enter the area and click on the blue enemy symbol. Head to the exit.

Insert the new ship part then build Excalibur Umbra and equip the Warframe. Head to Ceres for the next mission vs Grineer. You will need to void blast him in Operator mode with then enter with the . Play the game with Ballas then exit the mission.

Head to Neptune for the next mission. You will have to kill Mimics. Fight vs Umbra is a bit more annoying as you need to drain his shield with the void attacks then stun him with and enter with the again. Fighting Umbra in operator mode is annoying if you don't have an upgraded Amp, what I did was Void Dash down the long side of the balcony then attack him as he comes to you then void dash back to the other side and repeat.

Head back to Lua to confront Umbra. Take his shields down with void attacks then blast him with and enter with the again. Walk down the path. When you return you will be using the Excalibur Umbra, defeat the Sentients then end the mission.

Head to Earth to confront Ballas. Defeat the Sentients and the quest will end.

In order to open the quest, you need to complete the quests The Second Dream, The War Within, The Chains of Harrow, as well as the “secret” Beginning of Apostasy - interact with the blue energy ball in the warframe’s room.
