With the pieces of Rosetta returned, Isaac, Ellie, and Carver can now finally assemble the Codex. This missing link should allow them to interface with and shut down the Machine, and ultimately, destroy the Necromorphs forever.

Tau Volantis Rosetta Lab
Arrange Rosetta at the Sample Array
The Rosetta experiment requires the alien samples to be arranged in the correct order. But this creature is an Alien—how am I supposed to know what it looks like? I suppose I should figure out which are its head and feet, then work my way to the middle.…
As you return to the Rosetta lab, you find that all nine samples are in the array. Unfortunately, the are not in the correct order. It is your job to put the puzzle back together.
Like a puzzle, you need to figure out which pieces connect together—even if you don’t know what the final product will look like. Start with the feet. You can tell that you have the bottom sample since it has no cutaways on the left side. Pick it up with kinesis and move it to put this piece at the end farthest away from Ellie in the control booth.
Next find the top of the head. It is the sample that has no cutaway on the right side. Put it at the end closest to Ellie. Now, starting with the feet, look at the cutaways on the right side. Then find the sample with the same shape of cutaways on the left side. Move it over next to the feet. Continue doing this until all of the pieces are in the correct sequence.
Once all of the samples are arranged in the correct order, the array automatically brings them together. Now you must walk over to the console on the side of the room and activate a switch to assemble the samples into one alien.
Together as Once
Reassemble Rosetta to earn this award.
Rosetta is not a person. It is an alien. The scientists used an alien brain to create the Codex. Now that it is assembled, all that remains is to activate the Rosetta experiment to understand the Machine.
As Rosetta is being decoded, Isaac sees a vision in which a Marker erupts into final Convergence, sucking the aliens up into the sky, their bodies forming the Necormorph moon of Tau Volantis.
Isaac now understands what has occurred. Tau Volantis is not the Marker homeworld. The aliens were drawn to the planet. The moon is the source of the signal, not the Machine. The moon is the Convergence. The aliens built the Machine to freeze the planet to keep the moon from becoming whole. If the Machine shuts down, everything thaws. The Convergence continues—not just here, but everywhere the Markers have spread. The Codex is the key.
Just as Isaac figures it all out and stands up with the Codex, he realizes that Danik has entered the lab. His soldiers have taken Ellie and Carver captive and he has a gun on you. Danik takes the Codex and plans to use it to shut down the Machine so that Convergence may continue.
Just as Danik is about to have you all killed, Isaac hits a button on the control panel that activates the sterilization gas to begin sanitizing the lab.This creates an opportunity to get away from the soldiers.
The gas will kill you just like it did the soldiers, so get out of the lab as quickly as you can. Your suit is no protection against this sterilization agent. Carver is waiting for you at the door.
As you get to the door, it is stuck. You have to help Carver close it manually. Ellie is not able to get out. To survive, you have to close the door and get out.
Retrieve the Codex from Danik
All the linguistic data for communicating with the Machine has been downloaded to the Codex. But now Danik has it, and he’s going to use it to shut down the Machine. But we were wrong: The Machine isn’t creating the Necromorphs—it is preventing them from spreading! Shutting down the Machine will initiate Convergence. I must get the Codex back!
The gas is spreading throughout the entire floor. Follow the locator beam to the elevator as you run to escape the gas. Once you get to the elevator and take it down to the lower level, you are safe from the gas. Advance through the hallway to the door that leads to the Geology sector.
Catch Up with Danik
Danik has a head start, but I’ll do whatever it takes to stop him. This is what Ellie would have wanted me to do. She will not have died in vain.
Follow the locator beam toward the steel walkway. As you get there, laser sights light up the snowy haze. Fire at the source of the sights—even though you can’t see the soldier holding the weapon. Advance along the walkway, engaging soldiers as you go.
Keep going to the clearing with the storage containers. More Unitology soldiers are here. Take cover and open fire. Watch out for grenades thrown by the soldiers. Move away from them and keep up the pressure. In addition to the soldiers, you also have to deal with Stalkers that attack both sides freely.
Clear out all the enemies here, then move to the cargo lift and take it up to the upper clearing. One of Danik’s gunships arrives and begins firing at you. Run for the gatehouse that is lit up by flames. Kill the soldiers inside and then continue through a door into a small room.
The small security room contains a couple of centuries-old corpses as well as a flame glaze weapon part. Pick it up and then exit through the other door to another clearing with several crates.
As you move out into the clearing, you are attacked by several Super Slashers as well as Unitology soldiers who are up on catwalks and firing down on you. Some rappel down to the clearing and attack from the ground.
Take cover and return fire. Clear out the enemies at your level, then go after the soldiers up on the catwalks.
Once it seems clear, rush across the clearing toward the door. It is locked. However, you don’t have time to worry about this now. More soldiers up above start firing down on you. As if that were not enough, Twitchers attack you at ground level.
When all the enemies are dead, unlock the door by using the electrical engineering interface next to the door. Now move through the door and follow a frozen corridor toward another door to continue to the next chapter.
