This mission is acquired automatically after Cora Harper: Asari Ark.

## Walkthrough

This mission involves combat in different rooms of varying sizes. Bring a well rounded set of skills and weapons to handle short as well as long distance combat.

Be **VERY** careful of fires and burning items in this mission. These are not interesting background animations but actually very dangerousHEAT HAZARD - Hazard Level 4 zones that will immediately deplete life support and then kill Ryder.

### Read e-mail from Cora

An e-mail will arrive from Cora Harper after this mission is acquired. Head to the Tempest to read the e-mail from Cora.

If Ryder heads directly to talk to Cora instead of reading the email, this objective will fail but there are no consequences for doing this.

### Speak to Cora on the Tempest

Find Cora on the Tempest and speak with her after reading the email. Cora will inform Ryder about the location of the Ark Leusinia in the Valay system.

### Search the Valay system for Ark Leusinia

Head to the Valay system and use the Tempest scanner to find an anomaly that turns out to be the Ark Leusinina.

Ryder can approach the ship and bring up a prompt to accept the mission. This is the last chance to back out of this portion mission before being locked in for the duration. Once Ryder is ready, accept the mission and select the loadout.

### Dock with Ark Leusinia

This objective completes automatically after the landing cutscene ends and is not shown on screen.

### Reach the bridge

Ryder and the squad will arrive in a hallway with overturned containers and items strewn about.

* Starting Hallway

There is no combat in this entire section of the ship and Ryder can head forwards towards the closed door. Open the doorway into a large room that has suffered damage.

* Entry Room

Ryder can scan multiple Debris and Banners in the room but they do not award any Research Data (RD).

Ryder can approach a closed and locked door on the other side of the room and over the comms Elonis Atandra threatens to open the airlocks and kill the intruders. Ryder convinces the captain that they are here to help and Elonis calls off the depressurizing sequence.

The doorway will then unlock and Ryder can head into the next area. There is a Navigational Holodisplay that Ryder can scan but it doesn't award any RD.

Continue into the Atrium where evidence of of a battle and fires are still burning. There are additional Debris and Banners that can be scanned but none award any RD.

* Atrium

There are two datapads Leusinia: Crew Complement and Status Report: Leusinia to read in this area.

There is a closed door at the other side of the Atrium. Open the door to reveal a small hallway that heads down and then back up a set of staircases. This leads to another closed door. Opening the door starts a cutscene and this area can no longer be interacted with after that.

A cutscene will start where Ryder will talk with Sarissa Theris and Elonis Atandra. They will inform Ryder what has been happening and why the Ark is so damaged. Kett have boarded the Leusinia and are below decks wreaking havoc. The drive core is offline and the only way to leave is to get power restored. Ryder volunteers to go and help the asari commandos below decks to restore the power.

### Ride the tram to Hangar Control

After the cutscene, Ryder will appear in the tram and can interact with the tram terminal to reach other parts of the Ark.

### Look for asari commandos in Hangar Control

The tram doorway will open to a small hallway with a closed doorway. Open the doorway to a long hallway that leads into the Hangar Control. In the hallway there is a datapad Hangar Control: Maintenance Log to read.

* Hallway to Hangar Control

Head into the Hangar Control and speak to Vederia Demali to learn about the problems with the Hangar Bay. Ryder will have to close the hangar door by overriding a console.

* Hangar Control

### Activate hangar door override

Explore the area first before approaching the override console to understand the layout of this area. The Hangar Control has a lower and upper area. Locked doorways on the upper area will open allowing enemies to spawn during the hack. Enemies will have the high ground around the area that Ryder will have to hold while the hack is taking place. There are a single set of ammo, health, and power cells supply caches right near the hack zone. There are more Debris that Ryder can scan but they don't award any RD.

There is a small zone around the override console that Ryder will have to stay inside for the hack to proceed. There will be a set of white circles on the ground indicating where Ryder has to stay for the hack to work. Leaving the hack circle will stop the hack process and will only continue when Ryder returns to the circle. Enemies will continuously spawn in groups while the hack is taking place. Some enemies will enter the zone while the others from the upper level will fire upon the squad. The goal is the endure the attack while the hack is taking place.

Approach the Hangar Controls console and activate it.

### Defend the hangar override console

Enemies will spawn and an onscreen progress bar will indicate the **Hangar Door Closure Sequence** and the white hack circles will appear. Defend the hack zone until the hack is complete.

### Eliminate the remaining kett

After the hack is completed, defeat the remaining enemies in the area.

### Speak to Vederia

Before heading to Vedari, resupply as needed with the supply caches and explore the area. There is a container in the upper area.

* Container 1

After collecting any items, speak to Vedari in the lower area of the Hangar Control. Closing the hangar door has had some unforeseen consequences resulting in an electrical overload and fires have broken out. She suggests Ryder head to the lower decks through the living quarters while she heads off to check on the stasis pods.

### Go below decks through the living quarters

Vedari heads through a doorway that now locks and the other doorway in this area will unlock for Ryder. Open the door that leads to hallway with a staircase the descends to another closed door. There are Debris that can be scanned in this area but they don't award any RD.

* Hallway to Living Quarters

Open the door and head into a very dark room. There is a series of staircases that lead down to dark area with a closed door the living quarters area.

* Lower Dark Staircases Area

At the bottom of the staircases, there is a datapad Evacuation Orders and a container to collect.

* Container 2

There are some large green boxes in the corner. These Cages that can be scanned for +10 Heleus RD. Scanning one Cage turns the others light yellow.

There are some Debris in this area as well but scanning them doesn't award any RD.

After Ryder has finished collecting items in this area, head to the closed door and open it to enter the living quarters.

* Living Quarters

The living quarters is a series of interconnected corridors and rooms. The main path forward is blocked and so Ryder will have to take the long route around the obstructions.

There are Debris in this area as well that can be scanned but they don't award any RD.

There is a Broken Door that can be scanned for +10 Milky Way RD.

Head to the northern corridor as this is the only unobstructed path to take.

* Northern Corridor

There is a closed door on the right as Ryder heads down the corridor. Open the door and head into the first room on the right.

There is a First Aid Station that can be scanned for +10 Milky Way RD. There is also a container in this room.

* Container 3

After collecting items in this room, head back to the corridor and continue to another room with a closed door, this time on the left side. Open the door and head into the second room on the left.

There is a datapad Color Fun For All Ages! on the table. There is a terminal with two entries: Re: Childcare rotation and Goodbyes!. There is a container to collect.

* Container 4

There is a PERSONAL LOCKER #43556 - J. T'KINA that can be scanned for +10 Milky Way RD. There is also a PERSONAL LOCKER #10034 -Q. SIRINIS that can be scanned for +10 Milky Way RD.

After collecting items in this room, head back to the corridor and continue to another room with a closed door, this time on the right side. Take care, if Ryder walks too far down the corridor and out into the larger dark room, there will be a growl out of the darkness and two Wraiths will surprise attack while cloaked.

Open the door and head into the third room on the right. There is a terminal with two entries: What's Happening and Re: Regrets. There is a container to collect.

* Container 5

There is a Weapon Storage that can be scanned for +10 Milky Way RD. There is a PERSONAL LOCKER #95884 - N. MATHERA that can be scanned for +10 Milky Way RD. There is a PERSONAL LOCKER #11093 - S. THERIS that can be scanned for +10 Milky Way RD.

After collecting all of the items in this room, head back to the corridor and continue into the very dark room.

* Ambush Area

As mentioned before, an ambush attack is coming. Prepare Ryder for the Wraiths that will come out of the dark southern corridor and defeat the enemies.

After combat, head to the southern corridor as this is the only unobstructed path to take.

* Southern Corridor

There is a closed door on the right but move past this door and continue down the corridor to a closed door on the left. Be prepared as there are enemies in the room. Open the door and defeat the enemies.

After combat, there is a large container to collect.

* Container 6

There is a Ration Crate that can be scanned for +10 Milky Way RD.

After collecting the items, return back to the corridor and to the closed door that Ryder had previously moved past. Open the door and enter the room. There is a set of supply caches of ammo, health, and power cells in this room. Resupply as needed and head to the closed door in this room. Open the door and head into a corridor with pipes.

* Pipes Corridor

There are multiple curved pipes in this area. Ryder can scan the Maintenance Pipes for +10 Milky Way RD. Scanning one of the pipes will turn the rest light yellow.

Head to the closed door at the end of the corridor, open the door, and continue towards the Fire Control area.

* Corridor to Fire Control

It is very important to understand that in this corridor, the fires on the ground are very dangerous. These are level 4 heat hazards and deal serious damage. Carefully avoid the flames on the ground, especially in the lower staircase area, as they are hard to see and it is easy to walk into them on accident.

* Lower Staircase Flames
* Flames Corridor

Carefully move through the flames to the closed door at the end of the corridor. There are a number of Debris to scan along the way but none of these award any RD.

Past the closed door, there are enemies waiting. Prepare for combat and when Ryder is ready, open the door into the Fire Control area.

### Secure Fire Control

Defeat the enemies in the Fire Control area. Be very careful as there are multiple fires in this area that are just as dangerous as the enemies. Be aware that there is an upper area where enemies will spawn and jump down into battle.

* Fire Control

There are multiple supply caches in the area to resupply during combat.

Defeat the enemies.

### Reactivate the fire suppression system

After combat, the area is still very dangerous due to the fires and exploration should be paused until the fires are out. Head to the Fire Suppression System console. Ryder can scan the Fire Suppression System for +10 Milky Way RD. Activate the console but be prepared for it to electrically overload and do damage to Ryder's shields.

### Scan for a way to reroute power to the fire suppression system

After the failed attempt to reactivate the Fire Control System, Ryder can scan the ground to find yellow wires that lead to the Fire Suppression System override panel. Carefully approach the panel as there are dangerous fires in this area. Ryder can scan the Power Junction for +10 Milky Way RD. Activate the override to reset the main console.

Despite what the objective says, scanning isn't what completes this objective. Ryder has to complete the override for the objective to complete.

### Reactive the fire suppression system

After completing the override, head back to the Fire Suppression System console and activate it to put out all of the fires. This also puts out the fires in the prior corridors as well.

### Meet Vederia

Ryder can now explore the area without the danger of fires. There are Debris in this area that can be scanned but don't award any RD. There is an upper area of Fire Control that can be accessed by carefully jumping up on a ledge on the wall and then jumping up onto upper area. There is a set of supply caches in this area but nothing else of interest.

Resupply as needed and then head to the now unlocked door. The door will open automatically into another room.

* Room After Fire Control

Ryder can head towards another door that will open automatically leading to a corridor. Head into the corridor and there is an Armor Maintenance Station that can be scanned for +10 Milky Way RD.

* Corridor to Observation Deck

Continue along the corridor to a set of supply caches. Resupply as needed. There is a room nearby with a door that will open automatically. Head into the room and there is a terminal with two entries: Evac and Security. There is a datapad Scratch Pad on the desk. There is a large container that always contains a leveled  Asari Sword.

* Container 7

There is Workshop Equipment that can be scanned for +10 Milky Way RD.

After collecting the items, head out of the room into the corridor and go back to a staircase that goes down to a door that automatically opens into the Observation Deck.

* Doorway to Observation Deck

Head to Vedari who is standing next to a large device. Speak with her to learn that this strange device is what is draining all of the ship's power. This cobbled together device has to be turned off but she doesn't know how to. She asks if SAM can analyze the device and find an answer.

### Scan the mass effect field device

Scan the Mass Effect Field Device for +10 Milky Way RD. SAM will inform Ryder that shutting down the device requires two people to complete. One person must disconnect the device while the other is disconnecting the power cables.

### Disconnect power cables (0/3)

Ryder now has to approach three different sets of cables to disconnect them. Before starting this process, take the time to explore the observation deck and familiarize the area without the pressure of combat. There are multiple supply caches of ammo, health, and power cells on two different levels in this area.

* Observation Deck

The process that is about to take place requires disconnecting a power cable and then killing off all of the kett that spawn. This process will take place three times.

When Ryder is ready, approach a Power Cable and scan it for +10 Milky Way RD. Ryder can then interact with the power cable to disconnect it. When the cable is disconnected, enemies will spawn.

### Eliminate the kett on the Observation Deck

Defeat all of the enemies that have spawned from disconnecting the cable. This objective will complete and will return after each cable is disconnected.

Ryder can now resupply. When ready, approach the second cable to repeat the process of scan, disconnect, defeat the enemies, and then resupply. Repeat the process again for the third cable.

### Disable the mass effect field device

After all three cables are disconnected, there is a single container to collect.

* Container 8

Head back to the Mass Effect Field Device and turn it off.

### Get to Deck Twelve

The mass effect field will turn off that is holding the hull plating sealing a giant hole in Deck Twelve. The plating will fly off into space exposing a hole to kett boarding ships.

* Hole in Deck Twelve

Kett dropships will approach and drop off enemies in Deck Twelve. Ryder can now approach a closed door at the other end of the Observation Deck and open it into a small corridor. There are supply caches near another closed door. Resupply as needed.

### Optional: Trigger mass effect field

SAM will inform Ryder that the Mass Effect Field Device is still active and can be triggered once during the upcoming battle.

Before heading through the closed door into Deck Twelve, it is important to understand what is about to take place during this final battle:

* Combat will begin when the Ryder opens the door and enters Deck Twelve.
* There are three levels in this area. Ryder starts on the lowest level and there are staircases up to the second level. There is a third balcony level that Ryder can jump up to. However, the third level doesn't appear on the map.
* Audio will be highly distorted to approximate the area being exposed to space. This makes it much more difficult to hear auditory cues.
* Enemies will fly in from dropships in three waves. After each wave is defeated another set of enemies will fly in from dropships for another wave. The third wave of enemies will also have The Valiant appear. This is the final boss of this mission.
* The optional mass effect field will effect the local gravity of Deck Twelve. It isn't explained what will happen but Ryder can trigger the field one time and it will cause all of the current enemies in the area to be sucked towards a glowing mass effect field. The enemies will be spun around the glowing spot and then the field will explode throwing enemies back down onto the deck. This gives a pause in combat, damages the enemies, and throws them into disarray allowing the squad to take advantage. This doesn't affect The Valiant however, only normal enemies will be affected.
* There are supply caches on all three levels to resupply as needed during combat.
* There are no containers in this area.
* There are Debris that can be scanned but they don't award any RD.
* If Ryder wants to collect any remains, this must be done before the final enemy is killed because a cutscene starts immediately at the death of the last enemy.

When Ryder is ready, open the door and head into Deck Twelve to begin combat.

* Deck Twelve

### Repel the kett attack on Deck Twelve

Defeat all of the enemies and a cutscene will start.

Sarissa will attempt to defend the hole in the side of the ship with a biotic sphere after The Valiant orders the kett ship to fire every weapon possible at the Leusinia. The sphere will not be large enough to block the incoming missiles. She calls out for help from Cora and the two of them are able to extend out the field much larger. This destroys some of the missiles and reflects others back at the kett vessel doing significant damage. This allows the Leusinia the time it needs to engage the drive core and jump to safety.

Ryder and the squad will appear on the bridge with Sarissa, Elonis, Vederia, and other asari. Cora is distraught about how Sarissa stole the kett data and let Matriarch Ishara die. She is very conflicted because she looks up to Sarissa as a role model but at the same time her recent actions were reckless causing great harm to the ark. A conversation wheel choice will appear to either *We should keep this quiet.* or *The asari should know.* This conversation choice determines which asari will become the pathfinder.

* Keep it quiet - Sarissa stays the asari pathfinder. Cora will be very conflicted but will get over it. Sarissa will show up to help with the final battle on Meridian.
* Tell the asari - This option allows Ryder to another conversation choice to choose who the pathfinder will be:
	+ *She'll be fine.* - Vederia Damali becomes the pathfinder. Cora will be troubled about the recent events and need time to process but she will get over it. Vederia will show up to help with the final battle on Meridian.
	+ *Keep Sarissa as Pathfinder.* - Sarissa stays as the pathfinder. Cora will be very conflicted but will get over it. Sarissa will show up to help with the final battle on Meridian.

After the pathfinder has been decided, Ryder returns to the Tempest and speaks with Cora. The conversation will change depending upon the conversation choices during the mission. Cora will reflect upon her prior feelings of Sarissa and how recent events have changed them.

The mission will then end after the conversation and the final rewards will be given.

* +1330 XP
* Cora's Rank 6 Skills unlocked
