This mission is acquired from Specialist Traynor after the Cerberus assault on the Citadel. It is acquired through dialogue aboard the Normandy.
Landing EditJacob Taylor will be present and be injured in the firefight; if not, a stand-in character named Dr. Webber will be hit instead. After Shepard clears the initial pad area a conversation ensues. Jacob will vouch for Shepard, but in his absence, the refugee leader, Dr. Brynn Cole, will be mistrustful due to Shepard's past ties with Cerberus, forcing you to engage three more Assault Troopers before she'll let you in.
You may talk to Jacob Taylor on entry and investigate into what's happening. At the right, you can talk to a grieving doctor for some reputation points. Dr. Gavin Archer may be present at the top of the first flight of stairs, depending on your actions in Overlord, and reminiscently you may notice the Overlord music playing when you fight your way to the satellite tower soon. Meanwhile you will also find a datapad with 2,500 credits, and another datapad with some insight into some of the research being done. Through the door is an Assault Rifle Magazine Upgrade and a Weapon Bench. Up the stairs and through another door is a medical station.
Upon talking to Dr. Cole, Shepard will also be alarmed by the discovery that some of the scientists brought their families with them. Jacob/Dr. Webber will inform Dr. Cole that the installation's roof-mounted anti-aircraft guns are offline. But first things first, take the time to explore Dr. Cole's base.
On the top floor is a datapad, another datapad with 2,500 credits, a microscope that triggers a comment from Shepard about a poison designed for turians, another datapad about the work they were conducting, and a Shotgun High Caliber Barrel mod behind a crate near the door to the next area. You can also talk to Dr. Brynn and listen to the others for more information.
In the medbay you can find the Kassa Fabrications Greaves on some crates by the door, a datapad with 1,250 credits, another datapad from Jacob about the AA guns, a medical station on the wall, and you can talk to Jacob if he's present.
Satellite Control Area EditM-6 Carnifex on the pipe to the left if you don't have it already. When you come around the corner, there are guards facing the wrong way, but they're standing near a Shield Pylon, so if you want an ambush you'll need to snipe the Pylon, hit both guards with a Chain Overload/Energy Drain, and then finally start shooting (alternatively, if you can get a Scorpion round to stick to the shield pylon, its explosion should take out the pylon and both guards near it). It might be easier to just do a stand-up fight. Either way, continue up the raised platform to find another Combat Engineer guarding the satellite control area.
Note: This Combat Engineer sabotaging telemetry controls cannot be damaged until he turns around to acknowledge you. (But he can be put in Stasis, at least with the Bubble)
Reinforcements will jump down to join him, and if you can place a Singularity under them, you'll win without breaking a sweat. Pick up the SMG High Caliber Barrel behind the crates on the left after the drop down.
Tip: Note that after eliminating the Cerberus forces but prior to actually activating the button to repair the dish, you can first turn around climb back up onto the next section and destroy all the shield generators and collect all the loot against no resistance all the way to the turret, as the enemies will not spawn until you actually repair the dish. You can then return to the dish, repair it and the shields you took down will remain down, making the next section considerably easier and allowing you to complete it without stopping to collect loot along the way during active combat.
Once you restore the controls, Jacob or Brynn will tell you that the AA guns still need to be activated. Next to the controls, a Med-kit and a Datapad worth 2,500 credits can be found.
Turret and AA Towers EditSniper Rifle Piercing Mod that can be found behind the large containers near the ladder to the right tower. This ladder is broken, so make your way up the left tower. Activate the AA gun and move across the crosswalk to the adjoining platform.
On the second AA tower is a Datapad containing 3,750 credits, a Med-kit below the datapad and a turret, down the ladder is a Shotgun Spare Thermal Clip. Climb back up and activate the second AA gun to discover it requires repairs. Assign the squad member of your choice and head quickly to man the turret. On the other AA tower and on the platform below Cerberus shuttles will deploy troops including the highly evasive Phantoms; use the turret to obliterate the opposition. Shuttles will land a trio of troops at the first AA gun station and down on the roof where you just fought, which is on the gun's left side; said troops descend very slowly, so that's the best time to snipe (or "turret") them. Once all enemies are dead, return to the AA gun console and activate it.
Once evacuation begins, Cerberus troops crash through the sky lights, and you have to fight them. Dispatch the three troops in the upper area and head down to dispatch the three troops on the stairs.
When the hangar doors open there are several troops to battle, as you move forward Cerberus shuttles drop more troops on the raised platforms. Be sure to disable the generators supplying the enemy with barriers, or at least shoot the three shield pylons. Eventually Cerberus will drop an Atlas Mech. Jacob/Brynn pilots a shuttle tasked with picking up Shepard. Destroy the Atlas and the ending cut-scene ensues.
It is notable that Jacob survives this mission regardless of his previous loyalty; there is actually no way to kill him off over the course of this game.
Upon completion of this mission, you will gain 12,500 credits and adds Ex-Cerberus Scientists and Dr. Brynn Cole to your War Assets. If Jacob is present, he will be recruited as a War Asset as well, and can later be interacted with at Huerta Memorial Hospital. Finally, you can also gain Dr. Gavin Archer as a war asset provided you satisfied the following conditions:
- Completed the Overlord DLC missions in Mass Effect 2.
- Successfully rescued the Grissom Academy students before this mission.
- The evacuation cinematic bears a strong resemblance to the evacuation scene in Star Wars: The Empire Strikes Back - In both scenes, ground-to-air defenses are used to clear a way for the escape craft, and the evacuation is also cut short by the arrival of enemy troops. Some of the dialogue options are almost direct quotes from that sequence.
