In retaliation for recent losses, and perhaps hoping to regain the edge on the Alliance forces, Cerberus has attacked a major communication relay facility on the planet Ontarom.
Admiral Hackett needs Shepard on-site to secure the facility before Cerberus lifts valuable intel from the network.
There’s a catch: They are already in the system, and the only thing holding them back is a lone civilian operator who is in hiding—Grace Sato.
INITIAL CONTACT
As soon as you drop into the facility, Cerberus goes on the attack. Grace Sato puts up a nav point for you to follow to disable the hacking attempt.
Clear out the enemy first, as once you’ve killed all the Cerberus troops in the area, you get free rein of the facility to search for all the hidden items, as well as the Cerberus Codes for a side quest!
Cerberus Codes
The codes can be easy to miss. For reference, it’s near the second Cerberus Hacking Device you disable.
SECOND DEVICE
As soon as the first hacking device is disabled, Sato calls in, very worried that she’s about to be found out. Despite this, she puts up the location of the second hacking device. At the same time, Cerberus reinforcements swarm into the facility.
Fight your way over to it, clear the area, and disable it. Nemesis snipers are numerous here, so be careful.
It’s important to eliminate resistance before attempting each disable, as the enemy has the uncanny ability to interrupt you just before you finish the disable. Better to be safe than sorry.
FINAL DEVICE
Once the second device is history, Shepard calls Sato for the location for the last device but is met with fearful replies that she may be captured or killed if she keeps updating your team. How you respond to her will grant you Paragon or Renegade points.
With the final device marked on your screen, get ready to fight your way over to the central structure. The last device is located inside the building, in the circular central room.
You’ve got no real protection from attack from all sides, so bring your squad with you to keep the enemy busy while you go for the last device.
Phantoms can make an appearance here, so you definitely want someone watching your back, lest they kill you in a single stroke of their sword. With the last device disabled, your mission is complete.
