When to start
After Priority: Tuchanka
“Admiral Hackett has requested assistance with a Cerberus fighter base on Noveria. Land on Noveria to disable the base’s defenses.”
Advanced Fighter Squadron War Asset
To start Cerberus Fighter Base, locate Horsehead Nebula, east from the Citadel, in the Milky Way. Enter the system, then travel to Planet Noveria. Land and customize your team and weapons to begin.
Watch the small cutscene and get ready because the Cerberus troops will wait for you. Swiftly clear the landing area, and you will be asked to reach the command center.
On the second floor (where you landed) reach the passage on the left side, and near a ladder which allows you to go down, you will find some spare parts you can salvage for 2.000 Credits.
Continue to follow the corridor near the ladder, and advance. Go down the stairs and to the right you should see some chairs. Pick up the Pistol Magazine Upgrade, and open the Medical Station near the chairs.
Additionally, examine the Comuter Console in the same chamber, then follow the next stairs down, and go right.
On a desk to the right, are more Spare Parts you can salvage, and a Datapad on the left side of the Command Center.
On a wall, next to a door you will see another Medical Station. While facing the station, turn left, and up on a wall, next to a display, are the Heating Unit Schematics.
This important item will help you complete the Heating Unit Stabilizers Citadel Mission.
Get them then deactivate the Security Console. Assign one of your crew members to complete this task. Protect your team-mate, then fight your way to the landing pad (starting area).
When you reach the extraction point, an Atlas mech will wait for you. Take it out using your favorite strategy, and leave Planet Noveria.
Next N7 mission is: Fuel Reactor.
