This side-mission can be found by entering the Normandy’s galaxy map and having the ship travel to the following location:
Eagle Nebula > Amun > Neith.
Scan the planet and locate the anomoly to begin the mission.
Once you land, look to your right and behind the shuttle to find a canister of Refined Platinum . Continue around to the other side of your shuttle and set a course for the flames you see burning in the distance. On the way you will find an object on the ground - System Status Report . Examine this, and then look to your right and go to the wall to find salvageable mech parts . From here, continue towards the fire, and look out for the canister of Refined Platinum against the left wall. Instead of continuing towards the fire, follow the left wall all the way around the central rock island to find the navigator’s log and another canister of Refined Platinum (there is also some salvageable mech parts a little further past the platinum against the right wall if you missed them earlier).
Turn around and resume towards the flaming wreckage. In the middle of the area you will find the evacuation order, a Med Kit and a shipping manifest. Head over to the right-hand wall and follow it around the corner for a salvageable damaged mech and another canister of Refined Platinum . Continue up the nearby ramp to find a box of Power Cells and a security report. When you are ready for a fight, use the transmitter.
Activating the transmitter will cause a small army of LOKI Mechs to spawn in the area below your current position and in the previous areas leading back to your shuttle. Make your way back to the shuttle and use the right-hand path around the circular rock island in the center of the region. You will need to eliminate 15-20 LOKIs and a YMIR Mech on the way. When you reach the shuttle, you can use it to leave the area even if hostiles are still on the loose. Doing so will end the mission.
