This side-mission can be found by entering the Normandy’s galaxy map and having the ship travel to the following location:
Titan Nebula > Haskins > Capek.
Scan the planet and locate the anomoly to begin the mission.
After landing, make your way into the clearing housing the entrance to the factory. As you approach the door, a pair of FENRIS and LOKI Mechs will emerge. Dispatch them and enter the door. Head into the open room in front of you to find a Med Kit, computer and a hackable wall safe. After picking them all up, return to the corridor and enter the unlocked door at the far end.
Continue forward along the small walkway to the right and when you are spotted, eliminate the pair of FENRIS Mechs. Once the two of them are dead, take cover behind the railing to the left and use it to eliminate the LOKI Mechs (around 10) that appear in the room below attempting to reach your location. Once they stop coming, turn around and pick up the canister of Refined Element Zero nearby before cruising round the corner and down the ramp to the room below.
This area is a little confusing as the room is littered with cargo crates. There are two main passageways that will funnel you through the obstacles here. First, head all the way to the left wall and fight your way through four LOKI Mechs to reach a box of Power Cells .
Return to the ramp you climbed down and this time, head all the way to the right; as you approach the corner, a large contingent of LOKI Mechs will find their way over to meet you and there are around thirty of them, but they only come solo or in pairs; they will continue to come until you have defeated them all. Move through the crates until you are forced to turn right. Again you will need to defend yourself against a flood of rampaging kill bots (this time only ten or so!). Once they have all been disabled, move forward and look at the end of the first small passage to the right for a canister of Refined Element Zero . Climb the ramp at the end and enter the door.
After opening the door, look behind the crates to your left for a canister of Refined Element Zero before climbing the ramps to the top and opening the door. Hit the production line shutdown console in the corner to complete the mission.
