ARC RAIDERS / GUIDE
Queen / Harvester minigame
Get past the Queen, insert three fusion cores and clear the yellow targets inside the Harvester.
Find the active Harvester
The Queen guards the Harvester; the puzzle happens inside the structure. Look for the Harvester map condition on Dam Battlegrounds, Spaceport or Blue Gate. Opening the enemy briefing below explains the Queen fight separately. Our advice: decide before deploying whether your goal is the puzzle or fighting its guardian.

Prepare your approach
You do not have to defeat the Queen to start the puzzle. Watch her patrol, then approach a ground-level vent. Smoke, a or a can help you reach cover. Bring healing, shield recovery and ammunition for the targets. Before breaching, identify a way back outside; entering without an escape plan makes the fire cycle much harder.

Collect three fusion cores
The essentials
Breach containers upstairs to find the puzzle cores; the wiki also records one on the central floor.
In practice
Bring three to the lower level before starting the insertion sequence.
Shared location callouts
Our advice: stage them where you can reach them, and have squadmates call out which core they are handling instead of everyone searching the same container.

Load the central pillar
Open the chambers around the base of the central pillar and insert all three cores close together. Be ready for a shield-draining electrical surge and a brief stun. This is a different hazard from the fire purge: do not assume every alarm means the same thing. Check your shield charge before continuing.

Clear yellow targets and escape the fire
Shoot the twelve glowing yellow targets exposed around the interior. The fire warning uses sound and yellow lighting; leave through an open vent immediately rather than finishing a reload. Fire can eject cores, requiring reinsertion. Clearing a whole target group preserves its corresponding core through the purge. Use the warning cues rather than relying on a memorised timer.

Loot, then return safely
Finishing the sequence opens the central reward containers. and are associated with this puzzle; inspect the actual loot before planning a craft. Our advice: cover the exits while a teammate searches, protect important finds in safe pockets where possible, and leave enough raid time for extraction. The Queen and other Raiders still make the trip home dangerous.
