How to complete the Arc Raiders Harvester puzzle
The Harvester in Arc Raiders is a massive drop pod of resources that sits under the Arc Raiders Queen. It contains blueprints and large quantities of loot, but it's booby-trapped and will alternately burn or electrocute anyone inside if the puzzle isn't solved.
Enter by prying open the doors or via roof vents, and wait for any fire to die down before going in. You must find three fuel cells — steel objects you can carry in both hands. One lies on the floor, the other two are behind access panels on the upper walkway. Bring all three to the central terminal, pry open the ports and plug them in; the ports may close periodically, so keep the cells close to the terminal to plug them in quickly.
When the cells are plugged in, yellow nodes appear on the walls; shoot and destroy all of them. The nodes retract for the fire trap, which also ejects the fuel cells, so you'll need to plug them back in each time. Once every node is destroyed the traps deactivate permanently and the central terminal opens, granting access to the loot.
