ARC Raiders is filled with many secret locations that require solving complex puzzles. The Blue Gate map is home to a series of locked doors filled with advanced ARC parts and other valuable loot. To open these, you'll need to carry fuel cells and slot them in fuse boxes to open the doors and claim their loot. This guide will provide you with all the locations for these puzzles and how to open them, whether solo or with a team.
Ancient Fort Puzzle
The Ancient Fort area has three batteries you need to carry to three separate fuse boxes to open the basement doors.
- The first battery is in the ruined building west of the fort, marked by a small signal tower. Carry this battery to the fuse box on the outer southern wall of the fort.
- The second battery is in the second ruined building northeast of the fortress, on a toppled shelf. The fuse box is located inside the fort on the second floor.
- The last battery is inside the fortress, in the room with a hole in the ceiling, and is found just under the yellow cloth on the wall. The fuse box is inside the watchtower at the top of the fort, next to the ladder.
Once all fuseboxes are powered up, head to the basement doors next to the fort to claim your loot.
Raider’s Refuge Puzzle
This is easier to do than the Ancient Fort puzzle, as you don’t need to carry fuel cells. You must interact with 4 switches hidden in the Raider’s Refuge area.
- The first switch is right next to a generator to the left of the locked door.
- The second switch is on the other side of the church, where you got the first switch, behind a wooden bench.
- The third switch is on the church's broken rooftop. It's tucked away underneath the wooden beams at the southwestern corner of the rooftop.
- The final switch is inside the church, to the left of the yellow generator.
Deforester Husk Puzzle
There are two massive, ruined, unmarked ARCs in this region: one west of the Adorned Wreckage and another east of the Maintenance Bunker. You will need 2 ARC Powercells, as you need them to activate the loot spots.
For reference, this guide uses the Deforester found nearest to the Maintenance Bunker.
- Go inside the large turbine on the southeast side. Interact with the broken fuse box inside to fix it by expending an ARC Powercell. Beware, as this will cause fire traps to activate.
- Go past the fire trap in the turbine and fix the next fuse box at the end of the turbine.
- Climb up the platform leading to the top half of the turbine. Jump inside and interact with the node at the end to disable the traps and loot some valuable components.
Reinforced Reception Puzzles
The Reinforced Reception area has multiple puzzles that can get you a big haul if you complete all of them. Of course, you will need a teammate to cover, as you’ll need to carry a battery that requires both hands.
Terminal Color Loot Room Puzzle
- Head to the building and rappel down the elevator shaft. This will lead you to a hallway.
- Turn left and interact with the terminal. Activating it will display a color on its screen: red, blue, or yellow. Whatever color it shows, follow the colored line and markers on the floor and walls, as it will lead you to a loot locker.
- Be aware that approaching the loot locker will trigger an alarm, alerting other raiders to your position.
Battery Gate Loot Room Puzzle
The spawn locations for the three batteries in Reinforced Reception are semi-randomized, but here are the possible spawn locations:
- Underneath the stairs, next to the red and blue L and R symbols
- In the first room on the left, while following the blue line
- Above the stairs, next to the doorway, and a few benches
You must carry all 3 batteries through the blue line path until you see a shutter gate on the right side with three battery slots beside it. Once all 3 batteries are slotted in, there is a chest at the end of the room with loot.
