If you want to increase the quality of your equipment during a raid in Arc Raidersthen you'll eventually want to make your way to The Blue Gate map. The toughest map currently available, this endgame-like map offers not only a plethora of challenging ARC enemies and terrain, but several small puzzles that reward you upon completion.
One of these is located at the ancient fort and requires the player to find three hidden batteries to power up a locked cellar door. While this sounds easy on paper, finding the batteries can be a bit of a headache if you don't know where to look. Here's what you need to know so you can quickly complete this puzzle and grab some serious loot!
Where to find the old fort puzzle
You can find the ancient fort puzzle at, duh, the interesting site of the ancient fort on the blue gate. In the southeast part of the map, players will have to make their way down here and find a large stone structure. On the east side of the fort you will find a cellar door which is currently locked and has three cables leaving it. This is where all the loot is locked, so be sure to keep this location in mind as you run around.
Thankfully, the Ancient Fort is pretty out of the way, so there's a decent chance you might not run into a lot of ARC enemies outside of wasps, hornets, and snickers. Also, the town just northwest of the fort will either spawn a Leaper or a Bombadeer, so try to keep your distance from them!
How to complete the ancient fort puzzle
To unlock the basement, you need to find three batteries and carry them to the three different electrical boxes. These batteries are roughly the same size as the field boxes you've almost certainly already encountered and cannot be stored in your inventory. Carrying a battery will drastically slow your movement, stow your weapons, and drain your stamina quickly if you try to run with it.
You will need to bring three different batteries for each of the electrical boxes. These are available:
- Directly along the southernmost wall of the fort.
- On the second floor of the tower inside the fort.
- On the second floor of the fort on the north side.
The location of these electrical boxes never changesand you can tell when you're getting close to one because it will glow bright blue if you're near it with a battery. They will also open at an angle, making them quite easy to spot.
Remember, if you ever have trouble finding one, just follow the wires coming from the basement.
All Ancient Fort Battery locations
When it comes to actually finding the batteries, they will be located both in and around the fort. The main way to see where a battery can play is that there will be a very clear wooden pallet on the ground that the battery will play on top of. Now the pallets will stay there regardless of whether a battery has been created there or not, but it's a good visual cue to look for when you're looking for them.
In my tests I have discovered twelve potential spawn locations for the batteries. There may be more, but I have yet to encounter this puzzle where I couldn't find all the batteries in the indicated locations. Remember that it only comes with three batteries, so be careful to check every single place.

Once you gain access to the basement, just head down the stairs into the basement and enjoy your loot. Along with a gun case, you'll find several electrical and medical themed items. Advanced electrical components will also spawn on top of the computers, so be sure to check them before you leave! Remember that the basement only has one entrance, so make sure no raiders are waiting to hear you before you start looting.
