The Arc Raiders A Dead End quest is one of the tougher missions out there, based around an existing Battery Puzzle in the Mantikor Facilities' Security Wing. Players have to find the locations of 3 Batteries to open the locked Capacitor Door and access the Red Room beyond it, but what's worth knowing is that this is a puzzle that can be completed even when you're not doing the mission, earning you major rewards and a chance for valuable loot. If you want to know more about to how to access these things and complete the quest A Dead End in Arc Raiders, our guide will lay out all th key steps and locations to make it easier.

Where to find Mantikor's Underground Facilities in Arc Raiders

When you first get to Blue Gate, the first objective is to find Mantikor's Underground Facilities. There's actually several ways to access these, as it's the area behind the Blue Gate itself. For this mission though, we recommend you go down via the zipline at the unmarked building above, for reasons that will be explained momentarily. This will take you down to the Security Wing, where the rest of this quest takes place.

How to get into the Locked Door in the Security Wing

Assuming you took the entrance marked above, you'll follow a path into an open reception with a huge locked gate on the left, one that can't be opened because it's depowered. This is the Security Wing locked door mentioned, and what you need to do is get inside. To do so, you'll need to complete the Battery and Capacitor puzzle, outlined below..

Capacitor Door puzzle and Battery locations

To solve the battery puzzle and open the capacitor door in the Security Wing, you need to find three Capacitor Batteries around the Security Wing and insert them into the panel on the right side of the door. These Capacitor Batteries are held in both hands, rather than in your inventory, so it'll be slow going while you have one and you'll be defenceless. Be ready to drop it if you need to fight.

The batteries are in various locations and to some extent are randomly found around the Security Wing. Here are three potential locations that the Batteries can spawn in:

The official battery dispenser. This is shown above, in the central staircase room, next to yellow graffiti.
Under the stairs by the ziplines to the reinforced reception at ground level. It's marked by some red graffiti on the wall.
In the central computer room. The computer banks in the middle of that room sometimes house a battery.

Bring all three back to the panel and insert them to power up the door, which you can now open to access a Red Room beyond.

Where to search for Records in Arc Raiders

Once inside the locked red room, you need to simply interact with the computer at the back of the room to play the recording, on the right of the main screens, then interact with the film bank on the left to get the Dusty Film Reel. Once you have it, simply extract safely with that Film Reel and give it back to Shani in Speranza.

Arc Raiders A Dead End rewards

For completing the quest A Dead End, you'll get 2000 coins and a new variant of the Warden Skin. It'll also unlock a follow-up quest called "A Rising Tide".

Of course, it's worth keeping in mind that the Battery Door and Red Room can be opened even when you're not doing this quest, and that it's a high loot area beyond. Crack it open whenever you get the chance! If you're playing missions added in the Arc Raiders Shrouded Sky update, you should be high enough level to really make use of the good loot.
