Before you deploy, one crucial tip: bring an augment with ARC Raiders Coins a safe pocket. You'll need to extract with a quest ARC Raiders Items at the end, and storing it safely ensures you can still complete the mission even if you're eliminated before reaching an extraction point.

Let's break everything down step by step.

Find MANTIKOR's Underground Facilities

Your first objective is to locate MANTIKOR's underground facilities, which are situated in the middle of the Blue Gate map inside the Security Wing.

There are multiple entry points to the underground area:

Checkpoint gates

Headhouse access

A small structure with a zipline (fastest route)

The zipline entrance at the small marked structure is the quickest and most efficient way down. It drops you directly into the underground network and minimizes time spent exposed above ground.

Once inside, navigate toward the Security Wing. Compared to other points of interest, it's relatively compact, so you shouldn't get too disoriented.

Open the Locked Room in the Security Wing

Inside the Security Wing, you'll find a large locked door with a battery console mounted to the right side. To open it, you must locate and insert three batteries scattered around the Security Wing.

Here's what you need to know:

Battery spawn locations are random.

The Security Wing is small, so search thoroughly.

Batteries are typically placed on surfaces, near machinery, or tucked into corners.

Because this is a shared objective, other raiders may already be working on it. In fact, you might arrive to find:

One or two batteries are already inserted

The door is fully unlocked

If you're running solo, move cautiously while searching. If you're in a squad, split up and sweep different sections to speed up the process.

Sometimes cooperation-even temporary alliances with random players-can help everyone get the door open faster. Once all three batteries are inserted, the locked room will unlock.

Search for Records of Project Heartwood

After the door opens, head inside and move toward the back of the room, where you'll see a large screen dominating the wall.

On the right side of the screen, there's a machine with ARC Raiders Items an interaction prompt labeled "Play Recording."
