The quest to find earthquake-resistant housing details in Arc Raiders remains unresolved, as it appears the project was abruptly shut down without explanation, despite its significance and usefulness. This situation is confusing and frustrating.
Shani and the other key members of Speranza are determined to uncover what happened to the project. The townspeople need this knowledge to build safer underground homes, since the surface remains too dangerous for the last survivors. Your next clue takes you to the Blue Gate, where you’ll investigate MANTIKOR’s involvement in the project’s cancellation.
### Where To Find The MANTIKOR Facilities
To continue Shani’s investigation, go to the Blue Gate. Every step in this quest must be completed in one run; otherwise, it won’t count. You need to visit the underground facilities marked with the orange MANTIKOR logo. There are two ways to reach the Security Wing where the mission objective is: First, enter through the Outer Gates at the Checkpoint POI and go up the stairs; second, go to the Reinforced Reception located at the north end of the map and descend via ziplines and stairs.
Getting close to the MANTIKOR facilities will trigger the quest objective. Keep in mind, the room you need to access differs from the Blue Gate Confiscation Room. Instead, it resembles the fuel-cell doors found in Stella Montis. To find it, head to the center of the Security Wing, where two ziplines lead up to Reinforced Reception, and look for the blue line painted on the floor.
> There’s a room in the Security Wing that stays locked with a Door Blocker unless looted. Inside, you’ll find valuable items like a weapons crate, metal lockers, and possibly two security breach lockers, without requiring a key.
Follow the painted line past several rooms, clearing out fireballs and pop rollers that approach from the long, broken-down hallway lined with arches and remnants of robots. Stop in a small, open space featuring a large shuttered door with an attached electrical box and a desk with multiple computers.
This shutdown door is what the quest specifies. The remaining objectives are inside, but the door won’t open until you solve a puzzle in the surrounding area.
### How To Get Into The Locked Room
To open the door, find three white, medium-sized batteries hidden at specific spots around the room—these are placed on battery holders. Collect them and carry each one back to the electrical box on the wall, then insert them to unlock the door.
> Some players report issues with the batteries spawning or the electrical components not responding, even in confirmed locations. However, another player can open the door for you, and you can still access the rest of the quest without problems.
There are a few known spawn points for the batteries:
– One may appear in an alcove near the stairs leading down to the lowest underground floor, next to a wall marked with yellow graffiti and arrows pointing to machinery.
– Another might be beneath the staircase that leads to the ziplines, on the wall with red graffiti indicating direction.
Batteries are carried like fuel cells, so you’ll need to make multiple trips unless a teammate assists. Once all three are placed, the door opens, allowing you to proceed.
> If the electrical box by the door isn’t highlighted in blue, the step might be bugged. This indicates a glitch, but another player can open the door for you, allowing you to complete your objective.
### Where To Get The Dusty Film Reel
Inside the room, you’ll find various loot, but the next step involves the tape player located in the corner downstairs. Interact with it to play the tape and advance the quest.
Next, move to the left side of the monitor wall, where you’ll find a film reel container that looks like a washing machine. Completing this puzzle is optional — you can do it any time you visit The Blue Gate while looting the area, which includes crates, drawers, and a weapons crate.
Once you do this, you’ll receive the Dusty Film Reel, the item needed for the final step. Return to Speranza, speak with Shani, and complete the quest. As rewards, you’ll earn experience points, unlock the Warden color for the Patchwork Outfit, and gain 2,000 credits, in addition to the loot from the locked room.
