The Line in the Sand quest in Arc Raiders is a simple investigation mission set in the Buried City. In this quest, you’ll follow a group of clues to find out what happened to a missing train and who was behind the incident. It doesn’t require any special gear or preparation, so you can jump in with whatever you have. Most of the objectives are easy to complete just by reaching the right locations. In this guide, we will tell you how to complete the Line in the Sand quest in ARC Raiders.
Line in The Sand Quest


Start by walking towards the Buried City. Head towards the far western part of the map. You need to find a small group of trees, close to a warehouse and railway tracks. Simply head towards the bushes at this location. From there, move towards a little to the east side where you can see a small tower structure. Just approach its rear side and enter inside it.
Once inside, you need to find something close to a bush that you can interact with. Once you use it, you will get an item, which you must collect. After that, go to the ruins of the marketplace. All you need to do after reaching here is simply approach some buildings located here.
Search the Merchant’s Apartment Basement


For the final step, go northeast along the nearby path until you reach a merchant’s apartment building. Enter the building, find the elevator, and head downstairs to the basement. From there, all you need to do is look to your right, where you will find a stack of boxes. Interact with it to take the photo, and thus complete the final objective. After returning to Celeste at Speranza, you can complete the mission and get your reward items. You’ll receive two Exodus Modules, two Magnetic Accelerators, and two Magnetrons for completing it.
