How to Complete the Line in the Sand Quest in ARC Raiders

Line in the Sand is a new quest in ARC Raiders introduced with the Riven Tides update. Unlike other quests in this update, it does not take place on the new map. Instead, players must travel to Buried City to complete a series of tasks.

Line in the Sand Quest Walkthrough

The quest is divided into five key objectives:

  • Find out why the train never reached Marano Station
  • Find out who orchestrated the robbery
  • Collect the Marano Market Business Card
  • Find out where the thruster valves were stashed
  • Search the basement of the merchant's nearby apartment

1. Find Out Why the Train Never Reached Marano Station

Your first task begins at the broken-down train located in the western part of the Buried City map. Approach the train to receive a prompt that provides details about its failure to reach Marano Station.

2. Find Out Who Orchestrated the Robbery

From the abandoned railcar, head slightly east to locate a small tower. Climb the metal walls to reach a terminal on the floor. Interact with the terminal to uncover clues about the robbery’s mastermind. Once completed, proceed to the next objective.

3. Collect the Marano Market Business Card

After retrieving information from the terminal, you will obtain the Marano Market Business Card. Store this item in a safe pocket immediately, as you will need it later in the quest.

4. Find Out Where the Thruster Valves Were Stashed

Follow the map marker to the Market Ruins. Upon arrival, the quest will update with new information about the thruster valves’ location, even if the valves are not immediately visible.

5. Search the Basement of the Merchant’s Nearby Apartment

Travel to the northern part of the map and enter the building marked on your map. Inside, locate a zipline and use it to descend to the basement. Search the basement to find a set of boxes. Interact with the prompt to complete the final task and finish the Line in the Sand quest in ARC Raiders.
