Stuck staring at sand, half-buried rail cars, and a map marker that tells you almost nothing? The Line in the Sand quest can feel oddly picky, especially if you burn supplies, lose the business card, then wonder whether spending on ARC Raiders Coins would have been less painful than another messy Buried City run. I get it. This mission is simple on paper, but the game hides the useful clues in places players naturally walk past.

Line in the Sand quest route and key locations

Start at the derailed train, not Marano Station

The first trap is the name. Marano Station sounds like the obvious target, but the wreck you need sits south of it, in the central Buried City area between the Warehouse and Maintenance Depot. Look for the train swallowed by sand. You do not need to loot anything here; getting close enough should trigger the objective update.

Personally, I would approach from the west if the lobby feels hot. The open ground around the wreck can turn ugly fast, and Version 1.7 made some patrol routes feel less forgiving. Bring a light kit if you are only doing quest progress. No heroics needed.

Find the business card at the stone tower

After the derailment updates, head northeast toward the small stone tower at the end of a wall west of Piazza Roma. Inside, interact with the prompt to pick up the Marano Market Business Card. Now pause for two seconds. Put it in your Safe Pocket.

That last bit matters more than most guides admit. If you die with the card loose in your inventory, you are making the tower trip again. Annoying. From what I have seen, this is the mistake that turns a 10-minute errand into a full evening of grumbling.

Line in the Sand quest objectives after the card

Go to Market Ruins for the thruster valve clue

The business card points you toward Marano Market, but the map label you want is Market Ruins. It sits northeast of the Hospital. Move near the outside of the building, close to the north-side raider hatch, and the objective should update without much ceremony.

Here is the clean route I use when I am not trying to farm every container in sight.

1) Trigger the derailed train objective south of Marano Station.

2) Move northeast to the stone tower and grab the business card.

3) Safe Pocket the card before leaving the room.

4) Cut toward Market Ruins, staying off the widest roads when enemy density is high.

5) Wait for the objective update near the building exterior before pushing onward.

Photograph the basement boxes at the merchant apartment

The final stop is the one players miss because it lacks a friendly, obvious marker. From Market Ruins, head northeast toward the map edge, just north of Dune's End. You are looking for an eastern building with access down by zipline or elevator. The basement contains a pile of boxes tied to the stolen hardware.

Do not just stare at the boxes. Use the camera tool and take the photo. Honestly, this feels a bit old-school in a fussy way, but the manual photo is what completes the objective. After that, extract and return to Celeste in Speranza for 2 Exodus Modules, 2 Magnetic Accelerators, and 2 Magnetrons.

Line in the Sand quest mistakes, rewards, and smart prep

What to carry and what to skip

For the Line in the Sand quest, I prefer mobility over firepower. A bulky loadout tempts you into side fights, and side fights are how quest items vanish. If you are also collecting for projects like Avian Alarm, grab rare materials when they are directly on your path, but do not turn this mission into a shopping trip unless the server feels quiet.

• Safe Pocket space for the Marano Market Business Card
• Camera tool ready before entering the basement
• Enough stamina items for a long northeast route
• One reliable weapon, not your most expensive kit

Myths that waste time

One myth is that the business card still matters after the photo. It does not appear to have a quest use once the final objective is done, so selling it afterward is fine. Another myth: the merchant apartment is inside Market Ruins. Close, but no. Keep moving northeast toward Dune's End.

There is also some debate around unlock prerequisites. The quest commonly follows A Wrench in the Works, but exact requirements are still muddy. If Celeste has not offered it, finish nearby Buried City tasks first rather than chasing random Riven Tides objectives.

Run it clean: train, tower, Market Ruins, basement photo, extract. If you want to reduce the sting of failed attempts, plan your supplies before queueing and consider whether to buy ARC Raiders Coins for account flexibility while you focus on the route itself. The quest is not hard once the map stops lying to you.
