ARC Raiders' "Line in the Sand" quest is one of those missions that feels simple on the surface, but ends up playing like a small investigation once you're actually in Buried City. Celeste basically sends you to figure out what happened to a train that never made it to Marano Station, and from there it turns into a chain of clues that connect a crash, a robbery, and a hidden trail of supplies. Most recent walkthroughs from sites like IGN, Polygon, GameSpot, and GameRant all more or less agree on the same route, and the good news is you can finish it in one run if you don't rush too much or lose track of the steps ARC Raiders Coins.
It all starts on the west side of Buried City near Marano Station, which sits close to places like the Library and Piazza Roma. When you get to the train wreck, don't just circle it randomly. The game only moves the quest forward when you approach the southern side near the trees, which is where it registers the crash properly. It's a small detail, but a lot of players miss the trigger just because they don't stand in the right spot.
Once that's done, the quest shifts from "what happened here" to "who was involved." You'll head east toward Piazza Roma, where you'll find a small tower structure in the middle of the area. Climb inside and you'll be able to pick up the Marano Market Business Card. This is one of those items you really don't want to drop or lose, so most guides recommend putting it straight into your Safe Pocket as soon as you get it, just to avoid unnecessary backtracking later.
From there, the trail continues further east, past the Hospital area, into the Market Ruins. This part is pretty straightforward compared to the earlier steps. You basically just need to reach the marked location and the objective updates on its own, hinting that the train incident wasn't random at all. Instead, it feels tied to some kind of organized supply or black-market route running through the city.
The final stop is in the northeast, at a merchant apartment. Inside, you'll need to find your way down to the basement using the elevator at the back of the building and then continue down with a zipline or stairs. Down there, you'll inspect a stack of crates to finish the investigation. A few players have reported minor bugs if they abandon the run mid-way, so it's usually safer to extract normally once you've started collecting quest progress.
What makes this quest stand out is that it doesn't really feel like a typical "go here, grab item, leave" mission. The broken train, the hidden card, the market connection, and the basement stash all line up into something that feels more like uncovering a smuggling route than just completing objectives. It also helps that the path is pretty logical once you see it: west for the crash, center for the clue, east for the ruins, then northeast to wrap it up.
If you want to finish it cleanly, the best approach is just to treat it like a slow loop through the city instead of a fight-heavy run ARC Raiders Coins On PC. Go in with space in your safe pocket, keep an eye on each trigger point, and don't worry too much about combat unless you have to. It's more about paying attention to where you are than forcing your way through enemies.
