What to Do Next in ARC Raiders After the Robbery Clue — U4N Guide

The “Line in the Sand” quest in ARC Raiders includes an investigation step that can be surprisingly easy to miss. After examining the derailed train, you need to search for a nearby clue that reveals more about the robbery. Players collecting ARC Raiders Items along the way should take a moment to secure the quest objective before leaving the area, as the hidden location is not immediately obvious.

The next part of the investigation takes you toward the city, where a small lookout tower is partially surrounded by sand. Rather than searching randomly, follow a straightforward route from the train wreck and focus on the area around Piazza Roma. Knowing the correct landmark and where to look inside it can make this section considerably quicker.

Leave the Train and Head East

Once the first step at the derailed train is complete, turn your attention toward the city. Travel east or northeast from the crash site, keeping the Piazza Roma marker in mind as a navigation reference.

The lookout tower is positioned northwest of Piazza Roma. It is a relatively small structure that rises above the sandy terrain, so its appearance can be easy to overlook while moving between larger landmarks.

Avoid going too far into the city. The objective is located much closer to the train than it may initially seem. If you find yourself surrounded by dense urban areas, you have probably traveled farther than necessary.

Identify the Sandy Lookout Tower

As you approach the correct area, watch for a small tower protruding from the sand. This structure serves as the main landmark for the investigation objective.

Once you locate it, move around the structure rather than immediately continuing toward the next map marker. The clue is associated with the rear portion of the tower, so positioning yourself correctly is important.

The surrounding terrain can also affect visibility. Sand, bushes, and miscellaneous objects may partially obscure the area where the interactable appears.

Search Behind the Structure

Your next task is to reach the back of the tower. Depending on your position and the terrain, you can mantle or climb into the rear section.

After getting inside, inspect the corners carefully. The hidden stash is not placed in a prominent central position. Instead, it can blend into the environment, particularly when nearby objects block your view.

Check around bushes and other pieces of debris. A plunger box may also be close to the clue, providing a useful visual reference when searching the area. If nothing appears at first, reposition yourself and examine the corners from another angle.

Collect the Business Card

The object you are looking for is an interactable stash containing the Marano Market Business Card. In some situations, it may instead be presented as a market blueprint.

Interact with the object and collect the card once it becomes available. Picking it up is what advances this section of “Line in the Sand,” so there is no need to keep searching the tower after securing the clue.

The card is an important quest item, making it worth taking an extra moment to confirm that it has entered your inventory before moving away from the structure.

Protect Your Quest Progress

After collecting the card, place it into your safe pocket. This is especially useful if you still need to travel through dangerous areas before completing your current expedition.

Losing the item after being eliminated can make the process more frustrating because you may need to return to the same hidden location. Securing quest-related objects immediately is therefore a practical habit when exploring the map.

Follow the Updated Objective

The moment you pick up the Marano Market Business Card, the investigation progresses to the next objective: “Find out where the thruster valves were stashed.”

You do not need to return to the derailed train or continue examining the lookout tower. Once the new objective appears, review the quest information and begin preparing for the next stage.

Finish the Investigation Step

The route for this section is simple once the key landmarks are understood: leave the derailed train, travel east or northeast, find the lookout tower northwest of Piazza Roma, climb into its rear section, and inspect the corners for the hidden stash. Collect the Marano Market Business Card and secure it before continuing. Keeping cheap ARC Coins available can also provide additional flexibility when preparing for future activities and trading needs.
