How to Scan FTL Array at USEC Radio Tower (Marathon Guide)

I was three steps up the ladder when the yellow quest marker blinked out. Two teammates were patching wounds and the timer felt personal. You either scan the FTL Array now or leave the contract on the table.

First, accept and keep the contract active. Right now the game limits you to one active contract at a time, so if you want the rewards you must carry this one through the run.

I favor running these with at least one teammate; coordination smooths out the brief chaos when you reach the tower. Start the run on the Perimeter map — that’s where the contract points you — and head toward the Station POI. The Station is the easiest landmark to find; treat it as your staging area.

Where is the FTL Array on the Perimeter map?

Use the overhead compass: the tower sits roughly at E 100 from the Station area. The quest icon will appear as a yellow marker when you’re in effective range, but if you want a shortcut, head east from the Station until the tower silhouette reads like a stubby lighthouse against the skyline.

The radio tower requires a quick climb before you can touch the terminal. How to scan the FTL Array in Marathon

When you arrive at the tower, take one of the ladders up. There’s a blue terminal near the top that holds the FTL Comms Chip — it’s interactable and will trigger the scan.

How do I scan the FTL Array at a USEC Radio Tower?

Climb, approach the blue terminal, and interact with the FTL Comms Chip. The interaction completes the scan and marks the contract objective as finished. If the icon is on your HUD, following it is a safe bet; if not, move to coordinates near E 100 from the Station and check the tower.

Can I complete this contract solo or with teammates?

You can finish it solo, but I recommend a partner. Teammates make the run quieter and reduce the chance you’ll be wiped before the scan completes. If you’re tentative, check community threads on Reddit or quick clips on YouTube — creators often show the exact route and angle to shave time.

After the scan completes, end the run and collect your rewards. The contract behaves like any other: complete the objective during the session, extract or end, then accept the payout in the contract menu.

I used the compass, the Station POI, and a quick climb to finish this in under a minute once I knew the route — it’s a short task that rewards attention more than firepower. Want to argue whether teamplay or speedruns make this more fun?
