How to Deliver Unstable Gunmetal to DCON in Perimeter (Marathon)

How to Deliver Unstable Gunmetal to DCON in Perimeter (Marathon)

The rain on the Perimeter roof hissed under my boots while I counted scraps in my pack. A DCON blinked two blocks over, stubborn as a ledger; I had seven unstable pieces left to find. I made a plan that took five short runs and one stupid mistake to perfect.

I’m the kind of player who hates backtracking, so I’ll tell you the fastest way I clear this contract: what to grab, where to go, and the exact moment you should climb the ladder and close the loop. You won’t need a pocketful of theories—just a few practical habits and a little route memory.

Quick summary: You need seven Unstable Gunmetal. They spawn in containers across Perimeter; the DCON you deliver to sits on a Station POI roof to the east. Collect, climb, deposit, and reap Traxus rep.

Observation: You’ll often find the same container types giving the same scraps on repeat runs.

How to find Unstable Gunmetal in Marathon

I started treating runs like a shopping route: containers first, combat loot second. Unstable Gunmetal is a random drop, but it favors boxes, lockers, and small supply crates across Perimeter. I collected them casually while completing other objectives and kept a running count in my head—seven is the target.

Practical routine that saved me time:

  • Hit high-traffic POIs early (Station, alleys, roof entrances) and open every container you pass.
  • Pause when you’re at five pieces—some runs yield duplicates from the same types of containers, so note repeat spawns.
  • If you’re using overlays or community tools (Destiny item trackers and map pins, or Moyens I/O’s route screenshots), mark spots that produced multiples on a previous run.

Unstable Gunmetal is a loose currency of the map. The DCON is a locked ledger of favors.

Where can I find Unstable Gunmetal in Marathon?

People ask this because they expect a fixed node. There isn’t one. You’ll find them in random loot containers while clearing the Perimeter. Prioritize containers near the Station POI and the rooftop corridors; they consistently yield higher container density per minute than empty streets.

Tip: If you’re running with friends, split container sweeps—one covers rooftops, one hits alleys—then meet at the Station roof. That halves the time per person.

Observation: The DCON isn’t buried in a cave; it’s visible from the east approach of Station.

Approach the Station POI from the east and scan rooftops. The DCON sits on a rooftop structure and looks like a small supply box. Your endgame is simple: climb the ladder, open the DCON inventory, deposit seven Unstable Gunmetal, then interact again to finalize the transfer.

Step-by-step:

  1. Run east from Station POI toward the marked roof area in the image above.
  2. Take the ladder up—don’t rush past the platform; the ladder is the intended approach and avoids extra firefights.
  3. Open the DCON’s inventory UI and add exactly seven Unstable Gunmetal from your backpack.
  4. Interact a second time to complete the task. You’ll receive Traxus rep and progress on the Equitable Distribution 3/4 contract.

How do I deliver Unstable Gunmetal to DCON on Perimeter?

Delivering is procedural: reach the DCON, open it, deposit seven stacks, and interact again. If it doesn’t accept items, double-check that each piece is the Unstable Gunmetal item and that you have exactly seven in your inventory.

Practical checks: if you’re short, redo a fast container sweep—set a personal timer for five minutes and sprint the high-density route. If you’re playing on PC, community mapping tools and icons from Moyens I/O readers can speed up repeat runs.

Observation: Completing this transfer moves Traxus rep; reputation happens one deposit at a time.

Why this matters: the rep moves you toward better rewards and upgrades for your builds. Think of that progression as a small economic cycle inside Destiny—fewer runs, clearer returns.

If you want a final habit, keep a mental tally of where you picked up Unstable Gunmetal on each run and reuse that route three times; odds favor repetition. Do you treat Perimeter runs as looting sprints or careful patrols?
