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.
Reference: Bungie’s item system and the Traxus faction reputation matter here; the images below are from my runs and the studio’s renders via Bungie and Moyens I/O.

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.
How to deliver Unstable Gunmetal in Marathon
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:
- Run east from Station POI toward the marked roof area in the image above.
- Take the ladder up—don’t rush past the platform; the ladder is the intended approach and avoids extra firefights.
- Open the DCON’s inventory UI and add exactly seven Unstable Gunmetal from your backpack.
- 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?
