March 9, 2026: With the new map now available in-game, we've added the Outpost DCON locations below.

Marathon isn't exactly fluent at explaining its many systems and mechanics. One such hurdle you'll soon run into when completing some early quests is DCONs, which you'll need to find and interact with before being formally introduced to them—often while racing the clock. Knowing the DCON locations ahead of time can save you a lot of hassle.

Marathon DCON locations

DCON are terminals with antennae, located either outside or on the roof of specific buildings across the maps, where you can deposit items for certain contracts. Whenever you require a DCON during a quest, they should be marked on your map with a unique crate icon, but this is bugged for some players.

Here are the DCON locations on each map:

Perimeter

  • North Relay: On the roof of the shelter just northwest of the North Relay, in the corner of the map
  • Station: Northeast of Station, past the pipe near the northern walkway and the cliff
  • Overflow: Directly west of Overflow near the cliffs, not far from the main building
  • South Relay: In the hills in the far south of the map, past South Relay and Columns. This one is much further away from the main POI than the others

Dire Marsh

  • Complex: Outside the building in the marsh, south of Complex, east of AI Uplink
  • Greenhouse: On the south side of the building in the hills just north of Greenhouse
  • Quarantine: Outside the building in the marsh directly south of Quarantine

Outpost

  • Airfield: Inside the western hangar on the ground floor, near the hole in the ceiling
  • Processing: In the dock south of the main building, near the large shipping containers
  • Orientation: On the ground level in the northeast corner of the map, between Orientation and Dormitories

Head to any of these DCON locations and interact with them to open the terminal's inventory. For any contracts that involve using these machines, you'll be able to transfer the quest items into the terminal's inventory, which will then be deposited and sent off into space when you close the menu.

Unfortunately, these DCON terminals can't be used to safely send items back to your vault mid-match, like a suped-up safe pocket, though it would be pretty cool if they could.

Rory has made the fatal error of playing way too many live service games at once, and somehow still finding time for everything in between. Sure, he’s an expert at Destiny 2, Call of Duty, and more, but at what cost? He’s even sunk 1,000 hours into The Elder Scrolls Online over the years. At least he put all those hours spent grinding challenges to good use over the years as a freelancer and guides editor. In his spare time, he’s also an avid video creator, often breaking down the environmental design of his favourite games. If you can’t track him down, he’s probably lost in a cave with a bunch of dwarves shouting “rock and stone” to no end.
