Contracts in Bungie's new extraction shooter Marathon will ask you to visit different spots on each of its maps, though a common theme is asking players to deposit specific items into devices called DCONs, which transport matter imbedded into them off planet.
Its a way of getting the salvage or resources you're being sent to Tau Ceit IV's zones to retrieve to the factions asking for them, and thankfully, each zone (Perimeter, Dire Marsh, and Outpost) has at least three that you can head towards once you've acquired the necessary salvage.
This guide will show you where all of the DCONs in each zone are located, so you'll know where to go, since they don't immediately appear on your map if you haven't found them yet. However, once you have found them, they will appear on your map, so long as you have a contract that requires you to head to DCONs activated.

All DCON Locations in Marathon - Guide
Perimeter
There are four DCONs on Perimeter, which you can see in the map above. All DCONs in Perimeter are on the roof of buildings, though that rule only applies to DCONs found here.
- There's one just west of the North Relay, towards the top left corner of the map
- Another just north of Station, towards the top right corner of the map
- On the opposite end from the North Relay DCON is one just west of Overflow
- The most remote DCON is far south of South Relay and Columns
Dire Marsh
Dire Marsh houses three DCONs, which you can see on the map above. DCONs in Dire Marsh are on the ground, in front of the buildings where they can be found.
- One is south of Complex and east of AI Uplink, towards the bottom right corner of the map
- There's a DCON north west of Greenhouse, towards the top of the map
- Another is located south of Quarantine, on the far west region of the map
Outpost
There are three DCONs on Outpost, each in one of the three major regions the map is split between.
- One is in Processing, in a dock just south of the main building in the bottom left corner of the map
- Another is in the northeast corner of the map, in between Orientation and Dormitories
- The other is inside the western hangar of Airfield with a hole in the ceiling above it
