Outpost Infra-Station Mission Guide

To start the mission, press V to open your Messages. There, you will see the Temporary Infra-Station Comms asking for the location of Noffman. Landbreakers have attacked a refuge point, prompting the Endfield team to check the situation.

Open your Maps, and select the AIC Facility near top left the Infra-Station. The marker is in the centerpoint of the yellow radius, which will guide you to two crewmates.

When you have arrived at the Infra-Station, head towards the crewmates. The team asks them the location of Noffman, and they'll reveal that Noffman will be installing hardware on the tower. Completing the conversation will finish 1/3 of the tasks for you.
| How to Find Engineering Work Notes | |
|---|---|
| 1 | ![]() The notes can be found inside a container van. A note can be found sitting on top of the table near the vents. Approach and collect the item. |
| 2 | ![]() Another note can be found across the room, which, if collected, will finish all three tasks in your objective. |

Talk to Da Pan, who will inform you that he needs more manpower to setup the hardware and mount a signal receiver on the watch tower. He will also mention that Noffman is at the Control Center.

Have your Maps ready and use the TP Point in Route 5. The marker will require you to go north, leading you to the Control Center. Go inside the building to help Noffman.

The next objective would fixing the two thermostats inside the Control Center. You will need to stabilize the temprature in the units by hitting them with consecutive attacks.
In the first thermostat, place hits that will keep the bars in sync with the green highlight. Make sure to land your attacks, or else you won't be able to maintain the bar level's tuning.

Same as the first thermostat, the second one will also need to be hit with continuous attacks. Keep the momentum by making each hit count.

After tuning the two thermostats, head down to talk to Noffman. This will trigger a conversation where Da Pan and Endmin accompany Noffman back to the Infra-Station.

Return to the Infra-Station and talk to Noffman. Finishing the conversation will automatically conclude the mission, as well as inform you that the level of Infra-Station has been increased.
