Outpost Infra-Station Mission Guide

To start the mission, press V to check your Messages. You will receive a concerning message from Da Pan, who says that Noffman and his SAR crew members have not returned yet to the camp site.

Open your Maps, and select the TP Point between Originium Science Park and the Research Center. The marker is just south of the Research Center, which will lead you to Noffman.

Upon arriving at the building, you will come across a few Landbreakers along the way. Engage in battle and defeat them all to continue. When you've defeated them, the team will interrogate a dying Landbreaker about the UWST Equipment.

Find Noffman by following the marker, before approaching him and his injured team. There, they talk about heading back to the camp at once to avoid further peril.

After Da Pan mentions that the Endfield team has Ziplines, you must now make the unit to cross over the chasm. Zipline Towers can be used to travel across the map with ease and can be unlocked via the AIC Plan System.
| How to Build Zipline | |
|---|---|
| 1 | ![]() Move towards the marker, where you will see the cliff and the chasm below. This is where you'll place the Zipline Tower. |
| 2 | ![]() Open your backpack and choose the Zipline Tower. |
| 3 | ![]() After selecting the Zipline Tower, place the facility in the specified area and click to confirm its position. This will establish your starting point to your destination. |
| 4 | ![]() Go to your inventory again and select the Electric Pylon and place it next to the Zipline Tower. Doing this will infuse the Zipline with a power source. |
| 5 | ![]() Move towards the Relay Tower and start its transmission. This will give you a tether, which you will now attach to the Electric Pylon. |
| 6 | ![]() Attach the tether to the Electric Pylon. This will automatically power the Zipline for functional use. |
| 7 | ![]() After you're done on the cliffside, open your Maps and select the AIC Facility at the Infra-Station. There, you will find the marker, which you will place your second Zipline Tower on. |
| 8 | ![]() Repeat the process by placing a Zipline Tower and an Electric Pylon beside each other. |
| 9 | ![]() If you are short on distance, place another Electric Pylon nearby, just enough to close the gap. With the same process in mind, these Pylons need a power source. |
| 10 | ![]() Attach the Pylon's tether to another Pylon within the proximity of the AIC Facility. Doing this will automatically power your second Zipline Tower. |

When you're done fixing the second Zipline, approach it and press the Latch to Zipline Facility button, which will carry you over to the other side of the terrain.
Arriving there will trigger a conversation that will indicate the recovery of the injured crew members, thus completing the mission and increasing the level of the Infra-Station.
