What to know
-
This objective appears as Step 9 in the “Building an Outpost” quest flow, after you craft Gun Towers via the Facility List.
-
The game often won’t accept “close enough”; you need to snap/place towers directly on the marked spots.
-
If towers place but don’t work in combat, the next step is powering them with an Electric Pylon and transmitting power from the Sub-PAC.
-
This whole quest is a tutorial for outpost automation: Sub-PAC placement, belt routing between ports, and then defense + power.
You’re basically being tested on two things: whether you created Gun Towers as placeable items, and whether you placed them exactly where the quest wants them. Once you do, the quest moves on to powering the towers and surviving the next Landbreaker attack.
Quick flow context
| Quest segment | What you do right before towers | Why it matters |
|---|---|---|
| Outpost core | Place the Sub-PAC | Establishes the local hub/power source used later. |
| Logistics loop | Connect Sub-PAC ↔ Refining Unit with belts (correct ports) | The quest validates ports and completed routing, not just visuals. |
| Automation check | Use the Refining Unit control panel | Confirms the unit is recognized/operational for the tutorial. |
| Defense setup | Craft → deploy Gun Towers | Towers must be placeable and positioned on markers. |
| Power delivery (next) | Electric Pylon + transmit power from Sub-PAC | Towers need power to function. |
Where “Deploy Gun Towers” sits in the outpost quest
“Deploy Gun Towers at the marked locations” is Step 9 in a longer “Building an Outpost” checklist that starts with combat, then outpost setup, then logistics and verification, and only then moves to defense placement and powering. In that flow, you should already have placed the Sub-PAC, connected belts between the Sub-PAC and a Refining Unit using the correct ports, and confirmed the Refining Unit at its control panel before the tower step appears.
How to build and place Gun Towers so the objective completes
Step 1
Open the Facility List when the quest prompts you and construct the Gun Towers so they become placeable items in your inventory/backpack.
Step 2
Go to the objective area and visually confirm you’re standing inside the marked build zone; the placement spots are fixed and the objective is checking those exact locations.
Step 3
Start placing a Gun Tower and move your cursor/camera until the placement preview snaps onto the marked spot rather than free-placing on nearby ground.
Step 4
Repeat placement on each marked spot until the objective updates (the step can fail if a tower is “near” the marker but not actually on it).
Troubleshooting when it won’t register
If you crafted towers but can’t place them, the most common issue is that the towers were not actually created as placeable inventory items via the Facility List step. If you can place them but the quest won’t progress, re-place them directly on the marked spots and keep adjusting angle/distance until snapping behaves consistently.
What to do right after placement (powering and the next fight)
Right after the tower deployment step, the quest instructs you to power the towers by placing an Electric Pylon and transmitting power from the Sub-PAC to the pylon. The mission then has you withstand another Landbreaker attack as a practical check that your towers are not only placed, but also powered correctly.
Finishing the Gun Tower deployment objective
Craft the Gun Towers from the Facility List, place them as inventory items, and snap each one exactly onto the quest’s marked spots; then move on to the Electric Pylon power-transmission step to make them function in the next fight.
