Formicai Outpost in Arc Raiders sits on a high ridge at the very edge of Dam Battlegrounds, which makes it easy to spot but slightly awkward to reach. A Symbol Of Unification sends you here with a simple goal: find a Raider Flag inside the outpost and hoist it on a nearby pole.
The entire quest plays out in a small space, but the combination of steep terrain, narrow trails, and a compact interior means it is still easy to get turned around. The steps below walk through how to get to the outpost, where exactly the flag is stored, and the precise spot where you raise it.
Formicai Outpost location in Dam Battlegrounds
Formicai Outpost is part of the Dam Battlegrounds map, in the Formicai Hills region at the far south. On the tactical map, you need to zoom all the way in on Formicai Hills; the outpost marker appears in the southernmost section, right against the map border.
You will typically travel past loot-heavy areas like the Wreckage or Scrap Yard on your way there, and those zones can attract other players. The hill that supports Formicai Outpost stands out thanks to a tall, rusted tower structure visible from a long distance across Red Lake and the surrounding lowlands.
| Detail | Formicai Outpost specifics |
|---|---|
| Map | Dam Battlegrounds |
| Region | Formicai Hills |
| Position | Southern edge of the map, overlooking Red Lake |
| Landmark | Large rusted tower on top of a steep hill |
| Quest use | A Symbol Of Unification (Celeste) |
Formicai Outpost itself is not a major hotspot, but the approach routes can be busy. You do not have to extract to complete A Symbol Of Unification, so running a free loadout is a safe option if you expect resistance on the way in or out.
How to climb up to Formicai Outpost
The outpost sits on a plateau that cannot be scaled by running straight up the rock face. You have to find the narrow trails that wind up the sides of the hill.
From the base of the hill in the southern Formicai Hills:
- Move around the perimeter and watch for dirt paths that zig-zag upward rather than sheer slopes.
- Look for small wooden planks and walkway segments on one of the trails; these indicate the correct route near the top.
- Follow the trail with planks all the way until it levels out at the top ridge and leads directly to the outpost structure.
Once you crest the final segment, the tower and the low, bunker-like building of the outpost are directly ahead. From here, your main concern shifts from traversal to watching for nearby raiders in the dense cover around the hilltop.
Where to find the Raider Flag inside Formicai Outpost
The first objective in A Symbol Of Unification at Formicai Outpost is to locate the Raider Flag. The flag is not visible in the world until you interact with a specific bag inside the structure.
To get it:
- Enter the outpost through the slim, dark hallway on the ground level of the building at the base of the tower.
- As you step inside, turn your camera to the right side of the corridor.
- A bed (or medical cot) is positioned there with a yellow backpack or bag resting on top.
- Interact with the bag marked by the yellow interaction icon to spawn and collect the Raider Flag.
After the interaction, the Raider Flag is added to your inventory for the duration of the raid. You can confirm this by opening your inventory menu and checking for the flag item.
How to hoist the Raider Flag at Formicai Outpost
With the Raider Flag in your inventory, the final objective is to raise it on the outpost’s flagpole. This happens just a few steps away from where you picked it up.
Use the building’s layout as a reference:
- From the bed and backpack, turn back toward the hallway and walk forward into the circular open area at the core of the outpost.
- Facing out of the hallway, go straight ahead to the doorway that opens to the outside platform on the tower side.
- Step through this doorway onto the exterior platform that overlooks Red Lake.
- Immediately look to your left: a flagpole here is marked with an interaction symbol.
- Interact with the pole to hoist the Raider Flag and complete A Symbol Of Unification.
| Step | Action | Visual cue |
|---|---|---|
| 1 | Leave the flag room | Return to the circular interior area |
| 2 | Head to exterior door | Doorway directly opposite the entrance hallway |
| 3 | Step onto platform | Clear view of Red Lake |
| 4 | Approach flagpole | Pole on the left with interaction icon |
| 5 | Raise the flag | Quest completes when interaction finishes |
Once the flag is raised, the quest objectives update to show completion. From here, you can either keep looting the outpost and nearby containers or move toward an extraction point. The Red Lakes Balcony lift to the northeast is usually the closest exit, but it can be watched by other squads, so sprinting out with low-value gear still makes sense if you want to avoid unnecessary losses.
Back in Speranza, turning in A Symbol Of Unification awards the Aviator outfit along with some extra rewards, and Formicai Outpost remains a useful, relatively quiet high-ground loot spot overlooking the southern edge of Dam Battlegrounds.
