Celeste’s “A Symbol of Unification” is a straightforward vendor side quest in ARC Raiders, but reaching the correct location can take some time if you do not know where to look. The objective revolves around collecting ARC Raiders Items while traveling through the Dam Battlegrounds map, finding a hidden Raider Flag, and raising it at the Formicai Outpost. With a clear route, the entire task can be completed efficiently during a single raid.

Accept the Quest and Enter the Dam Battlegrounds

Start by visiting Celeste at the base in Speranza and accepting “A Symbol of Unification.” Once the quest is active, prepare your preferred loadout and deploy into Dam Battlegrounds. Since the destination is located toward the southern portion of the map, bringing equipment that supports mobility and survival can make the trip more comfortable.

After entering the raid, avoid spending too much time searching unrelated areas. The main goal is to reach Formicai Outpost, so following a direct route will reduce unnecessary encounters and conserve supplies for the return journey.

Locate the Formicai Outpost

Formicai Outpost can be found near the far southern edge of Dam Battlegrounds. The location sits deep within the forest below the Scrap Yard, making it easy to overlook when moving through the area quickly.

Keep an eye out for a large dome-shaped bunker standing by itself on top of a small hill. Its distinctive structure makes it the most useful landmark when approaching the objective. Once you identify the dome, move toward the building and enter from the southwestern side.

Taking a moment to check your surroundings before entering is worthwhile. Other players or hostile threats may still be nearby, and the quest objective itself does not require you to rush blindly into the building.

Search the Medical Bed for the Flag

After entering the main structure from the southwest, proceed carefully. The Raider Flag is not placed in an obvious display area, so knowing the exact search point saves considerable time.

Look immediately to your right after entering. You should find a gray-and-yellow backpack resting on a medical bed. Interact with and loot this backpack to obtain the Raider Flag. Once collected, the flag will be added to your inventory and the next part of the quest can be completed at the nearby exterior platform.

There is no need to search the rest of the building for another item. Once the flag has been secured, focus on reaching the flagpole.

Raise the Raider Flag

With the Raider Flag in your possession, walk straight through the cylindrical room toward the northeast exterior balcony. The route is relatively short, so there is little reason to wander through additional rooms.

When you reach the small balcony, look toward the left side of the platform. The area overlooks Red Lake, and the flagpole can be interacted with from this position. Activate the interaction to hoist the tattered Raider Flag and trigger the quest objective.

Once the objective registers as complete, the field portion of the mission is finished. You can then leave the area and make your way back to Speranza.

Collect the Quest Rewards

Return to Celeste at the base after completing the flag objective. Speaking with her will allow you to turn in “A Symbol of Unification” and receive the listed rewards. The completion package includes the Aviator Outfit in the Dusted Cream color variant, three Mod Components, and five Duct Tape.

For players planning their next raid, these rewards can provide useful additions to their collection and crafting resources. The quest itself is also a good example of how ARC Raiders mixes exploration with compact objectives, encouraging players to learn landmarks and map routes rather than simply following a marker.

Make the Return Trip Efficient

After raising the flag, prioritize a safe extraction rather than continuing to explore without a purpose. The southern forest and nearby areas can contain unexpected threats, and losing the collected rewards after completing the objective would make an otherwise simple mission unnecessarily frustrating.

If your main goal is to finish the quest quickly, keep your route focused: accept the mission, deploy to Dam Battlegrounds, travel to the dome-shaped Formicai Outpost, loot the backpack beside the medical bed, raise the flag on the northeast balcony, and return to Celeste. Players who want to prepare additional resources before their next run can also buy ARC Coins through their preferred in-game or supported purchasing options.
