A symbol of unity i ARC Raiders is a quest by Celeste, who asks players to raise a flag in an outpost on the Dam Battlegrounds. The mission gives players an insight into how big a role hope plays in humanity's fight against the ARC invasion. To complete the quest, visit the Formicai Outpost and find the raider flag, then hoist it onto a platform that overlooks Red Lake. Here is a complete guide that will walk you through the mission and help you complete it.
Where to find and raise the Raider flag in ARC Raiders (A Symbol of Unification)
After starting A Symbol of Unification in ARC Raidersplayers must head to the Formicai Outpost i southernmost part of the Dam Battlegrounds map. The area is practically on the edge of the map, so you'll have to do some traveling to get there (unless you're playing nearby). Be sure to keep an adrenaline shot or two to restore your stamina while heading towards the location.
Once you've reached the Formicai Outpost, you'll see a big rusty tower on top of a hill. Since there is no direct entrance to the outpost, you have to take either the winding road on the left or right side to enter it.
As soon as you enter the Formicai Outpost from the back, you'll find a bed to the right with a yellow backpack on it. Search the backpack to retrieve a Raider Flag from it. This will complete the second objective of the A Symbol of Unification quest in ARC Raiders. Now you just have to do it raise the flag on a platform overlooking Red Lake.
To raise the Raider flag in the A Symbol of Unification quest, you must enter the main tower and go through the doorway marked in the picture above.
When you step out onto the platform, you have a clear view of Red Lake. Look to the left to find one flag pole that you can hoist the Raider flag on. Hoisting the flag on the pole will complete the mission.
Now you can safely extract from the Dam Battlegrounds map and return to Speranza. Players will get one Aviator Outfit, 3x Mod Components and 5x Duct Tape as a reward for completing the quest A Symbol of Unification ARC Raiders.
