Shoring Up Defenses is one of the newer quests in ARC Raiders on the Riven Tides map. While a few tasks are direct and require you to take down specific ARCs, completing the rest will require you to travel to specific locations.
This guide will help you complete all the steps.

ARC Raiders Shoring Up Defenses quest walkthrough
The Shoring Up Defenses quest can be broken down into the following parts
- Destroy five Wasps
- Destroy three Fireflies
- Use 1 ARC Alloy to reinforce the Raider structure on top of any Stacking Yard crane
- Board up shuttered windows in the hotel
Destroy five Wasps
This is a pretty simple task since the Wasps are easy targets. You can find them all around the map, and you can shoot them down by targeting their motors on the wings. You can use weapons like a Hullcracker to one-shot them if you want to save time.
Destroy three Fireflies

Fireflies are one of the newer enemies added in previous updates. They’re flying ARCs who are more dangerous than Wasps or Hornets. If they get close, they will try to set you on fire. These are bigger ARCs that have more health points (compared to Hornets), but the strategy is the same.
Target the motors on the rear engine to disrupt its flight, making it easier for you to shoot them down.
Use 1 ARC Alloy to reinforce the Raider structure on top of any Stacking Yard crane

For this part, you’ll need one ARC Alloy, which is easy to find (just look for any destroyed ARC). You can also bring it with you from Speranza. Go to the Stacking Yard POI, and take the rope to reach the top.
On top, you’ll find several cranes. Reach anyone, and you’ll get the prompt to repair it with the ARC Alloy. This will complete the third task.
Board up shuttered windows in the hotel

For the final task, head to the Hotel Panorama Azzurro. Enter through the main entrance, and take the stairs on your left to reach the first floor. Go straight, and you’ll find a room to your left. Inside, you’ll find a red window with a prompt to board it up.
Once done, wooden planks will cover the window, and you’ll finish the final task of the Shoring Up Defenses quest.
