ARC Raiders: How to Complete Shoring Up Defenses Fast

To complete Shoring Up Defenses in ARC Raiders, you need to do four things on Riven Tides: destroy 5 Wasps, destroy 3 Fireflies, reinforce a Raider structure at Stacking Yard with 1 ARC Alloy, and board up a shuttered window in Hotel Panorama Azzurro. The cleanest route is to handle the hotel first in the west, farm your ARC kills while rotating east, then finish at the Stacking Yard cranes in the northeast. This walkthrough keeps the travel efficient and avoids the two most common time sinks: reaching the crane without ARC Alloy, and searching the wrong hotel room for the board-up prompt.

Shoring Up Defenses objectives at a glance

Shoring Up Defenses is one of the early Quests tied to Riven Tides, and the game lets you complete the objectives in any order across multiple matches. That matters, because this is not a quest you need to force into one perfect run if the lobby turns messy. When you accept it from Apollo, you also receive the Dockmaster's Detector, but that device is separate from the quest steps. If your goal is just to finish Shoring Up Defenses, focus on the four required objectives below and ignore beach-combing detours.

• Destroy 5 Wasps
• Destroy 3 Fireflies
• Use 1 ARC Alloy to reinforce a Raider structure on top of any Stacking Yard crane
• Board up 1 shuttered window in Hotel Panorama Azzurro

If you want the quickest completion, treat the two location objectives as the backbone of your route and pick up the ARC kills naturally while moving between them. Wasps are common enough that they usually finish themselves. Fireflies are the objective that most often drags the quest out, because they are tougher, more aggressive, and not worth hard-chasing through bad sightlines.

What to bring before you deploy

The best preparation is simple: bring 1 ARC Alloy into the raid if you can. That removes the biggest failure point in the quest. If you arrive at the Stacking Yard crane and realize you still need Alloy, you either have to loot one from destroyed ARC targets or cross more of Riven Tides than you planned. On a vertical map with long angles, that often turns a clean quest run into a PvP risk.

For weapons, accuracy matters more than raw DPS. Wasps die quickly if you hit their wing motors, and Fireflies become much easier when you aim at the rear engine area instead of dumping shots into the body. A Hullcracker is especially good for both machine-kill objectives because it punishes weak points hard, but any reliable mid-range gun works if your tracking is steady. Seeker utility is also useful against Fireflies if they start hovering above awkward cover.

• Carry 1 ARC Alloy if possible
• Bring a precise mid-range weapon; Hullcracker is a strong fit
• Keep one inventory slot clear so you do not have to juggle loot mid-run
• Bring enough healing to survive rooftop and stairwell fights
• Do not overload on close-range gear if this raid is mainly for quest completion

Best route: Hotel first, then rotate to Stacking Yard

Riven Tides spreads the two interaction objectives across opposite sides of the map, so the route matters more than the actual interactions. Starting at the hotel is usually safer because the interior objective can become awkward later in the match, especially if other players have already passed through or if the upper floors are hot with ARC pressure. After that, move east and finish your kills on the way to the cranes.

Board up the hotel window at Hotel Panorama Azzurro

Hotel Panorama Azzurro is on the west side of Riven Tides. Enter through the main entrance, then take the left-side stairs upward. The most reliable room reported for this objective is room 213, with the room number posted above the door. When you reach the correct spot, you should get an interaction prompt that lets you board up the shuttered window.

This is the one part of the quest where there is some small disagreement from players. Room 213 is the safest target to check first, but some runs also seem to allow a nearby shuttered window such as room 207 or an adjacent office area with a red roll-down shutter. If 213 does not give you the prompt, do not immediately assume the quest is bugged. Sweep the same floor and nearby rooms before leaving the building.

The hotel can also spawn trouble upstairs, including defensive enemies that make the hallway more annoying than dangerous. The biggest mistake here is overcommitting to a fight in a narrow corridor when all you need is a single interaction. Clear only what blocks the stairwell or your room, finish the board-up, then get back outside. This quest does not reward a full hotel clear.

Farm Wasps and Fireflies while moving east

Once the hotel window is done, use your rotation toward the center and northeast to finish the machine kills. Wasps are the easy half of the quest. They are fragile, show up all over Riven Tides, and drop fast if you shoot the wing motors instead of the center mass. If you are unloading full magazines into their body, you are making them look tankier than they are.

Fireflies are the slower objective. They are more durable than Wasps and much more punishing in the open because of their aggressive fire attacks. The fastest way to bring them down is to aim at the rear engine area and keep lateral movement while using cover breaks. If you have Seeker utility, this is a good place to spend it. Fireflies are not rare enough to require a full map hunt, but they are rare enough that you should take the kill whenever you see one instead of assuming another will appear right away.

Do not tunnel on these kills if they pull you into bad terrain. Because Shoring Up Defenses can be completed over multiple Riven Tide matches, it is often smarter to leave one Firefly unfinished than to sprint across exposed ground and lose the entire run. This is especially true if you are already carrying your ARC Alloy and only need the crane interaction.

Reinforce the Raider structure at Stacking Yard

Stacking Yard sits in the northeast of Riven Tides and is easy to recognize by its three tall cranes. You can reach the top by using ropes, stairs, or nearby ziplines, depending on which side you approach from. The middle crane is a common choice simply because players spot it quickly, but the objective is not locked to one exact crane. The interaction prompt can appear at the summit of any of the crane tops if you find the flimsy Raider structure there.

What you are looking for is a rough shelter made from metal sheets, poles, or tent-like materials at the top platform. If you have 1 ARC Alloy in your inventory, walk up to the structure and use the interaction prompt to reinforce it. The game consumes the Alloy and checks off that part of the quest.

The common mistake here is climbing the crane, seeing industrial props, and assuming none of them are correct. Slow down and circle the top platform. If the prompt does not appear on one crane, move to another rather than dropping off the whole POI. The Stacking Yard objective is much more forgiving than it first looks; most failures happen because players arrive without Alloy, not because the crane location is hidden.

If you did not bring ARC Alloy

You can still complete Shoring Up Defenses without bringing ARC Alloy from Speranza, but the run becomes less consistent. ARC Alloy can be looted from destroyed ARC enemies, so if your Stacking Yard step is still incomplete, start treating suitable ARC fights as part of the route. The key is not to force every engagement. Take fights you can finish quickly, loot the Alloy, then get to the crane before extra noise pulls in more players.

If your only missing step is the crane reinforcement and you have not found Alloy by mid-run, the practical move is often to extract and queue again with one in your bag. That is faster than gambling on more random spawns while crossing a map you already traversed once.

Common problems that slow this quest down

• Shooting Wasps in the body: aim for the wing motors and they drop much faster.
• Trying to burst Fireflies head-on in open ground: break line of sight, then re-peek their rear engine.
• Going to Stacking Yard empty-handed: bring ARC Alloy in advance whenever possible.
• Searching the entire hotel at random: start with the left stairs and check room 213 first.
• Assuming the hotel prompt is bugged immediately: nearby rooms or a nearby shutter may also count in some runs.
• Overfighting upstairs in the hotel: finish the interaction and leave instead of turning it into a full clear.
• Forcing all objectives into one risky match: the quest can be finished across multiple Riven Tides runs.
• Squad confusion on shared interactables: if a teammate triggers the hotel interaction first and your prompt is gone, it may be faster to reset in another raid than to keep troubleshooting in place.

Rewards and turn-in

After you complete all four objectives and extract, return to Apollo to claim the quest rewards. Shoring Up Defenses pays out 3 Barricade Kits, 3 Lure Grenade Traps, and 6 Seeker Grenades. That reward package fits the defensive theme of the quest and gives you solid utility for later Riven Tides runs.

If you want the shortest reliable walkthrough, the formula is simple: bring ARC Alloy, clear the hotel window first, take easy Wasp kills along your rotation, finish Fireflies only when the angle is good, then reinforce a crane-top structure at Stacking Yard and extract. That keeps Shoring Up Defenses efficient instead of turning it into a full-map scavenger hunt.
