Arc Raiders: How to Complete Avian Alarm Raider Project on Riven Tides – Project Stages, Buoy Locations, and Rewards

What to know

• Avian Alarm is a new Raider project focused on the Riven Tides coastline and buoy‑based bird‑cage deployment.
• It has five distinct stages; each stage is tied to placing or interacting with cages at buoys along the beach and cliffs.
• Main rewards include the Dockmaster’s Detector (required for the Beachcombing mechanic), Gel Patches, the Bird House backpack attachment, the Fist In Air emote, and 250 Raider Tokens.
• Completing Avian Alarm supports the newer coastal content loop and opens up opportunities to farm extra materials and event‑related items on the Riven Tides map.

Avian Alarm is a five‑stage Raider project in Arc Raiders that ties into the Riven Tides coastline, where you build a makeshift bird‑based security system and deploy cages at buoys to progress. Finishing all five stages unlocks the Dockmaster’s Detector plus a handful of cosmetic and utility rewards without needing special events or separate modes.

Arc Raiders Avian Alarm: What it is

Avian Alarm is the latest Raider project introduced with the Riven Tides update, designed to turn the coastline into a kind of makeshift early‑warning system based on birds and atmospheric changes. Instead of purely combat‑driven progression, the project layers environmental objectives—using cages placed on buoys and passive bird‑movement cues—into the normal raid loop on Riven Tides.

The project is presented as a security system that reacts to tremors and shifts in the air, which in practice means you respond to specific buoy‑linked prompts and bird‑related triggers along the shoreline. On the map side, the key locations are the cluster of buoys that run along the Riven Tides beach and near the more exposed cliff edges, where bird‑cage markers appear during active stages.

Avian Alarm locations and buoy setup

The buoys for Avian Alarm are distributed along the Riven Tides coastline, typically near docking points, jetties, and the outer edges of the main beach areas. Some of these buoys sit closer to deeper water, while others are in shallower zones or near submerged structures, so you may need to swim or use cover along the shoreline to reach them without drawing too much ARC attention.

Each stage of the project highlights a small set of buoys that are marked with a project‑specific icon or glow, and you are expected to interact with those spots in sequence. Since the project is linear across five stages, you do not need to hit every buoy on the map at once; instead, you loop through the highlighted ones over multiple raids, letting the project progress as you encounter the correct locations.

How to start and track Avian Alarm

Before you touch bird cages or buoys, Avian Alarm appears in your active Raider projects list in the Riven Tides update. From the main menu or in‑game project board, you can open the project entry to see the current stage along with a brief description of what you need to do next.

Tracking the project mid‑raid is simple: the current stage objective broadcasts on‑screen when you are near a relevant buoy or when the environment triggers a bird‑related cue. If the objective is not visible yet, you either need to wait for a different stage of the project to activate or replay Riven Tides until the system identifies which buoys it wants you to interact with for that stage.

How to complete Avian Alarm

Step 1: Prepare for a Riven Tides raid

• Equip a loadout that can handle both coastal ARC enemies and some mid‑range exposure along the beach.
• Make sure your objective is set to include Riven Tides and that you are not locked into a different map or event that overrides project tracking.

Step 2: Load into Riven Tides and find the coastline

• Once the match starts, move quickly toward the main beach‑side routes that lead down to the shoreline and buoys.
• Look for small clusters of buoys near docks, submerged platforms, and cliff‑edge access points; these are the usual candidates for Avian Alarm stages.

Step 3: Identify the active stage buoy

• Walk or swim near the buoys until your objective marker updates with a project‑specific cue such as “Deploy cage at buoy” or “Observe bird‑cage activation.”
• If nothing highlights, keep moving between different buoy clusters or restart the raid until the game’s logic assigns you a different set of buoys for that stage.

Step 4: Deploy or interact with the bird cage

• At the highlighted buoy, open the interaction prompt for the cage and select the appropriate option (usually “Deploy” or “Activate”).
• The cage will then capture or trigger a flock of birds, which in turn registers progress toward the current stage of Avian Alarm.

Step 5: Repeat for all five stages

• Advance through the five stages by repeating the same general loop: reach the coastline, locate the buoy cluster, interact with the cage, and confirm the stage‑progress notification.
• Each stage may place buoys slightly farther out into the water or closer to different ARC spawn points, so adapting your pathing and using cover or stealth items can help you avoid unnecessary fights while still completing the project.

Avian Alarm rewards

Completing all five stages as a single project run typically grants the full bundle of these rewards, with the Dockmaster’s Detector being the functional centerpiece that lets you engage with the Beachcombing mechanic on Riven Tides.
