ARC Raiders Riven Tides Loot: Hotel Key Chain and Crane

Riven Tides unlocks at 20 rounds and is the Difficulty 5 map: a flat coastal resort with very high verticality, a tide-and-flooding cycle, and an aerial ARC boss. Its headline loot is “Panorama relics,” and most of the good stuff hides in keycard rooms you chain off each other. The tactics page covers the fight; this page is the loot map.

The Hotel Panorama Azurro keycard chain

Hotel Panorama Azurro is the money route. Its keycard rooms are the core loot loop, and the safe inside a room can drop the next hotel key, so one key can run several rooms in a single raid.

Confirmed rooms and what they open:

• Hotel Keycard No. 107 — drops from the Battening Down quest, random drops, Beachcombing treasure, or Hotel Room 102. Opens Room 107.
• Hotel Keycard No. 102 — random drops, Beachcombing treasure, or Hotel Room 107. Opens Room 102.
• Hotel Keycard No. 208 — found inside Rooms 102 or 107. Opens Room 208 on the second floor: a two-story room stacked with weapons, containers, medical loot, and high-value gear.

Community testers also report Rooms 113, 205, and 311 with strong safe and blueprint rolls, but 102/107/208 are the agreed backbone.

Run order: open safe rooms first (102, 205, 113, 311, 107), check each safe for a chaining key, then open Room 208 last as your loot finish. Extract with weapons, blueprints, and spare keys — do not get greedy after 208.

Port Authority: Classified Records into Secure Storage

The Port Authority Building holds the second key chain. The Classified Records Keycard opens one of two doors on the top floor (kill the Shredders first). Inside is the Secure Storage Keycard, which opens the deeper room — better tech loot and better containers. This is a two-key investment, so only carry both if Secure Storage is your target. The roof above also has boxes and sightlines worth a quick scout.

Stacking Yard: the Crane puzzle

The Crane House Keycard (random drop or Beachcombing treasure) opens two doors to the same loot room in the middle-southern Stacking Yard building. Getting there needs the on-site puzzle: four buttons hidden across the crane zones (middle crane office, puzzle crane, upper walkway, lift/bush zone). Once all four are pressed, the first room opens.

For the battery room past it, the intended method needs two players — one rides the lift, one holds the button. Solo method: find the battery near the crane puzzle, drop it under the structure, climb above, Snap Hook it up, and slot it in. Inside: lockers, a gun case, drawers, and a breachable container.

Where each material lives

• Hotel — guest-room scavenging (residential items, keycards).
• Stacking Yard — Exodus and Industrial cargo.
• Port Authority — Technological loot.
• Customs House — Electrical parts; its underground area is reached by the east-side ziplines.
• Dried Riverbed — nature-related resources.

Events that change the run

Riven Tides runs the standard condition rotation plus coastal events. The ones that matter for loot:

• Beachcombing — the map’s signature event (patch 1.26.0); treasure spawns that can carry keycards.
• Night Raid — increased loot value, but fewer return points and no raider hatches.
• Lush Blooms — nature-loot weather.
• Plus Uncovered Caches, Prospecting Probes, and Husk Graveyard on the normal rotation.

The container guide lists what each crate pays, and the night raid guide covers the value buff.

The tide cycle

Riven Tides alternates low and high tide. Low tide exposes hidden caves, submerged tunnels, and wrecked infrastructure with high-value caches — the contested window everyone targets. High tide floods low zones and pushes fighting onto rooftops, hotels, and cliff paths. Time your route to the tide, not just to proximity.

The five extracts

Named return points: Seaside Elevator and Customs Elevator (no key), plus Saltswept Hatch, Weighbridge Hatch, and Hilltop Hatch (these need a Raider Hatch Key brought from Speranza). Seaside Elevator is the fastest exit from the main loot zones but draws heavy ARC and PvP on night raids.

The keycard guide maps every door, and the maps guide places Riven Tides last in the unlock order.
