ARC Raiders Riven Tides Hotel Key Room Guide: Room 107, Room 208, and the Epic Double-Key Secret

Riven Tides hides one of the most elaborate key room chains in ARC Raiders — and most players walk right past it. Here's how the hotel key system works, how to unlock it for free via quest, and what to expect inside the double-key epic room.

The Riven Tides Hotel: More Than It Looks

At first glance, the hotel on Riven Tides looks like a straightforward loot location. Standard rooms, some containers, maybe a few suitcases. Nothing that screams "farm this obsessively."

But the hotel is hiding a layered key room system that chains multiple locked areas together, and at the end of that chain sits a double-key epic room that requires spending two separate key cards just to access. It's one of the most intricate loot room setups in the game, and understanding how it works is the difference between walking past thousands of coins in potential loot and extracting heavy.

This guide breaks down the full chain: how to get Room 107 key for free, what's inside Room 107 and the hidden Room 208 it leads to, how the volcanic rock mechanic works, and whether the double-key epic room at the end is actually worth the two-key investment.

Step 1: Getting the Room 107 Key — The Quest Method

The Room 107 key card is obtainable for free by completing one of the new Riven Tides quests. It's a straightforward multi-step quest with three objectives, all located on the Riven Tides map:

Investigate a specific pipe at a designated area of the map
Take a picture of a specific wall at a designated area of the map
Investigate seaweed underneath the hotel beach

Complete all three objectives in a single session, and the quest completes, rewarding you with the Room 107 key card. None of the three steps involve combat, high-risk locations, or expensive resources. It's one of the most accessible key unlocks in the game, which makes it an easy first run for anyone exploring Riven Tides for the first time.

Important note: The exact map positions for the pipe, wall, and seaweed objectives are shown in the source video. If you're struggling to locate them, watch the original footage for precise map markers. The steps themselves are simple once you have the coordinates.

Step 2: Inside Room 107 — What You'll Find (And What's Hidden)

Room 107 looks unassuming on entry. A few suitcases, some containers - standard hotel room fare. But don't just loot the obvious containers and leave. The real value in this room isn't visible at a glance.

Check under the bed.

Underneath the bed in Room 107, there is a security box. Inside that security box: the Room 208 key card - a completely separate key that unlocks an entirely different area of the hotel. This is the core mechanic of the chain. Room 107 doesn't just reward you with loot; it rewards you with access to the next room.

There is one catch: the security box isn't always guaranteed to have the Room 208 key. Sometimes when you open Room 107, the box contains a volcanic rock instead of the key. More on what that might mean shortly.

Step 3: Room 208 - The Hidden Two-Story Loot Room

Take the Room 208 key upstairs and unlock it. What you find inside is a significant step up from Room 107, a two-story room with substantially more containers, heavy on medical loot, and noticeably more valuable per container than the standard room below.

Here's the detail that catches most players off guard: when you find the door on the upper floor of Room 208, it looks exactly like it leads back out to the hotel hallway. It doesn't. That door is still part of the locked 208 area. Open it.

Behind that upper floor door: an additional hidden room connected to the 208 key chain, containing:

Weapons and weapon boxes strewn across the floor
Grenade storage in server cabinets
Additional containers not visible from the main 208 entrance

The lore interpretation, based on the contents and layout, is that this interconnected set of rooms represents a hidden raider camp inside the hotel, stocked, secured, and locked away behind a chain that most players don't know to follow. Whether that's intentional narrative design or a happy coincidence of the loot distribution, the result is the same: following the chain from 107 to 208 to the hidden back room yields substantially more loot than treating the hotel as a casual walk-through.

The Volcanic Rock Mystery: What Does It Mean?

Here's where the Riven Tides hotel gets genuinely interesting from a systems perspective.

When Room 107's security box doesn't contain the Room 208 key, it contains a volcanic rock. At first encounter, this seems like a joke. Someone's pet rock left behind. But this wasn't an isolated observation.

The same volcanic rock appeared in the Room 208 safe when that room was accessed separately (via a random key drop, not the Room 107 chain). Two different hotel rooms. Two different safes. Both containing volcanic rocks as their secondary item.

This suggests something deliberate in the design. The current working theory:

Hotel key rooms have a tiered secondary loot mechanic. The safe or secondary container inside a key room has a chance to contain either a volcanic rock (the consolation outcome) or a further key card that unlocks the next room in the chain (the jackpot outcome). The key isn't guaranteed. It's a roll. Get lucky, and you're progressing deeper into the chain. Get unlucky, and you're looking at a rock.

This means there may be more hotel key rooms on Riven Tides beyond 107 and 208 that haven't been fully mapped yet. The rock appears wherever the chain could continue but the RNG didn't deliver. Players are actively exploring this; if you find a hotel key room that contains a volcanic rock in its secondary container, it may be part of this same chain mechanic.

What to do with a volcanic rock: Its practical in-run use hasn't been confirmed beyond the thematic interest. For now, treat it as confirmation that you rolled the wrong outcome on the secondary loot table, not as an item with crafting or quest value. That may change as more is discovered.

The Double-Key Epic Room: Is It Worth Two Keys?

Here's the most complex part of the hotel key chain, and the one that requires the most deliberate decision-making before you commit.

The Setup

Somewhere on Riven Tides, there is a common key room that serves as a gateway to an epic tier key room. The common key unlocks an area that contains a purple (epic tier) key card inside. To access the epic room, you first spend the common key to get in, then spend the purple epic key to open the final room. Two keys, one room.

First Room Loot (Common Key)

The common key room itself contains a reasonable haul for its tier:

Door blockers
A Photoelectric Cloak
Explosive mines
A mix of standard industrial items, meds, and wires
Multiple breachable containers — a notably high volume
A secure storage key (found inside the room, usable for a further area)

For a green (common) key, the room performs well. The breach density alone justifies the key cost.

The Epic Room: What's Actually Inside

After burning both the common and epic keys to access the final room, here's the honest first-impression verdict: it's variable, and the first run is likely to disappoint.

The room has a large number of containers, eight or more were observed in a single run, with additional containers confirmed to not have spawned that session. The loot pool includes:

Explosive compounds (multiple)
Standard industrial components (wires, processors)
Level 2 weapons (specifically, multiple level 2 Torinos)
Potentially augment blueprints — not confirmed in the first documented run, but the room's container count and type strongly suggest the blueprint pool is active here

The first run produced no augment blueprints and level 2 weapons as the primary drops. For a room that costs two separate key cards to access, that's a frustrating outcome.

The Honest Verdict: Volume Farming, Not Single-Run Jackpot

The epic double-key room should not be evaluated on a single run. Here's the comparison that reframes it correctly:

The Security Checkpoint on Stella Montis is a well-known augment blueprint farming spot. One run through that room with no blueprint feels worthless. But across ten runs, you're reliably pulling multiple augment blueprints. The per-run drop rate only looks good at volume.

The Riven Tides double-key epic room operates on the same principle. Based on the container count and type, it's almost certainly a blueprint room, meaning augment blueprints are in the loot table, but they're not guaranteed per visit. The room is designed for players who run it repeatedly, not for a single-session payout.

Across ten runs of this room, you would likely see several augment blueprints surface. One run with nothing special is expected variance, not evidence the room is bad.

What the Room Demands

The honest caveat is that this room has a real cost barrier that the Security Checkpoint on Stella doesn't have in the same way: you're spending two keys per run, not one. The common key used to get into the gateway area and the epic key for the final room are both consumed every time. The key acquisition cost needs to factor into your expected return.

If you can farm both keys efficiently as part of your normal Riven Tides runs, the epic room becomes a consistent blueprint farming target. If keys are a bottleneck, the room becomes much harder to justify running repeatedly.

How the Full Hotel Key Chain Works: Summary

Putting the whole system together:

The Quest Chain:

Complete the Riven Tides quest (investigate pipe, photograph wall, investigate beach seaweed)
Receive Room 107 key
Enter Room 107 — loot the containers, check under the bed
Security box contains either Room 208 key (jackpot) or volcanic rock (re-roll)
If Room 208 key obtained: head upstairs, unlock Room 208
Loot the two-story Room 208, including the hidden back room behind the upper floor door
Check Room 208's secondary container for a potential further key or volcanic rock

The Double-Key Epic Chain (Separate from the 107/208 Quest Chain):

Find or farm the common Riven Tides key for the gateway room
Use common key to unlock the first room — loot all containers, pick up the purple epic key inside
Use epic key to unlock the final epic room
Loot all containers (high container count, blueprint loot table active)
Extract — repeat at volume for consistent augment blueprint drops

What We Still Don't Know

The hotel key system on Riven Tides is still being actively explored by the community. Several open questions remain:

How many hotel key rooms exist? The volcanic rock secondary mechanic suggests the chain could extend beyond 107 and 208. Players finding hotel keys via random drops are encouraged to check every safe and secondary container in those rooms for further keys.

What determines whether you get a key or a volcanic rock? This appears to be RNG-based rather than condition-based, but nothing has been confirmed. It's possible there's a player-count, server state, or session-specific variable at play.

Does the volcanic rock have any use? It's appeared in multiple hotel rooms now and seems significant by design. Whether it feeds into a quest, a crafting recipe, or is purely a cosmetic joke item remains unconfirmed.

Are there hotel key rooms with better loot pools? The epic double-key room's level 2 weapon drops were disappointing for the tier. It's possible other hotel rooms on the chain have better weapon tier thresholds, or that the blueprint drop rate justifies the result better than a single-session test revealed.

If you've found a hotel key on Riven Tides - common or epic - check every container, every safe, and every secondary slot before extracting. The chain may go deeper than anyone has fully documented yet.

Final Tips for the Riven Tides Hotel Key System

Do the quest first. Room 107 is a free key via a simple three-objective quest. There's no reason not to have it in your inventory on every Riven Tides run.
Always check under the bed in Room 107. The security box is easy to miss if you're looting quickly. Don't skip it.
Don't pass through Room 208 quickly. The upper floor door that looks like a hallway exit is still part of the locked area. Open it. There's a full hidden room behind it.
Treat the epic double-key room as a multi-run farm, not a one-time jackpot. Volume is how this room pays off, not single-session luck.
Always check secondary containers and safes in any hotel key room. The volcanic rock/key mechanic may be present in more rooms than the two documented so far.
Hold onto common keys if you're going for the epic room. You need both the common gateway key and the purple epic key per run. Make sure you have both before committing to the chain.

The Riven Tides hotel is one of the most deliberately designed loot systems in ARC Raiders, a chain that rewards curiosity, punishes players who loot carelessly, and has enough unsolved mystery remaining that the community hasn't fully cracked it yet. The more players explore it and share what they find, the clearer the full picture will become.
