Pearl Abyss just turned the desert into an ocean. Crimson Desert’s first major DLC, “Charting the Unknown,” has been officially revealed — and it’s not just an expansion. It’s practically a second game bolted onto the already enormous base experience. From full naval combat to underwater dungeon exploration to a romance system that lets you build relationships with key NPCs — “Charting the Unknown” takes everything that made Crimson Desert great and pushes it into uncharted waters. Literally.
Crimson Desert launched on March 28, 2026, to critical acclaim as one of the year’s best action RPGs.

All New Features — The Complete Breakdown
⛵ Naval Combat — Command Your Own Ship
The headline feature of “Charting the Unknown” is a full naval combat system that lets players captain their own vessels, engage in ship-to-ship battles, and explore the open sea.
| Naval Feature | What We Know |
|---|---|
| 🚢 Ship Types | Multiple vessel classes — from small sloops to warships |
| ⚔️ Ship-to-Ship Combat | Broadside cannon battles + boarding mechanics |
| 🏴☠️ Boarding Actions | Grapple enemy ships → melee combat on deck |
| 🗺️ Open Sea Exploration | Sail freely across the new ocean region |
| ⛈️ Dynamic Weather | Storms, waves, and wind affect sailing + combat |
| 🔧 Ship Customization | Upgrade hull, sails, cannons, crew quarters |
| 👥 Crew Management | Recruit NPC crew members with unique abilities |
| 💀 Sea Monsters | Massive creatures attack your ship — boss-level encounters |
| 🏝️ Island Discovery | Find uncharted islands with dungeons, loot, and story content |
The naval combat is being built on Pearl Abyss’s expertise from Black Desert Online’s ocean content — but significantly expanded with Crimson Desert’s action-focused combat engine. Ship battles aren’t just about firing cannons; they transition seamlessly into melee boarding encounters where Crimson Desert’s signature combat system takes over.
🌊 Underwater Exploration — A New Dimension
“Charting the Unknown” introduces a full underwater exploration system:
| Underwater Feature | What We Know |
|---|---|
| 🤿 Diving Mechanic | Dive beneath the waves to explore the ocean floor |
| 🏛️ Sunken Ruins | Ancient temples and cities beneath the sea — full dungeon content |
| 💎 Underwater Loot | Unique materials, treasures, and artifacts only found underwater |
| 🐙 Aquatic Enemies | New enemy types exclusive to underwater zones |
| 🫧 Oxygen System | Breath management — upgradeable through gear + abilities |
| 🔮 Bioluminescent Zones | Glowing underwater areas with unique visual aesthetics |
| 🗡️ Modified Combat | Combat feels different underwater — adjusted physics + movement |
The underwater zones are designed as a completely separate experience from surface gameplay — with their own enemies, loot tables, dungeon designs, and environmental puzzles. Pearl Abyss has described the Sunken Ruins as some of the DLC’s most challenging and visually stunning content.
💕 Romance System — Build Meaningful Relationships
Perhaps the most surprising addition: a full romance system with key NPC companions.
| Romance Feature | What We Know |
|---|---|
| 💬 Relationship Building | Dialogue choices + actions affect relationship status with NPCs |
| 💕 Romance Options | Multiple romanceable NPCs with unique storylines |
| 🎁 Gift System | Give gifts to NPCs to improve relationships |
| 🗣️ Companion Dialogue | Romanced companions have unique dialogue throughout the game |
| 🏠 Shared Activities | Activities like fishing, exploring, and crafting together |
| 💔 Consequences | Romance decisions affect story outcomes and companion loyalty |
| 🤝 Friendship Paths | Non-romantic relationship options also available |
The romance system is described as “meaningful rather than mechanical” — suggesting Pearl Abyss is aiming for character depth rather than simple affection meters. Dialogue choices, quest decisions, and even combat behavior can influence how companions perceive you.
The New Region — The Sunken Straits
| Region Detail | Info |
|---|---|
| Name | The Sunken Straits |
| Type | Ocean + Island Archipelago |
| Biomes | Open sea, volcanic islands, coral reefs, sunken ruins |
| Scale | Comparable in area to the base game’s largest region |
| Access | Available after reaching a certain point in the main story |
| Navigation | Ship-based traversal + diving for underwater areas |
| New Settlements | Port towns on major islands — merchants, quest givers, taverns |
| Main Storyline | New story arc involving ancient maritime civilization |
The Sunken Straits isn’t a small bolt-on zone — it’s described as a massive new region with its own storyline, settlements, and progression path. The combination of surface exploration (sailing between islands), underwater exploration (diving into sunken ruins), and land-based exploration (exploring island interiors) creates a three-layered experience unlike anything in the base game.
New Combat Additions
Beyond naval and underwater combat, “Charting the Unknown” introduces new combat options on land as well:
| Combat Addition | What It Does |
|---|---|
| ⚓ Harpoon Weapons | New weapon class — throwable harpoon with chain mechanics |
| 🐙 Sea Monster Hunts | Multi-phase boss fights against massive ocean creatures |
| 🏹 Ship-Mounted Weapons | Ballistas and cannons usable during ship combat AND land sieges |
| 🌊 Tidal Abilities | New combat abilities themed around water/tidal forces |
| 🤺 Boarding Combat | Unique deck-fighting mechanics — tight spaces, environmental hazards |
The Harpoon weapon class deserves special attention — it’s a hybrid ranged/melee weapon that can be thrown at medium range and then pulled back using chains, dragging enemies toward you. Think of it as a more aggressive, combat-focused version of the grappling hook mechanic, but designed as a full weapon with its own skill tree.
New Progression Systems
| System | What It Adds |
|---|---|
| 🚢 Ship Progression | Upgrade your vessel — bigger ships, better weapons, faster sailing |
| 🤿 Diving Skill Tree | Improve breath time, underwater movement speed, aquatic combat |
| 💕 Relationship Levels | NPCs have trust/affection levels that unlock new content |
| 🗺️ Cartography | Map uncharted islands — earn rewards for discovery |
| 👥 Crew Abilities | Level up your ship crew — each crew member has unique combat/support abilities |
| 🎣 Enhanced Fishing | Deep-sea fishing with new rare catches + materials |
The Cartography system is particularly interesting — the DLC’s title “Charting the Unknown” literally describes a core progression mechanic. Discovering and mapping new islands earns rewards and unlocks new content, encouraging thorough exploration over rushing through the main story.
Sea Monster Boss Fights — The Ocean’s Deadliest Encounters
Pearl Abyss has teased several massive sea creature encounters that serve as the DLC’s signature boss fights:
| Boss Type | Environment | Mechanic |
|---|---|---|
| 🐙 Kraken | Open Sea | Tentacles attack ship — destroy them while avoiding capsizing |
| 🐉 Sea Serpent | Coastal waters | Chase sequence → ship combat → boarding-style melee on its body |
| 🦈 Megalodon | Deep Ocean | Underwater boss fight — oxygen management + combat |
| 🏛️ Sunken Guardian | Underwater Ruins | Dungeon boss — puzzle + combat hybrid |
These fights combine naval combat, underwater combat, and traditional melee combat — sometimes within the same encounter. The Kraken fight, for example, reportedly transitions from ship cannon battle → boarding the creature → climbing its body for a final blow, reminiscent of Shadow of the Colossus-style encounters.
How “Charting the Unknown” Compares to Other Action RPG DLCs
| DLC | Game | Scale | New Mechanics | Comparison |
|---|---|---|---|---|
| Blood and Wine | Witcher 3 | New region (Toussaint) | New mutations, vineyard | Gold standard for RPG DLC |
| The Ringed City | Dark Souls 3 | New areas + bosses | New enemies + weapons | Combat-focused expansion |
| Phantom Liberty | Cyberpunk 2077 | New district + story | Vehicle combat, new skills | Story-heavy overhaul |
| Charting the Unknown | Crimson Desert | New region + ocean | Naval combat, underwater, romance | Most mechanically ambitious |
“Charting the Unknown” is arguably the most mechanically ambitious DLC on this list — adding THREE entirely new gameplay systems (naval, underwater, romance) alongside a massive new region. Most DLCs add a new area and some new items; this one adds new dimensions of play.
The Romance Candidates — What We Know So Far
Pearl Abyss hasn’t revealed all romanceable NPCs, but based on showcase footage and hints:
| Companion Type | Expected Traits | Romance Path |
|---|---|---|
| 🗡️ Warrior Companion | Combat-focused — joins you in battle | Built through shared combat experiences |
| 🧪 Scholar Companion | Knowledge-focused — helps with lore/puzzles | Built through exploration + dialogue |
| ⛵ Navigator Companion | Sailing expert — improves ship performance | Built through maritime adventures |
| 🎭 Mysterious Stranger | Appears at key story moments — unclear allegiance | Built through trust-based story choices |
The romance system reportedly ties into the main DLC story — meaning your romantic choices can influence quest outcomes, companion loyalty during critical moments, and even the ending of the Sunken Straits storyline.

The Bottom Line
“Charting the Unknown” isn’t just DLC — it’s an entirely new layer of Crimson Desert. Naval combat that transitions into boarding melee. Underwater ruins with their own enemy types and progression.

Pearl Abyss isn’t just charting the unknown — they’re redefining what a DLC expansion can be. If the execution matches the ambition, “Charting the Unknown” could stand alongside Blood and Wine and Phantom Liberty as one of the greatest action RPG expansions ever made.
