DLC Overview
After Silksong absolutely dominated 2025 with over 7 million copies sold and a Game Awards win, Team Cherry dropped a surprise announcement: Sea of Sorrow, the game's first expansion, is coming in 2026 - and it's completely free.
The expansion is nautical-themed, focusing on ocean, saltwater, and shore environments that were hinted at in early trailers but didn't make it into the base game. Community speculation suggests this is Team Cherry bringing back cut content they didn't have time to finish, similar to how the original Hollow Knight's DLCs expanded on ideas from development.
Quick Facts
- Price: Free for all Silksong owners
- Theme: Nautical / Ocean
- New Save Required: No - continue your existing game
- Difficulty: Expected to be harder than base game
Release Date & Platforms
Team Cherry has confirmed a 2026 release window - no specific date yet. As of March 2026, Team Cherry is still working on Patch 5 for the base game, which they've stated will take several weeks. This means Sea of Sorrow is unlikely to drop in March, but the community is watching closely for any announcement.
Platform Availability

Pro Tip: The DLC will auto-download when released if you own Silksong. No separate purchase or installation needed.
Latest News & Discoveries (March 2026)
The community has been buzzing with new discoveries that point to active DLC development:
Red Coral Gorge Confirmed
On March 12, 2026, Team Cherry confirmed that the Red Coral Gorge - a previously scrapped area from Silksong's development - will be making a return in Sea of Sorrow. This is a huge deal for fans who've been following the game since its announcement, as Red Coral Gorge was one of the most-requested cut areas.
Conductor Mask Removed
In the latest patch, Team Cherry quietly removed the cracked Conductor mask that was previously found in the Blasted Steps area. Fans are convinced this change is directly related to DLC development - the mask may play a different role in Sea of Sorrow's story.
Submarine Cutscene Discovered
Dataminers have found a submarine cutscene hidden in the game files. This suggests a potential new method of transportation for Hornet in the DLC, possibly for navigating underwater areas or reaching new regions of Pharloom.
Patch 5 in Progress
Team Cherry has confirmed Patch 5 is currently in development and will take several weeks to complete. The latest public beta (v1.0.29884) added Traditional Chinese localization and refined the German translation. The ongoing patching shows the game is still receiving active support.
New Areas
Red Coral Gorge (Confirmed)
The newly confirmed Red Coral Gorge is expected to be a major area in the expansion. Originally cut during development, this coral-themed region likely features:
- Vibrant coral reef environments
- Unique sea creature enemies
- Potentially underwater or partially-flooded sections
- Connections to the broader Pharloom lore
Pharloom Bay
The other expected star area is Pharloom Bay, glimpsed in Silksong's very first trailer but cut from the final game. Based on datamined map data, Pharloom Bay sits southeast of Bilewater, above Verdania.
The area has a distinctive bright blue background on the map (likely indicating water) and features:
- Saltwater hot springs
- Metallic and iron architecture
- Wave-themed visual elements
- Shore/beach environments
Other Possible Areas
Community speculation suggests we might also see:
- Snail Village - Another cut area mentioned in early development
- The LAB - A mysterious location linked to Plasmium research
- Underwater sections navigable via the submarine
New Bosses & Content
Team Cherry's teaser confirmed "new areas, bosses, tools, and more." Here's what we're expecting based on community analysis and the Bloodborne-like story structure many fans have identified:
New Bosses
Community estimates suggest 3-6 new bosses themed around sea creatures and nautical elements. Given the confirmed Red Coral Gorge and Pharloom Bay settings, expect bosses inspired by:
- Crustaceans (crabs, lobsters)
- Mollusks (snails, possibly octopi)
- Deep sea creatures
- Potentially Lovecraftian/cosmic horror elements tied to Plasmium
New Tools
The trailer mentions new Tools. These could include water-themed abilities or upgrades to existing mechanics. The discovered submarine cutscene suggests at least one new traversal mechanic. There's also speculation about new Crests.
New NPCs
Expect new characters to meet in the DLC areas, potentially including merchants, quest-givers, and lore-relevant NPCs that expand on Pharloom's history.
Plasmium Connection
Here's where it gets interesting. Lore hunters have pieced together that Pharloom Bay might be where Plasmium was first discovered. The blue substance that powers the Plasmium Phial could have oceanic origins.
Theory: Some community members have drawn parallels between Silksong's story structure and Bloodborne's DLC - both involve descending to coastal/oceanic areas that reveal the true origins of a corrupting infection. The prominent ocean themes in Sea of Sorrow's title and trailer could point to a similar Lovecraftian, cosmic horror revelation about Plasmium's nature.
The expansion could significantly expand on Plasmium mechanics, possibly including:
- New Plasmium-related upgrades
- Expanded Plasmification mechanics
- Lore explaining Plasmium's origins
- New Plasmium sources in the DLC areas
How to Access
Good news: you won't need a new save file to access Sea of Sorrow. The DLC will integrate directly into your existing Silksong game.
Expected Requirements
While not officially confirmed, based on Hollow Knight's DLC pattern:
- Own Hollow Knight: Silksong
- Reach a certain point in the main game (likely after Bilewater)
- Find the entrance to the new areas (probably southeast of Bilewater)
Preparing Your Save
If you want to be ready when the DLC drops:
- Complete the main story (or get close to it)
- Explore Bilewater thoroughly
- Stock up on Rosaries and upgrade your Tools
- Master the Plasmium Phial mechanics
- Beat Lost Lace if you're up for the challenge - the DLC is expected to be even harder
Wrapping Up
Sea of Sorrow is shaping up to be a substantial expansion with confirmed returning areas like Red Coral Gorge and likely Pharloom Bay. The submarine discovery, Conductor mask changes, and ongoing Patch 5 development all point to Team Cherry actively building something big.
The fact that it's free shows their commitment to the community that waited years for Silksong. We'll update this guide as more information drops. In the meantime, focus on mastering the base game and keep an eye on Team Cherry's official channels.
The depths of Pharloom await. Prepare for Sea of Sorrow!
