This upcoming DLC will introduce new areas, new bosses, and new tools to expand Hornet's adventure even further. Below is a simple and easy-to-read list of everything we know about when this update will come and what it will contain.

What Is Hollow Knight: Silksong Sea of Sorrow?

Hollow Knight Silksong Sea of Sorrow, the first major post-launch expansion for Silksong, continues Hornet's story with a series of new levels inspired by water and filled with new enemies and tough environments.

There are no details on gameplay yet, but Team Cherry has confirmed that this expansion will introduce new bosses, player abilities, and hidden secrets throughout the world.

The expansion’s name, Sea of Sorrow, suggests a focus on underwater or coastal exploration. Given Team Cherry’s creative track record, players can likely expect detailed level designs, interconnected environments.

In addition to being a significant addition to the Hollow Knight franchise, this announcement is also exciting because the developers have confirmed that it will be released as a free update to all players.

Hollow Knight Silksong Sea of Sorrow Release Period

So, when is the Hollow Knight Silksong Sea of Sorrow release date? While there’s no exact day confirmed yet, Team Cherry has officially stated that the DLC will release sometime in 2026. The studio teased the expansion with a short trailer and promised that more details about the content and release window would drop closer to launch.

Given their history, Team Cherry usually follows a polished development cycle rather than rushing updates. That means we can expect Sea of Sorrow to release once all features are fully tested and balanced. The announcement also mentioned that the DLC is already well underway, which means a mid-to-late 2026 release seems very likely.

What to Expect from the Upcoming Hollow Knight Silksong Expansion

The Hollow Knight Silksong Expansion will likely include:

• A new region centred around nautical or oceanic environments.
• Brand-new enemies and bosses with distinct attack patterns.
• Additional tools and abilities for Hornet.
• Expanded lore tied to Silksong’s mysterious world.
• Hidden collectibles and surprises to discover for lore hunters.

Since Sea of Sorrow continues Hornet’s journey, it might also address some lingering questions from the main story. Fans can expect the same detailed world-building, haunting music, and challenging gameplay that made both Hollow Knight and Silksong fan favourites.
