Hollow Knight: Silksong – Sea of Sorrow Expansion Announced for 2026

The nautical-themed expansion will be free for all players and add new bosses, tools, and areas for the acclaimed Metroidvania.

Posted By | On 16th, Dec. 2025

When Team Cherry confirmed it was working on new content for Hollow Knight: Silksong, there was concern that there would be another long wait. Fortunately, that doesn’t seem to be the case, as it announced Sea of Sorrow, a free expansion coming next year. Check out the first teaser trailer below.

Details are scant at the moment, but it’s nautically themed and will feature new areas, tools to discover and bosses to fight. Team Cherry is currently keeping things under wraps, but it has interestingly noted that you can expect “additional info” before launch. Which means the next time we hear about Sea of Sorrow could be right before it’s available, in classic Team Cherry fashion.

In the meantime, for those who waited years for the Metroidvania, reset the clock.

Hollow Knight: Silksong is available for Xbox Series X/S, PS5, PC, Nintendo Switch, Nintendo Switch 2, Xbox One and PS4. It’s also available on Game Pass. Check out our review for the base game.
