Hollow Knight: Silksong may receive more free DLC, while Sea of Sorrow is described as a giant expansion. Team Cherry announced the nautical expansion in December 2025 as a free release for all players.
The scope description appears in the manual supplied with the physical edition. Some players received copies before the scheduled November 10 arrival date. The standard edition also includes a hand-drawn map and reversible cover art.
What Sea of Sorrow has planned
Sea of Sorrow continues Hornet's adventures across and beneath a salt-stricken ocean. Team Cherry has teased:
- New areas to explore.
- New bosses.
- New tools.
The studio said it would keep further details secret until shortly before the expansion releases. Sea of Sorrow does not yet have a firm release date.
Where further free DLC could fit
Silksong itself began as an expansion for the original Hollow Knight before growing into a full sequel.
The original Hollow Knight received four free content packs: Hidden Dreams, The Grimm Troupe, Lifeblood, and Godmaster. Together, those releases added bosses, items, areas, storylines, and arena challenges.
Team Cherry outlined plans for post-launch support in 2025, ahead of the Sea of Sorrow reveal. Earlier comments from the studio's Ari Gibson and William Pellen suggested Silksong could receive a similar variety of additional content.
