Developer Team Cherry announced the free Hollow Knight: Silksong expansion Sea of Sorrow in a recent blog post. It will launch sometime in 2026. A teaser trailer for the expansion was also released. Additionally, the developer announced that the game’s sales have surpassed seven million copies worldwide. Hollow Knight: Silksong is available for PlayStation 5, Xbox Series, Switch 2, PlayStation 4, Xbox One, Nintendo Switch, and PC via Steam, GOG, Humble Store, and Microsoft Store. In the game, players play as Hornet who “must battle foes and solve mysteries as she ascends on a deadly pilgrimage to the kingdom’s peak.”
The expansion’s details:
Heya Everyone!
With Hollow Knight: Silksong’s launch year coming to a close, we wanted to take a moment and share a peek at what we’ve been working on, what’s available now, and what’s coming in 2026.
But firstly, and most importantly, we wanted to say a huge thank you to all the players who’ve braved Silksong’s distant and dangerous lands. That’s over seven million of you who’ve purchased the game, alongside millions more playing on Xbox Game Pass!
It’s a truly staggering number of players, more than we could have ever expected (enough to crash all of the storefronts!). Watching the community grow, seeing the amazing art, the mods, the unexpected strategies, and the support between players through the game’s challenges has been hugely rewarding for us here at home. Your continued enthusiasm remains a massive motivator as we work towards expanding the game even further.
That first big expansion is already well underway! Check out the teaser below for a hint at what’s coming up next.
New areas, bosses, tools, and more! Hornet’s adventures continue in our nautically themed expansion, coming free for all players next year. We’ll keep further details a secret for now, but expect additional info shortly before Hollow Knight: Silksong – Sea of Sorrow releases.
