Hollow Knight: Silksong Expansion ‘Sea of Sorrow’ Announced for 2026

Major Free Expansion Coming to Acclaimed Metroidvania

In exciting news for fans of one of 2025’s most celebrated games, developer Team Cherry has announced that their best-selling and critically acclaimed sequel “Hollow Knight: Silksong” will receive a free expansion in 2026. This announcement marks a triumphant continuation of the Hollow Knight saga, which has captivated millions of players worldwide since Silksong’s September 2025 release.

What to Expect from Sea of Sorrow

The expansion is titled Sea of Sorrow and will include new areas, now bosses, new tools and more. Sea or Sorrow, which will be nautically themed, will be available for all players of Hollow Knight: Silksong. The brief teaser trailer released by Team Cherry hints at underwater exploration and maritime mysteries, staying true to the series’ atmospheric storytelling. Team Cherry says they will keep further details a secret for now, but expect additional info shortly before Hollow Knight: Silksong – Sea of Sorrow releases.

A Massive Commercial Success

The expansion announcement comes on the heels of impressive sales figures. Over seven million players have purchased the game, alongside millions more playing on Xbox Game Pass. It’s a truly staggering number of players, more than the developers could have ever expected (enough to crash all of the storefronts!). This commercial triumph demonstrates the enduring appeal of the metroidvania genre and Team Cherry’s masterful game design.

What This Means for Players

The Sea of Sorrow expansion represents Team Cherry’s continued commitment to supporting their titles with substantial post-launch content, mirroring their approach with the original Hollow Knight. For players who have already explored Pharloom’s dangerous lands, this free expansion offers renewed incentive to return to Hornet’s adventure. With Team Cherry’s track record of delivering high-quality content and the developer’s dedication to polish and detail, Sea of Sorrow promises to be a worthy addition to an already acclaimed title. As 2026 approaches, the Hollow Knight community has much to anticipate.
