Hollow Knight: Silksong – Sea of Sorrow Expansion Revealed, Nintendo Switch 2 Edition of Original Hollow Knight Also in Development

Hollow Knight: Silksong‘s first big expansion has been revealed by developer Team Cherry.

Teased for 2026, Hollow Knight: Silksong – Sea of Sorrow promises new areas, bosses, and tools as “Hornet’s adventures continue in our nautically themed expansion, coming free for all players next year.”

Further details are expected shortly before its launch, with no specific date given. This shouldn’t come as too much of a surprise, as Silksong’s initial release date wasn’t announced until just a month before it dropped after one of gaming’s most infamous drawn out affairs.

Alongside the announcement of the DLC, Team Cherry also revealed that a Nintendo Switch 2 Edition of the original Hollow Knight is in development. This improved version incorporates “all the updates and enhancements that Silksong received on the platform: high frame-rate modes, higher resolutions, and many additional graphical effects.”

The even better news? If you already own Hollow Knight on Switch, you’ll be able to upgrade to this new gen version for free.

The Australian studio will also be updating all current versions of the original Metroidvania soulslike and adding features and bug fixes. If you’re playing on PC, some of those changes have already come into effect.

“PC players can experience many of those updates right now, via the public-beta branches on Steam and GOG, where they’ve just gone live,” a Team Cherry blog post states. “That includes full 16:10 and 21:9 aspect ratio support for those of you with Steam Decks or ultrawide monitors.”

As part of the DLC announcement, Team Cherry said Hollow Knight: silksong had sold more than 7 million copies since going on sale in September, and had 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!),” Team Cherry said. “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.”

Now seems like as good a time as any to get into both Hollow Knight games, then. IGN’s Hollow Knight review returned a 9.4. We said: “Hollow Knight’s rich world and incredible depth of content will make you want to explore its caves for dozens of hours.”

Similarly, IGN’s Hollow Knight: Silksong review scored the game 9/10. We said: “Hollow Knight: Silksong is packed full of sharp platforming, enticing exploration, and nail-biting combat that’s all unapologetically challenging in just the right way.”
