Hollow Knight: Silksong is the long-awaited spin-off to the acclaimed 2017 indie Metroidvania, Hollow Knight.

Its release had been anticipated by many for years since being announced in 2019, before finally launching in September 2025. The game was met with critical praise from fans and outlets, even earning several year-end awards, including Best Action/Adventure Game at The Game Awards last week. Now, Team Cherry has revealed what’s next for Hornet with a small but intriguing tease.

The news comes after Hollow Knight: Silksong’s win for Best Action/Adventure Game at The Game Awards 2025. Silksong was up for multiple awards, including Game of the Year, but lost a majority of them to the record-breaking Clair Obscur: Expedition 33. Still, for the amount of hype the title generated and delivered on is huge, and it won’t be surprising that many are pumped for Sea of Sorrow.
