Hollow Knight: Silksong is one of the most anticipated Metroidvania games from Team Cherry. It is a sequel to their highly acclaimed and commercially successful first game, Hollow Knight.
It was revealed in February of 2019 during a Nintendo Switch Direct. It's planned to be a timed-exclusive for the Nintendo Switch console.
The gameplay of Silksong will be similar to the original Hollow Knight, although with some changes adopted for the new heroine of the story, Hornet.
Hornet was originally planned to be a DLC for Hollow Knight. However, the content and scope became too large that the team decided to make a sequel out of it.
