Hollow Knight: Silksong was announced with a trailer all the way back in 2019 and very little has been revealed by Team Cherry since. After the slow-burning success of the original Hollow Knight in 2017, the title has become one of the most recognizable faces of the indie game scene. It also helped with a renaissance of the Metroidvania genre, spawning dozens of Hollow Knight clones that have tried to capture the essence of a proper sequel, but no one can quite do it the same way Team Cherry did in 2017.
