Eric Barone, known as ConcernedApe, the creator of the popular indie hit Stardew Valley, has appeared in Hollow Knight: Silksong. His name is listed in the "Additional Character Voices" section of the game's credits.
The Silksong credits are available through the Extras section on the game's start screen. A screenshot showing Barone in the list was published by Team Cherry.
Cole Medeiros, Head of Operations and Business Development at ConcernedApe LLC, confirmed that it is indeed Eric Barone, the creator of Stardew Valley. However, neither he nor Barone reveal which character the creator voiced – "better not to say, so as not to spoil the surprises for the players," Medeiros noted.
The connection between Stardew Valley and Silksong is not limited to voice acting. Matthew Griffin, who is responsible for marketing and PR for Silksong, previously performed a similar role for Stardew Valley, according to information on the Team Cherry website.
