About the game
Project II: Silent Valley tells a mostly linear story set in a partially open dystopian world, told through visual-novel presentation. You take on the role of US Navy officer Hierophan, who teams up with a gentle humanoid weapon named Osprey to expose a conspiracy tied to Silent Valley, an underwater facility, along with the truth behind what happened to his missing friend Ochira. GoldenBlade develops and publishes the game, out since 2026.
