Sir, You Are Being Hunted is a first-person stealth survival game set in a sandbox environment inspired by the British countryside. The world is procedurally generated and consists of five islands. The theme of each island can be defined. The themes are rural, fens, mountain and industrial. The character can use a boat to travel between them. To complete the game a set amount of mysterious fragments needs to be returned to a central location with standing stones. That is also the only place the game can be saved, next to when entering a boat.
