The Visitor is the character the player controls in Captured.
She is a woman who fell into an underground complex in the woods before being sedated and kidnapped to be submitted to a series of death traps while hunted by blind cannibal Damien Clyde, as explained by the voice over the speaker. The voice constantly refers to her as merely "visitor".
Very little is known about the visitor, although the voice mentions that she's barefoot so it's easier to sneak around Clyde. She is killed after three attacks from Clyde. Her thoughts are occasionally displayed in text, like when she looks at a toilet and says "Of all places..." while looking for the first lever. She screams when attacked and if she opens the fridge to find severed body parts in the first room.
