Years after a children's show has ended, the studio begins broadcasting again. Players control a repairman named Gordon sent to investigate the signal. When now-sentient puppets from the show attempt to hunt down and kill Gordon, players must evade or defeat them while solving puzzles. Defeated puppets revive when players re-enter a room unless Gordon's limited supply of duct tape is used to permanently incapacitate puppets. Gordon can find and use several improvised weapons, such as a shotgun.
