Diary of a Camper is a short American film made using id Software's 1996 first-person shooter video game "Quake", released in 1996. It was created by United Ranger Films, then a subdivision of a popular group of video game players, or clan, known as the Rangers. The film was first released over the Internet as a non-interactive game demo file. The video is generally considered the first known example of machinima—the art of using real-time, virtual 3D environments, often game engines, to create animated films. The story centers on a lone camper, a player waiting in a strategic location instead of seeking active battle, who faces five members of the Rangers clan in a deathmatch, a type of multiplayer game in which the goal is to kill as many opponents as possible.
