H.U.R.L. is a children's game that was released in 1995 by a publishing house called Deep River Publishing. It is a first-person shooter (FPS), and is part of the wave of nonviolent FPS's that followed closely on the release of Doom and other games such as Wolfenstein in the early 90s. It was later re-released as Slob Zone 3D, and then translated to German and released as Blob Schlammschlacht 3D ("Blob Mudfight 3D").
Lacking violence, the game uses surrealism and potty humor to keep its young audience interested. The player finds himself searching each level for bathrooms in the hopes of finding a clean toilet to use to clean himself up after being hit in the face with dirty things such as kitty litter. In the final level the player is located in a nightclub and breaks into a house notably lacking in bathroom facilities, whereupon they meet the game's only boss, who immediately starts throwing diapers. Each time the player splashes the boss he emits a brief fart-like sound. In order that the game be able to earn an ESRB rating suitable for children, no graphic depictions of anything obscene are included.
The artificial intelligence of the enemies has been criticized for being of sub-standard quality . One complaint that players have made is that the enemies often block their path by standing right in front of a door they need to get through in order to complete the level.
The images in the game are mostly digital pictures of figurines created from modeling clay, encoded in an early type of GIF known as GIF87a.
