What is "h.u.r.l."

H.U.R.L. is a nonviolent video game aimed at children 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 FPSes that followed closely on the release of Doom and other games such as Wolfenstein 3D 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").
