WizardWorks is a defunct video game company based in Minneapolis, Minnesota. The company was founded in 1980 and, in 1993, WizardWorks opened the CompuWorks and MacSoft divisions. In 1996, WizardWorks was acquired by GT Interactive to become part of their GT Value Products umbrella, which was later abandoned. It has published various games, as well as unofficial fan-made level compilations for Doom, Doom II, Heretic, Hexen, Duke Nukem 3D and Quake. The company was eventually bought and disassembled by Atari.
WizardWorks has often been criticized for creating products of questionable quality. They have also been accused of violating the Doom EULA by selling Doom modifications without id Software's permission.
