Chex Quest is a child-friendly non-violent first-person shooter video game, created by Digital Café. It is a total conversion of the more violent video game Doom (with easier levels and modified graphics & sound). Chex Quest, notable for being the first video game ever to be included in cereal boxes as a prize, was found in boxes of Chex cereal in 1996.
In addition to the original game, Digital Café later made a sequel to Chex Quest called Chex Quest 2, which was only available for download on the Internet. Eventually the promotion ended and the game's availability effectively stalled until it was posted for download on fan pages several years later. In September 2008, a second sequel, Chex Quest 3, was developed and released as a service to fans by former Digital Café members Charles Jacobi (art director and lead artist) and Scott Holman (programmer).
