Chex Quest is a non-violent first-person shooter video game created in 1996 and released in 1997 by Digital Café, originally intended as a Chex cereal promotion aimed at children aged 6–9 and up. It is a total conversion of the more explicitly violent video game Doom (specifically The Ultimate Doom version of the game). Chex Quest won both a Golden EFFIE Award for Advertising Effectiveness and Golden Reggie Award for Promotional Achievement in 1998, and it is known today for having been the first video game ever to be included in cereal boxes as a prize. The game's cult following has been described by the press as being composed of unusually devoted fans of an advertising vehicle from a bygone age.
In 2019, General Mills rereleased Chex Quest and its previously unofficial 2008 sequel, and presented a mini-documentary on YouTube.
