Chex Quest is a non-violent first-person shooter video game created in 1996 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 the Golden EFFIE Award for Advertising Effectiveness in 1996 and the 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. Gameplay Originally based on the Doom engine, the gameplay present in Chex Quest is substantially identical to its predecessor. The game is played in a first person perspective with the player character navigating through quasi-3D environments while enemies attempt to attack and immobilize him. Along the way, various cereal-themed power-ups, weapons, and ammunition can be found that can boost the player character's health and make him better able to counterattack or flee his enemies. When the final boss is defeated in the last level, the game is won. A few notable differences from Doom are evident, however, regarding enemy profiles (specifically the loss of long-range attacks in low-level enemies and the loss of movement in high-level enemies) and the number of levels in each world (restricted to 5 levels in Chex Quest). Plot Set on a distant planet named Bazoik, the game follows the Chex Warrior, a soldier clad in a Chex-shaped suit of armor, as he foils the invasion of the planet by the 'Flemoids': a species of slimy, green invertebrates, who have infested the planet and captured many helpless colonists, whom the Chex Warrior must save. His main weapons are devices called "zorchers", which teleports his enemies to their home dimension. The game starts at the landing pad of the research center on Bazoik; other levels include the laboratory, the arboretum, and finally, the caverns of Bazoik, where the Flemoids have established their colony. Their principal weapon is the use of mucus as a projectile. Development Produced with a small team of developers on a budget of around $500,000,
