Chex Quest was a game based on The Ultimate Doom wherein the player is embodied as a Chex Man attempting to rescue captured Chex people from evil slime creatures. It was available in boxes of Chex cereal in 1996. The game featured five levels. Because the market for the cereal consisted largely of children, the game was made to be deliberately non-violent: for example, the enemies in the game are not killed, but instead transported back to their alternate dimension.
The game is notable for the fact that it was the first game CD ever to be released via a cereal box. Sales of Chex cereal jumped by over 200% during this promotion.
The game was created by Digital Café.
Much of the manufacturing costs for the CDs was paid for by America Online. AOL was allowed to include its own online software in exchange for its contribution.
Chex Quest 2
Chex Quest 2 is the second installment in the Chex Quest series. It is an add-on to the original, as the first Chex Quest is required to play it.
Chex Quest 2 was available only from the official website, and only for a limited time. The basic gameplay and backstory are the same as the first Chex Quest game.
Chex Quest 3
Chex Quest 3 is a beta version of the last entry in a series of Doom-style promotional games included inside selected Chex breakfast cereal boxes. It has the same backstory and basic gameplay of the earlier Chex Quest games.
Being a beta version, Chex Quest 3 was never officially released in boxes, although the developer put up the game for free download on their website (now defunct), along with a blurb about an upcoming Chex Quest 4 that was never finished. The game is complete, though, and no obvious bugs are apparent.
In addition to the same wacky gameplay from the first two games, Chex Quest 3 includes new weapons, such as a clone of the super shotgun from Doom II, and several new monsters. Overall, it is very similar to Chex Quest and Chex Quest 2.
