Chex Quest

Chex Quest is a promotional game created by and released in, utilizing the Doom engine. The player is embodied as Chex Warrior, a hero attempting to rescue captured Chex people from evil slime creatures known as Flemoids who have invaded the Intergalactic Federation of Cereals' mining outpost on the planet Bazoik. The game was made available inside boxes of cereal. It 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 are instead transported back to their home dimension.

The game is notable for the fact that it was the first game to be released inside a cereal box. Sales of Chex cereal jumped by over 200% during this promotion. Much of the manufacturing cost of the CDs was paid for by. AOL was allowed to include its dial-up online service client on the disc in exchange for this contribution.

Story
Chex Quest begins with an emergency meeting of the members of the Intergalactic Federation of Cereals. In it, it is brought to everyone's attention that a volcano exploded recently on the surface of Bazoik, a peaceful mining planet renowned for its quality nutritional products. The Chex Squadron captured fragments from the explosion, and discovered that they contained strange, slimy larvae of a creature from another dimension. When exposed to nutritional substances, these larvae abruptly grow into huge, slimy creatures with the capacity to launch slime as a weapon from their bodies. Even more disturbing, communications with Bazoik have been interrupted, and the Federation cannot contact anyone.

Luckily, the scientists from the Federation have found a way to counter the threat. Although conventional weapons do not affect the slimy invaders, the scientists have modified the "zorchers", the main weapon of the Federation, to effect a transportation of any object into another dimension.

With this new weapon, the Federation believes that it can subdue the threat by sending a lone volunteer to the surface of Bazoik. The crowd discusses this for a moment, and the Chex Warrior declares he is willing to take the rescue mission. Taking his ship, he flies to the planet and begins his quest.

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 largely the same as in the first Chex Quest game, though some enemies have been changed cosmetically. Game development on the sequel was rushed to completion, with a lot of graphics being reused from the first game and the levels lacking in detail and quality.

 * E1M5: Sewer System

Chex Quest 3
The original Chex Quest 3 was made by fans of the series who were disappointed that the third had been canceled. But, rather than make entirely new levels and graphics, most of them were taken from other mods, including Hacx and STRAIN. This PWAD was noticeably more difficult. It was largely disregarded by the community when its unofficial status was confirmed. Team Eternity later started work on a different Chex Quest 3 project, but abandoned it.

Ten years later, Charles Jacobi, a former member of Digital Café, created and released his own Chex Quest 3. In addition to an all-new five map episode, the first two games were given a makeover and included as well.
