Chex Quest

Chex Quest was a game based on Ultimate Doom where 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 the late 1990s. 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, instead they are transported back to their alternate dimension.
