Chex Quest is an action game (FPS) released in 1996 by Ralston-Purina. The game was released for PC (DOS).
Chex Quest is a game that uses the engine from DOOM Engine. As in DOOM, the action was presented from the first person view.
You play as a "waffle" man whose task is to get rid of all Flemoids from the planet Bazoik. Flemoids are creatures similar to green mucus that steal food collected on the planet.
Just like in other games like this, you'll be going through hundreds of mazes and your weapons will be bootspoon and Zorcher.
