Chex Quest HD is a re-release of the classic arcade shooter with a first-person view, where you have to fight off the invasion of evil aliens. An outpost of the Intergalactic Snack Federation, which is located on the distant planet Bazoik, has been captured by evil creatures from another dimension that feed on cereals. The slimy Phlemoids have captured the inhabitants of Bazoik, and you, as part of the Chex Mix squadron, must free them. Luckily, you have a breakthrough set of devices that will help you send the invaders back to their home dimension and successfully complete their mission.
