You are Ronald McDonald flying in your spaceship. Hungry aliens are descending on the Golden Arches below to eat them.
You must fly down to the ground and pick up McDonald's food to bring up and feed the aliens, but certain aliens will only eat certain McDonald's fast food (shakes, fries, hamburgers) so you need to feed them the right food. If you don't feed them in time, they start to eat the Golden Arches, but not to worry, you can fly back down to the ground and pick up pieces to rebuild the Golden Arches.
A roughly finished version of the game was taken to a focus group and they were shown the game. Unfortunately, out of the focus group only children between 8-9 years old had both an interest in McDonald's and in playing the video game. So due to the extremely restricted target audience, management immediately canceled the project. While Isabel retained 2 copies of the very early game code, she says it is possible that a more complete version of the game exists. She said an Atari 400/800 version had been started as well during the 2600 game development, but is not certain how far that particular version progressed.
