Mattel's Catastrophe (19--, LED, 9 Volt, Model# 1671) (Never produced)
This game was never released as Catastrophe, but was later renamed to Gravity and released under that name. The game in the picture below (from a Toy Fair catalog) is a wooden mock-up to show how the game would look and was created during the early design stages of the game. The name/theme was possibly changed for the same reason Missile Attack was changed: The idea of a city full of people being destroyed if you lost the game was a little more violent than you wanted for your children.
Do I have this? No.
