I'm looking for the name of a game from about 15yrs ago. It involved 2 cannons trying to shoot eachother?

It was a long time ago. My grandparents had it. Back when Floppy Discs were the big thing. It was just two cannons, I think a red and a blue one, trying to kill the other.. anyone know what this was?? Back when there was a similar low graphics version of Wheel of Fortune...
