Apple IIe Game

When I was a kid I remember playing a game on an Apple IIe computer where there were two small castles on each side. Each player had to enter cordinates and try and send a bomb to blow your opponents castle up. After you would launch a missile it would show a line so you knew how close you were. Does anyone remember this game? If so, do you know where I can get it. I tried looking online but its tough without a name. Thanks.

I never played that game, but I know that it wasn't just made for the Apple IIe.

Try looking for something like "Castle Defender" or something like that.
