Hi Guys, I have this old game from the 80s. It's by Atari and U.S. Gold (not really from the U.S, the company comes from Britain). It comes on a 5 1/4 inch floppy disk. Doesn't explicitly state what system it's for, but I'm guessing the Commodore 64. But honestly, I don't know. There's a mention of a "SYSTEM RESET" key, if that counts as a clue.
Little Google Search shows it is indeed for the Commodore 64, as well as some other ones. Search ''Beach head platforms'' to see the other platforms.
