There were no none plus release of this title, nor it would seem a specific release without the plus logo on the UK variant, we simply got the + cover, as far as I can tell. Neither was their a US release for the Magnavox. The Brazil variant does not have the enhanced plus graphics, although the European version, regardless of market does, although since no plus consoles were released in the UK we would never have benefited from those background effects. Point of note, is I'm not certain that any more titles were released in the UK for the Videopac, beyond 53 Nightmare, quite literally. if anyone has any evidence of this arriving naturally in the UK in the early 80s, or any marketing please let me know.
