According to Commodore Format Issue 35, Test Master 2 was a game by E&J Software that was currently on sale and selling well at number 7 in the charts.
However, what happened to it? CF never reviewed it and it has yet to surface anywhere. Surely if it was at number 7, then it would have sold a few copies!
It is possible that CF had cocked up some how and had meant it for their news section – but no corrections were ever made. The original game was released back in 1990 by Challenge Software.
Do you know more about the game? … did it actually get released?
