X is for Expert.
This is not some attempt to grift the Challenge. The Expert Set adventures were given the code X.
Of course, the most famous of these is X1, The Isle of Dread.
I got this adventure along with my Expert set back in the early 80s. It is an obvious King Kong homage, but it is a great one. It is another one of those adventures that people keep coming back to time and time
