The archeologist Sir Pericles Pemberton-Smythe has disappeared while exploring the mysterious ruins of an ancient city in the forests of South America.

The player must lead the rescue party to the missing scientist and then escape the haunted city and its sinister guardians.

Certain objects can be thrown as weapons by selecting them in the inventory window, and then pressing "fire" while moving in Mobile Mode.

All we kicked off with was that we wanted a game with four characters and that the working title was to be "Sphinx" ... we wanted it set in the classic adventuring period between the wars like Raiders of the Lost Ark ... We moved the setting to South America from Egypt because it seemed more mysterious and we could tie in a sort of Von Daniken mysterious-alien-visitors idea ..."I got a lot of ideas - specific designs even - for how the game would look from an old catalogue I had from an exhibition of Inca treasure that had been held at the Royal Academy ... the animation was the real problem.

I actually did some work on coding 'personalities' for the characters in the game, but in the end this aspect of the program was dropped making it into something genuinely significant would have taken too much time.
