The Siberian Cipher

The Siberian Cipher is a cancelled PC game by Sanctuary Woods. It was to be a sequel to The Riddle of Master Lu.

Plot
Robert Ripley would pursue a group that has found the remains of the Tunguska meteor. There was also other meteor sites of interest, like those in Africa and Australia. The game would start from the Bodleian Library at Oxford University and Ripley Museum in New York.

At one point you would travel to Geneva and break into a Swiss bank. At another point Ripley would be locked in a trunk and thrown into Lake Geneva. You would also travel to China to tie up loose ends from the previous game.

Cancellation
The Siberian Cipher was cancelled due to Sanctuary Woods being bought by Disney. The game never left pre-production. In 2004 there was discussion of this game resuming production but it never happened.
