Saw a thread about this a few years back. Led nowhere. One user claimed to have a cousin who worked on the series. Might've been a dead-end but could be worth looking through old posts?

Talk about a shot in the dark! Can you remember anything else? The gameplay mechanic, any unique enemies or items, stuff like that? It could be Indiana Jones and The Last Crusade: The Graphic Adventure. Or not. I need more details, mate. :D
