The Gene Machine

The Gene Machine is a point-and-click action adventure game. It describes the adventures of a fictional British gentleman named Piers Featherstonehaugh and his manservant Mossop. The plot shared many common elements with Jules Verne's Around the World in Eighty Days, Twenty Thousand Leagues Under the Sea and From the Earth to the Moon, as well as many other literary and historical references to Victorian England, such as Sherlock Holmes, Treasure Island, Jekyll, and many others.
