Curse: The Eye of Isis

Strange things are happening at Great Britain’s museum of natural history in 1890. A gang of ruthless thugs has broken into the establishment, the Eye of Isis Egyptian statue has been stolen, and a mysterious fog has overtaken a number of areas of the museum killing and transforming all it comes into contact with. In this survival horror game you will be playing as museum curator/archeologist Victoria Sutton and her childhood friend Darien Dane, you’ll have to fight the various beings and entities created by this fog. You'll spend considerable time in the museum, take a steam train to the coast and travel the seas in a huge cargo ship before finally entering the pyramid tomb where you must find and destroy the source of this ancient evil.
