Perfect Dark N64 Game

Players take on the role of Joanna Dark (codenamed "Perfect Dark"), a talented rookie agent at the Carrington Institute, a private research institution dedicated to peace and technological development. 

The core conflict of the story begins with Carrington Institute's competitor, dataDyne. DataDyne is a large enterprise that appears to be engaged in defense technology, but is actually ambitious and unscrupulous. The leader of dataDyne, Cassandra de Vries, and his trusted assistant, Dr. Carroll, are secretly collaborating with an alien race called Skedar. 

Skedar is a warlike alien race of lizard people who attempt to use dataDyne's technology to establish a clone production facility on Earth, in order to provide a continuous supply of soldiers for their war to conquer the universe. In exchange, dataDyne will receive Skedar's advanced extraterrestrial technology. 

Joanna Dark's mission is to expose and thwart the conspiracy between dataDyne and Skedar. Her first mission was to obtain criminal evidence of dataDyne for the Carrington Institute, but she soon became embroiled in a complex event involving extraterrestrial technology, corporate conspiracies, and global threats. 

As the plot progresses, Joanna needs to shuttle around the world (such as Chicago, Area 51, etc.) and Skedar's alien spacecraft to fight against dataDyne's mercenaries and Skedar aliens, ultimately preventing Skedar's plan to invade Earth.
