EVA

EVA appears in the game Metal Gear Solid 3: Snake Eater. EVA was born in Meridian, Idaho on May 15th 1936. She claimed to be the KGB agent sent to assist Naked Snake in Operation Snake Eater. She also claimed to be one of the NSA codebreakers whom defected in September 1960 along with ADAM, another NSA code-breaker. EVA uses her charm and good looks to win-over the trust of Snake as she double-crosses Colonel Volgin, Ocelot, and The Boss to help him reach Sokolov and the Shagohod.

It is revealed in her final monologue that EVA was actually an agent of the Chinese Philosophers and that her mission was to retrieve The Philosophers Legacy and kill anyone who she came across. As she watches Snake sleep on the cabin floor, she made the distinct decision not to kill him, because she had promised The Boss not to.

Snake then returned the microfilm containing the Philosopher's Legacy's whereabouts. The microfilm EVA had was given to her by The Boss during the Volgin boss battle, and was fake. Thus the American branch of The Philosophers (later The Patriots) was able to obtain the portion of the Legacy that China wanted. However, the American Philosophers were unable to obtain all of the Legacy, 50% still belonged to the Russians. However, in 1970, they were able to obtain the complete 100% of the Legacy.

EVA disappeared in Hanoi during the Vietnam War in 1968.
