回到未来1

　　利用《电子战场2》留下的片段和一条非常细的故事线，亚历克斯再次与1998年在非洲东部的机器人雇佣兵作战。这一次，亚历克斯发现她有20个半姐妹正在等她回到2077年。中央司令部希望亚历克斯被活捉并扫描，看看她的DNA是否比正常的DNA更强更有力。但是亚历克斯可能太苛刻了，不值得去捕捉。

　　While driving through the desert with his wife Carol Marvin to a military base to send the eleventh rocket to the orbit of Earth for helping the exploration of the outer space in the Operation Sky Hook, Dr. Russell A. Marvin and Carol see a flying saucer and accidentally records a message in their tape recorder. Once in the base, Dr. Russell is informed by his father-in-law and general that the ten first satellites had mysteriously felt on Earth. When Dr. Russell decodes the message, he encounters the aliens that ask him to schedule a meeting with the leaders of Earth in Washington in 56 days with the intention to invade Earth without panicking the population. Dr. Russell develops an anti-magnetic weapon that becomes that last hope of human race against the hostile aliens.
