Halo 3 Series 1 - Cortana
Halo follows the events of an inter-galactic war between the last surviving members of the human race and an advanced collection of alien races known as The Covenant. The first title in the series, Halo: Combat Evolved, was the flagship title for Microsoft's Xbox video game console when it was released in 2001. The game achieved both critical acclaim and financial success, selling more than 6 million copies worldwide. Developed by the United Nations Space Command (UNSC), Cortana is a smart A.I. with the ability to project herself as a holographic image and be transferred between computer systems, including the cybernetic armor of Master Chief.
