Who Is Cortana? The 'Halo' Artificial Intelligence Explained

Cortana (Jen Taylor) is one of the first characters that comes to mind when you think of the Halo universe. With a live-action Halo series on the way on Paramount, we thought a guide to Cortana (without giving too much away for those who haven't made their way through all the games) was in order. Cortana serves as a guide and ally to the player throughout Halo gameplay, and in that sense and many others, she is essential to the Halo experience. Her mannerisms as an AI make for a sort of dry humor that makes her stand out among other recurring characters in the game. It will be interesting to see how this character, who fits so easily into the video game format, will be adapted to a live-action television series.
