Probably my most favorite thing in Halo 3 are the little sequences in which either Cortana or Gravemind talk to Chief. The reason being is because when I got Halo 3, I had no idea what was going on, who was who, etc. So these little sequences made me curious about the storyline of Halo. And now here I am, 3 years later, and I know a vast majority of the Halo universe.
The mission “Cortana” in Halo 3 is my favorite out of all the Halo missions because it had such an impact on me when I first played it! I remember hearing Gravemind talk to me, pulling back the camera and releasing his powerful voice. And to tell you the truth, he scared the living shit out of me lol.
This video is a compilation of all the encounters with Cortana and Gravemind, and these sequences essentially are what got me into Halo.
