Halo 3 - Legendary Walkthrough - Mission #8: Cortana

Game: Halo 3
Mission: Cortana
Difficulty: Legendary
Skulls: Iron, Cowbell, IWHBYD, Grunt Birthday Party

Hello everyone and welcome to my Halo 3 Legendary Walkthrough Guide. After successfully stopping (and killing) the Prophet of Truth and activating the Halo Array, we discover a replacement to Installation 04 (the Ring you destroyed in the first game). With a new Halo, we will use it to activate it to extinguish the Flood along with the Gravemind on the Ark. However, in order to activate it we need the Index in order to fire the Halo. Your job is to venture into Flood-infested High Charity, retrieve Cortana, and destroy High Charity. If you liked this video, please consider liking, subscribing, sharing, and/or commenting below!
