I found Cortana in a giant hidden, foggy black box in Halo 3
To date, this is the easiest method to find and interact with Cortana's player model in all of Halo 3. The mission is on Floodgate and you'll only need 2 players and the Acrophobia Skull to get it done. This can be completed on the Master Chief Collection on both Xbox and PC.
