Heck, Master Chief might be a wizard with every kind of weapon and gun around, but he’s useless when it comes to hacking computer systems. That’s where Cortana comes in! She’s great at that, but she’s also pretty darn good at mission planning, reading Covenant data and controlling space ships. Now just compare that to what Master Chief does during the course of the Halo games. All he is good at is jumping around and shooting guns… so it’s safe to say she’s a pretty important portion of any operation to save mankind.Perhaps you’re looking to save mankind from destruction, just like Cortana from Halo?
