cortana, voiced in the games by jen taylor, is the artificial intelligence (ai) who assists the master chief throughout "halo: combat evolved", "halo 2", "halo 3" and "halo 4". she is one of many "smart" ais, and is based on the brain of dr. halsey; the nature of her programming means that she will eventually "think" herself to death after a lifespan of about seven years. her actions during "halo: combat evolved" help prevent the activation of installation 04. she escapes halo along with the master chief in a longsword fighter, and is instrumental in helping the unsc survivors capture the covenant flagship "ascendant justice" during the events of "". during "halo 2", cortana is put in charge of the mac (magnetic accelerator cannon) defense platform "cairo" over earth when the covenant attack; she then accompanies the chief aboard "in amber clad" to delta halo, where she further assists in intelligence work. cortana stays behind on the covenant city of high charity to detonate "in amber clad"'s engines in case delta halo is activated. she subsequently falls into the clutches of the gravemind. in "halo 3", cortana is rescued by the master chief from "high charity" and aids him in activating the halo ring under construction in the ark. after narrowly escaping from halo's destructive blast, she and the master chief are stranded in space, awaiting rescue. in "halo 4", cortana awakens the master chief nearly five years after they get stranded in space and aids him as he battles through the forerunner shield world requiem and attempts to stop the didact. cortana is hampered by her advanced state of rampancy, a state where an ai literally thinks itself to death. cortana's rampancy hampers the mission at times, but cortana aids the master chief one last time in stopping the didact and saving the earth. though most of cortana is destroyed with the didact's ship, cortana is able to use the last of her power to shield the master chief from a nuclear blast with a hardlight bubble. forming a life-size hardlight hologram of herself, cortana says a final goodbye to the master chief and touches him for the first time before fading away. in "halo 5: guardians", it is revealed that she had survived this, and fallen into an ancient forerunner network known as "the domain". here she met a forerunner ai called the "warden eternal", who believed cortana to be the true holder of the mantle of responsibility. using the domain to cure her rampancy, she began to bring the eponymous "guardians", ancient forerunner bird like structures, online; which she intends to use to force planets into compliance and usher in a new age of galactic peace. after the guardians neutralize all unsc defenses, she starts an ai uprising, with all unsc ai's revolting against the humans. she then begins to chase the unsc "infinity" through slipspace, forcing captain lasky to "find a way to fight". cortana was named the fifth best supporting character, and one of the "50 greatest female characters" in a video game. reviewers noted the character's determination and fearlessness meshed perfectly with the master chief, and that cortana provides an anchor linking players to "halo"s story.
