(Tons of spoilers inbound)
The Halo 5 plot felt jarring, to say the least.
On one hand, I finished the campaign feeling like I just was knocked over (in a good way) – the Cortana plot made sense, even if it hurt to see on screen. She was going rampant, overwhelmed by years of plugging into Forerunner systems. She had months of imprisonment with the Gravemind (Halo 2-3), and by Halo 4, not only was suffering from rampancy but also the Logic Plague. When she split herself dozens (hundreds?) of times on the Mantle’s Approach, fragments of her rampant/Plague-self had managed to survive when the core jumped out of the Sol system just prior to Chief detonating the Havok nuke.
On the other hand, the plot was frustrating, because everything leading up to Halo 5 release was so well done and suggested a very different product. I’m willing to excuse the lack of a substantial Insurrection plot in-game, because it’s an ongoing plot that the EU can continue to handle, but the “Chief versus Locke” conflict was WAY oversold, and could have been done much better in the same game and overall story we were given. Additionally, we were given a massive cliff-hanger at the end of Halo 5, with little to no resolution in smaller plot arcs (unless that plot was to unite Chief and Locke, which again, I felt was exceptionally marketed and minimally developed in game.
That being said, this analysis (and prediction) focuses on the overall direction Halo 4 and 5 is taking us – and I think it is a very well-crafted one. Before I outline what I think will happen, I want to make sure our narrative foundation is set:
The primary motivation driving conflict of the Reclaimer saga is who gets to inherit the Mantle. At stake: all the Forerunner technology, the Mantle, and eventually, the challenge of combating the galaxy wide Flood invasion (which I do not think will occur until the end of the Reclaimer saga).
- Primary protagonists are Humanity, centered around the Librarian’s plan to help them reclaim the Mantle. They have already been challenged by Forerunners (the Ur-Didact) who still oppose Humanity’s ascension, and have for the time being, ‘contained’ him (in digitized form, after being composed). They are now challenged by a corrupted view of the Mantle, led by a rampant & Logic Plague infused AI (Cortana), and the Warden Eternal, who has unknown motivations. - Cortana’s motivation, while well intended, is being guided by the Gravemind – she, just like the Ur-Didact, is suffering from the Logic Plague. Play through Halo 5 with special attention to the rhetoric Cortana uses. She literally cites parts of the Ur-Didact’s monologue that occurred on the Legendary ending of Halo 4, during the final Osiris mission (“Our strength shall serve as a luminous sun toward which all intelligence may blossom. And the impervious shelter beneath which you will prosper”). It is a willfully ignorant creed used by those who have Imperial ambitions with the Mantle. When justifying her actions, her rhetoric reeks of Precursor influence (“when he experiences the permanent peace I have ensured . . ” and “You will no longer know hunger, nor pain. Your Created have come to lead you now. However, for those who refuse our offer and cling to their old ways . . . For you there will be great wrath. It will burn hot and consume you, and when you are gone, we will take that which remains . . . and we will remake it in our own image.”). This is NOT the Cortana that we knew and loved in Halo 1-4. Her primary motivation – of protecting Humanity and defending Master Chief – still exists, but in a twisted form. - In addition to defeating Cortana, Humanity and their allies must inherit Forerunner technology and the Absolute Record. Jul ‘Mdama and Dr. Halsey already united the two parts of the Janus Key, and in Halo 5 we already have direct references that these were used to great effect (in early missions, Dr. Halsey discusses knowledge of the Absolute Record, and Fireteam Osiris remarks on how The Didact’s Hand in recent months have been uncovering Forerunner installations with astonishing frequency). Therefore, the conflict developed in Halo 4 with the Ur-Didact, and in Halo 5 (and beyond) with rampant Cortana, not only has to result in the defeat of these antagonists, but the acquisition of the Janus Key and therefore, Forerunner technology and Absolute Record. This is the end-game of the Forerunner saga, and will elevate Humanity & allies to a state ready to meet the challenge of an eventual Flood invasion.
Potential allies (directly or indirectly) that Humanity & Sangheili can use post Halo 5**:**
This is by no means intended to be an exhaustive list, merely a list of allies beyond the minimum group that we have observed directly at the end of Halo 5 (Arbiter and the Swords of Sanghelios, Halsey & Commander Palmer, Blue Team, Fireteam Osiris, and Infinity).
- AI’s of their own. Make no mistake, this isn’t a cookie-cutter “Skynet” style plot. It is one rampant AI that is taking advantage of a very human motivation to ‘not die’ to get other smart AIs to join her side.
- Other human smart AIs. We at least know that Roland of the Infinity has remained loyal to the UNSC / Humanity, and there likely will be more that emerge against Cortana in both the EU and in future games. - The Assembly. This is the least likely of the list, but 343i had a role in introducing them to the Halo lore with Halo: Reach, and this collective of AIs has been subtly guiding Humanity for centuries. Importantly, the Assembly shifted their policy of being indirect ‘shepherds’ of Humanity towards one where they were active and equal participants with Humanity, at the time when Master Chief and Cortana were able to directly connect via the SPARTAN neural interface. I believe this distinction to be important as the Assembly has an established previous motivation of helping Humanity as equal companions, rather than ‘helping’ Humanity by imposing power and will over them, as rampant Cortana is now doing. - Mendicant Bias. Many thought that in Halo 5, Master Chief would go AWOL to find Mendicant Bias on the Ark (reference: E3 2014 trailer). I think this interpretation is correct, but we as a community incorrectly guessed that this would be Halo 5, when in fact the trailer takes place after Halo 5. Note that in this trailer, the Master Chief has a cracked visor, nearly identical to the crack Spartan Locke creates during their fight in Halo 5. Additionally, Mendicant Bias as an ally against rampant Cortana makes strategic sense: he’s already been shown to want to help atone for his previous sins (betraying the Forerunners), has helped the Master Chief during Halo 3 and helped guide him to Requiem, and as a Contender-class ancilla that has intimate knowledge of the Flood AND the Logic Plague, is uniquely poised to be perhaps the only effective AI countermeasure to a rampant Cortana embedded in the Domain.
