How Halo 4 could pan out

I desided to come up this a story for what might happen in Halo 4 in a mission by mission plan.

Prologue (on the Dawn)

  • Cortana wakes up John as they approach the Planet (will refer to as Avalon, which will be like the shield world from Halo Wars).
  • You guide John through the burning Dawn avoiding explosions and the like while the ship enters Avalon.
  • Before the ship crashes on the inner surface of Avalon, you find a SOEIV drop pod and escape.

Mission 1 (Avalon surface, Day, similar to 2nd level of Halo CE)

  • You emerge from your pod and begin to look around.
  • Cortana copies herself and asks you to put it in a terminal so that she can have a poke in the systems.
  • The copy is quickly attacked by Mendicant Bias (He was already dormant inside Cortana since Halo2, plus a copy that was left on Avalon), taking over her and forming Bias-cortana (she is a red evil rampant Cortana).
  • Bias-cortana sends all kinds of sentinels to attack you.
  • You fight off the sentinels and make your way to the wreckage of the Dawn for safety and to collect supplies.

Mission 2 (Avalon surface, Night, Forerunner Complex)

  • Because of the link between Bias-cortana and the real Cortana, she has access to some systems. She finds out that the UNSC Infinity is looking for you and that if you activate a Portal Grid, it will allow the Infinity to jump to Avalon to rescue you.
    (Because of the link she shares, throughout the campaign, Cortana will have some breakdown moments, as she herself get closer to rampancy)
  • Using an undamaged power cell from the Dawn, Cortana jumps you to the pyramid Complex where you can activate the grid.
  • However, Bias-cortana has found a way to release the Flood specimens from study and the complex in now overrun with flood specimens and sentinels.
  • You fight your way to the access point which, because of the Infinity’s Forerunner parts, allows it to jump to Avalon
  • As the Infinity picks you up, hundreds of Forerunner ships also arrive and head for you.

Mission 3 (Onboard UNSC Infinity)

  • You are quickly greeted by Captain Serin Osman how has just enough time to give you your new armour and debrief you on the Covenant situation before Forerunner boarding craft attack the Infinity.
  • The Forerunner’s intentions aren’t clear but you are told to defend the ship and so you go about killing the boarding parties.
  • This mission would be like the PoA from CE, allowing you to get a good look around the UNSC Infinity.
  • Just when you think you are winning, the ship is overwhelmed and you, Osman and a few others are taken to the Forerunner capital ship.

Mission 4 (Onboard Forerunner ship, Atmosphere above surface)

  • Once onboard you are taken to the Didact to tells you that he is not pleased with all that humanity has done to forerunner constructs such as the Halo Wars shield world, Alpha Halo and the Ark.
  • He also tells you that by activating the Portal grid, the ancient enemy is able to return. It is only an amount of time before the figure it out. However, he is willing to put all that aside if you help him quell the Flood threat on Avalon and close down the Portal grid.
  • Bias-cortana has managed to gain control of many Forerunner ships and has forced the Flood upon them. You are given command of a Forerunner war sphinx to battle infected craft in atmosphere while the Didact and Osman return to their ships to fight the larger flood vessels.
  • As the mission comes to a close, the first wave of the ancient enemy pours in to Avalon. You quickly shut down the grid which disallows the enemy to leave Avalon and escape in to the rest of the Galaxy. A large Forerunner vessel is shot down and descends on the complex. You get back in the sphinx but take heavy damage from the explosion and you crash.

Mission 5 (Avalon surface, Night, forest/jungle)

  • You wake up in the middle of the burning jungle; the ancient enemy is laying waste to the Forerunner ships above. Cortana informs you that the Didact’s ship was destroyed he escaped and wants to rendezvous with you at a small Forerunner outpost.
  • Fending off against flood, sentinels and the ancient enemy, you make your way to the forerunner outpost through the burning jungle, allying with surviving forerunners along the way.
  • Once you reach the outpost, you, the surviving forerunners and the Didact must hold out your position fire fight style for Captain Osman to evacuate you.

Mission 6 (Avalon Control Centre)

  • Onboard the Infinity, you and the survivors try to decide what to do. Eventually a plan is formulated to re-open the Portal grid to bring a Halo Installation to Avalon to be fired on a low frequency to destroy Avalon and everything inside it. As the pyramid complex was destroyed, the only way to re-open the portal grid is to use the Avalon control centre. However this is where Bias-cortana is forming a Gravemind.
  • The first half of the mission has you fighting off the flood and sentinels, but the ancient enemy finds out your intentions and converges on your location.
  • Cortana is forced to make a truce with Bias-cortana; the flood will aid John and the Didact get to the control room, and in exchange, Bias-cortana be allowed to leave Avalon and travel to another galaxy with the Gravemind.
  • In the control room, the portal grid is opened to allow Installation 05 (Delta Halo) to pass through slipspace and inside Avalon.

Mission 7 (Delta Halo surface, Day, Snowy mountains)

  • Captain Osman informs you that the Delta Halo Index is in the custody of ONI, but all of the data has been stored on file. If she can get to the Control room, she can activate the Halo, but first you need to find it. (The Arbiter was the character who visited the Control room in Halo 2, so realistically the Chief would not know where it is).
  • So you and the Didact go in search of the Cartographer in war sphinxes, fighting the ancient enemy, and occasionally aided by the flood. Once you find and access the cartographer, you tell Infinity where to access the Control room and you rally with them there. (This is also a nice spot to see what the Halo 2 level uprising would look like with the updated graphics).
  • Cortana tells you that because she split herself at the beginning of the game, he rampancy in increasing and she needs to rejoin her copy in order to prolong her life, telling John that she will be strong enough to defeat Menecant Bias and take herself back.

Mission 8 (Upper atmosphere of Avalon)

  • Captain Osman has altered the Halo’s firing range and is set to remotely activate it once the Infinity has exited Avalon through the entrance you came through. You are given a forerunner enhanced Longsword to escort the Infinity from the Halo to the exit, fighting off ancient enemy ships.
  • The Didact regrets that his fellow forerunners are staying behind to try and distract the ancient enemy while you escape. The forerunner ship that is carrying the Gravemind is also with you.
  • As you are at the exit, you learn that the Gravemind has overpowered Bias-cortana and is escaping with the forerunner ship to infect our own galaxy, breaking the deal. They also realise that Bias-cortana is stranded back on Avalon.
  • You tell Osman to follow the Gravemind out of Avalon and try to destroy it, while you travel back to save Bias-cortana. Captain Osman gives you the firing controls in the hope that you will be able to make the right decision should you fail.

Mission 9 (Avalon surface, Night)

  • The Gravemind jumps in to slipspace and Infinity follows, leaving you behind.
  • You travel back to the surface to rescue Bias-cortana who is having bipolar episodes of attacking you, and then helping you. The main enemy in this level is the ancient enemy and the sentinels.
  • Once you reach Bias-cortana, Cortana separates herself from Mendicant Bias and you both escape. You activate Delta Halo and open the portal grid just long enough for you to get back in your Longsword and fly to the portal.
  • Delta Halo destroys Avalon and everything inside including the Halo itself.

Epilogue (Earth)

  • The Portal at earth opens and John and Cortana burst through.
  • They get debriefed at Sydney and there is a big cliff-hanger that leads in to Halo 5…
    DUN DUN DUN!

Nice plot idea there, but if I may, i’d like to point out a small flaw or two. Mendicant Bias is not exactly rampant. In the final Halo 3 terminal if i’m not mistaken, Mendicant Bias purposely sent you to the Forerunner Shield World(currently referred to as Sigma 7) to attone for his sins(turning rampant during the Forerunner-Flood War and joining the Flood in attacking the Forerunners and if it had not been for Offensive Bias, he may have succeded in destroying the Forerunners. But he didn’t, they trapped him and split him into fragments. As of Halo 2, Mendicant Bias was on the Forerunner Keyship that the Covenant posessed. He made it to The Ark in the ship thanks to Truth, and due to having considerable time to think about what he did to the Forerunners, decides that the only way to atone for what he had done was to send any human he could to Sigma 7.) I have a feeling that if there was a fragment of Mendicant Bias hidden in Cortana, it would not be hostile. As for the Didact, according to his Halo wiki page, he died in 100,000 BCE. However, since it is a military status, it is not entirely impossible that there would be a new one if the Forerunners still existed on that Shield World, though I highly doubt the position would be needed if they were living peacefully without chance of any grave threat. As for the Ancient Enemies, it seems likely that they are either Corrupt Machines and possibly a Rampant AI who controls them, or Precursors since it is not known if there are others beyond our galaxy. The msin enemy however, is likely to be The Timeless One who appears in Primordium and again, if i’m not mistaken, he is a Precursor. Good story idea though. Really creative, I like it.

I like your idea a lot

Thanks for pointing out some stuff.
I will admit that I have not read the Halo 3 terminals fully, although I thought that in Cryptum, Bornsteller practicaly becomes the Didact, and 343 Guilty Spark fortells his return in Terminal 10 of CEA.
So, I don’t know?

Bornstellar did become the new Didact. However, the Halo Array was activated 100,000 years ago, hence his death date of 100,000 BCE. If he activated a Halo ring, he was most likely killed, though Didact is pretty much a title and can be passed down as it was to Bornstellar.

Sorry for being an -Yoink-, but your idea is way too specific to remotely reflect what we will see in Halo 4. Writing out nice stories shouldn’t be misunderstood as theorizing, all it is is possibly spoiling what the devs planned on doing. I am sure its a good idea, but I don’t plan on reading it. :slight_smile:

Breaking News: I may have found evidence to support the theory that the Didact will most likely be in Halo 4. What have I found you may ask? If you have Halo: Combat Evolved Anniversary, and have found the 10th Terminal on The Maw, watch it. It gives a few hints. At the very end, the screen will start to flash and The Didacts symbol appears on the screen very briefly. I’ve seen this kind of thing before and its usually a hint at things to come. Not to mention in that very same Terminal, Guilty Spark talks about The Didact as if he is still alive. He also mentions that without The Librarian to temper The Didact’s rage, he is not too be messed with. So now i’m in bigger support of your plot idea considering it features the Didact heavily. I also support the Flood theory because 343 Guilty Spark references them as an Ancient Enemy. However, the Ancient Enemy of Halo 4 is supposed to be much older which means its either Ancient Humans who were known to be on par with the Forerunners, or the Precursors who are far older and the previous great civilization before the Forerunners. They were Tier-0 which is the highest your can possibly go. the Forerunners are Tier-1.

i dont want to read this because i dont want it to spoil halo 4 for me lol

i like it all but the end doesnt match up with the timeline. Halo 4 takes place in 2556. UNSC couldnt find MC 40 (may be wrong number, but im preety sure its way after 2556) years. just pointing that out there.

Believe isn’t canon.

Yah. Halo 4 has already been stated to take place in 2553. Though the Warthog is stated to have been made in 2554. Halo: Origins and other assorted things are no longer canon when talking about the Master Chief still being in space in 2556 and still not having been found decades later.

As long as he isnt gone for 10 years or longer,people would be dead and John alienated.
It should still be in the 2550s…it just seems the right route to take considering this talk about Halsey,the Spartans that were with her,and the Arbiter’s peace agreement with Earth.
