I know it’s too early for a new campaign DLC but they are so many question about what happened before Master Chief wake up, so I imagined this story with Osiris who take care of the weapon
Mission 1 : During the boarding of the banisheds, Osiris recover “the weapon” and escape the Infinity with it
Mission 2 : Osiris land on Halo to insert “the weapon” in the Halo system and the Guardian send the prometheans to stop them.
Mission 3 : Osiris insert the weapon in Halo and defend her against the Banished and the Prometheans until the uploading is complete. Locke sacrifice himself against a brute chieftain and the rest of Osiris is forced to evade. (When they see the Guardian fall and the prometheans disappear, they understand the weapon neutralize Cortana, but they have no way to confirm she erase herself)
Mission 4 : Buck command Osiris team to hunt down the brute chieftain who kill Locke. They board his drednaught ship and kill him. The ship crash somewhere in Halo. (meanwhile, the 2 brutes Tovarus & Hyperius survived the crash and Hyperius recovers Locke’s helmet to hang it on his armor)
Mission 5 : Six mounth later, Osiris discover Atriox and Master Chief are alive. They attack Atriox base and recover intel on the Endless.
End : They contact the Master Chief
I chose to start this story in the Infinity because I find important to live the defeat of the biggest UNSC ship by ourself (rather than in a small cinematic !)
I know Prometheans aren’t popular, so I made them appear only in two missions (they are the principal soldiers of Cortana and the Created so it’s important they appear somewhere)
As the weapon itinerary is difficult to establish with the info we have, I presume she can be upload anywhere in the Halo for her mission. She said in the campaign she went in the silent auditorium to neutralize Cortana, but she didn’t precise if she was physically upload there or if she deplaced herself in the informatic system.
We can see in the campaign that the boss Hyperius wear the helmet’s Locke. I choosed an other brute to kill Locke (the chief brute who I don’t give a name) because Hyperius was a little boss in the campaign and I find Locke deserved a better death.
I finished this story by a connection with Chief, Atriox and the Endless to continue the main story.
What do you think ?
