Any Halo 5 story ideas?

My idea is that the UNSC finds another Halo and send down the Spartan 4's with the Chief. The Flood are still on it as test subjects and get released by the monitor of the installation to get rid of the UNSC. They infect one of the ships in the fleet and jump into slip-space. The Infinity pursues them. They end up the second Ark where there are some remaining Forerunners in stasis. They get revived by the storm covenant which are in the middle of a three way battle with the runaway flood ship and the Arbiter's fleet. The Infinity aids the Arbiter's fleet in pushing back the storm covenant and the Flood ship crash lands on the Arbiter's ship. The Chief and a squad of Spartan's get sent over and find out that the Bornstellar Didact is suppressing the flood and the elites. A Halo comes out of the second Ark and starts to fire.

ONI sends the Master Chief to kill Halsey, who has teamed up with Jul 'Mdama to get revenge on Palmer and the UNSC. The Arbiter is struggling to keep the Storm Covenant from taking Sanghelios. On a Forerunner installation manned by Prometheans guarding a sample Flood matter, the Chief finds out that Halsey knows how to retrieve Cortana from a site linked to the Librarian's key. He must choose from following orders--killing Halsey--or bringing back Cortana. Jul 'Mdama moves his fleet to take Sanghelios for the Storm, but his advance is stopped by Infinity, which--with the help of Forerunner technology found on Requiem--transports Master Chief onto the ship holding Halsey. She proposes a deal: let her escape, and she will bring back Cortana; if not, she will release the Flood from the installation. Chief chooses the first option, but the Cortana that Halsey brought back isn't the same--it downloads an advanced virus onto Infinity, crippling the ship. Halsey then goes to transport to Archive--a special place on the installation that contains all the knowledge of the Forerunners--but Chief gets pulled along with her. On the other end, Bornstellar Didact is waiting with an army of Promethean Warriors. In a desperate attempt to survive being destroyed completely, Halsey unleashes the Flood, knowing that it will unify her knowledge in the Gravemind. Arbiter, still on Sangehelios, manages to turn the Storm Covenant against Jul 'Mdama. Unfortunatey, Infinity is caught in the crossfire and is forced to abandon ship and jettison dozens of fireteams to the war-stricken surface of Sanghelios where the Prometheans await. Further chaos ensues...

 

There might be a couple of errors in here, but I think it's a pretty solid starting point.
