*spoilers* How Halo Rings go *Spoilers*

The Cheifs Brother

Well in Halo 1

The Halo Ring is destroyed and falls into space not to be seen again(Bye Blood Gulch:()

In Halo 2

The Flood starts infesting the Halo Ring and the Marines(Plus Master Chief) are forced to retreat and the Flood Destroy Halo

In Halo 3.....

Cortana has been captured and the chief needs to get her back to finish the fight....

The Chief has to get to Halo's Control Room and Make Halo fire and shatters itself to pieces and the Covenant , The flood , The Truth are destroyed for good

But if you finish Halo 3 on Legendary with all achivements you will see the Chief and Cortana land on Venus after the Credits end

So could a new fight start?

Could the Covenant , Flood , and the Truth be back
And could Halo be remade once again?

Only Bungie knows

Here is the vid of Cortana and chief landing on Venus
