So I was contemplating the Halo Timeline and how much Halo 4 and 5 sucked compared to the previous games, when I had this theory come into my head like a lightbulb. Halo 3 ends with Master chief in space. No more covenant no more flood. In Infinite Master chief is found in space rubble and was evidently attacked by the Banished in a ship of some kind. My theory is that the ship he was attacked in was the Forward Unto Dawn after UNSC found him, but was intercepted by Banished forces. My Theory is that 343i might actually make Halo 4 and 5 non-canon. Now Halo 4 and 5 were poorly written and experienced extreme backlash from fans and average gamers. Let’s be honest, those games pale in comparison to Halo 3. Another factor that supports my theory is Master Chief’s “new” armor, it’s the same armor as Halo 3. I believe that is a sign because 343i wants to remake the glory of the old Halo games. And I’m doing so, they cut out the created and promethean forces from any trailers or media related posts on Halo Infinite. 343i might be creating a favorable timeline for fans to enjoy. A few other factors are where Chief is in the beginning. Floating aimlessly in space, just like In the end of Halo 3. Just a quick fact in all of the reclaimer saga previous, we never set foot on a halo ring. Now we are practically living on one in Halo infinite.
thanks for reading. This is just a theory and a very unsubstantiated one at that. Put in the comments what you think!
