If you didn’t finish halo wars 2 yet and good luck doing that don’t read this forum.

Really finish Halo wars 2 I don’t want spoil it…

Alright in Halo was 2 ending we see the new halo Tele transported to an unknown location which of course is Cortana’s plan and we also see a Guardian which yep it’s Cortana’s. my theory which is kinda obvious is that Cortana will use this halo to blow up our galaxy and probably the flood will be back. What do you think was halo wars 2 ending meaning? Are you excited to halo 6?

One why does Cortana need this one Halo ring? There are 5-6 more of that she can locate.
2. Anders neutralized it’s life killing part of the halo weapon.
3. Why would MS let 343 end their cash cow?
4. If the galaxy is blown up of all sentient life with the halo rings, flood cannot return because there is no sentient life left to take control of.

The rings were created by the forerunners as a last ditch effert to destroy the entire galaxy of sentient life so the flood would no continue on taking over the galaxy.
