Games Halo 5: Guardians

[NO SPOILERS]
Hey everyone, what do I need to know, once you have played this, to stay up to date with playing Halo5?
I know I will probably need to read Halo: Escalations.
However, does Hunters in The Dark need to truly be read?
Is Halo: Broken Circle relevant? —i’m 50% done.
Halo: Last Light --100% done

I have read The Forerunner Saga (Cryptum, Primordium, and Silentium).

Thanks for any help. I fell behind before the game came out, my bad.

I take it Halo:Escalation issues 20-23 would show up in Halo5 ?

Well, maybe I should take this to another website to ask. Then again, perhaps all of you are just too busy playing the game to come on here to answer me, xD.

Honestly, so long as you’ve read the Forerunner trilogy (which you have), you’re golden. I just read Cryptum for the first time yesterday in preparation, and that by itself was enough to let me appreciate the gravity of what’s going on with the ending.
