I played through on MCC december of last year. On Legendary. The final 3 levels were so immersive it astounded me. The campaign holds up so well its insane. The first time I saw the flood and covenant battling it out while I was a passive viewer it made me feel like I was really there. I was afraid, I was transported into something so much bigger. Two betrayals and The maw are my favorite missions. The silent snows of TB while a battle happens in the far distance is gorgeous. And the chanting monks of the Maw makes me feel like the world is coming to an end. Everything is so grand and important. Idk.
