So aside from the graphics of the game, I will say 343i has almost nailed everything else. They have found the perfect blend of old and new with elements from h3, reach, and even h5. Now I will say there are a few design choices for the banished that were questionable, like the phantom, some of their armor, and the new brute launcher. I’d definitely like a little reform, just slight adjustments. Other then that this screams and bleeds Halo and I just wanted to let 343i know that everyone enjoyed a lot of the elements and ik right now the community is harping on graphics for good reason, but 343i great job honestly 
Also why the brutes don’t have hair again?
