I am disappointed with the lack of acknowledgement of 20+ years of source material ignored. Silver team is literally a reskinned blue team. Miranda keyes is a lieutenant in the games not a doctor. All humans can use forerunner tech due to them being the inheritors of the mantle of responsibility. The first person view of chiefs visor depicts shields as the health bar. The guns don't make the right noise. Chief doesn't find out that halo is a weapon till after 343 guilty spark tricks him into almost activating it. Chief has a personality in the games. Cortana isnt a microscopic chip in chiefs brain she's stored in a drive that is attached to the back of his brain and the mjolnir armor. Cortana isnt a control system to keep master chief in check.
