DEV feedback:
Killcam is useless and has low integrity for showing a true POV from your opponent. Just keep the classic deathcam where one could immediately look out for teammates while waiting upon respawn.
Controller settings should ALWAYS be now fully customizable and the game should do away with all other schemes besides maybe a recommended default layout. At least give the option to customize controller settings in addition!
Consider that campaign and MP DO NOT require the same dynamics. Halo would stand out most significantly if the DEVS made campaign uniquely different than MP. The campaign shouldn't be limited to the same kind of playability to that of MP and vice versa. In other words, consider being open to both parts of the game to being completely different so as NOT to limit quality and innovation, but rather enriching both elements of the game independently.
