I love the art style and the music and its subtle nods to Metroid Prime.Halo meets Metroid is a magical combination.
I love the fact that there are now loadouts instead of being lumped with what the majority picked.
No armor lock lol.
I love a lot of the new armor and being able to make the visor red.My current favourite is Hazop.
I love the run button.
I love that Halo is still the best console FPS after all these years (in my opinion).
