I think they should bring back the specters,smgs,dual wielding,hawks,grizzleys,brute shot,sword from halo 3,covenant sniper,experience points. I think they should take out beam rifle, armor abilities. They should add some new vehicles like the one from halo legends the package,a map in space were you can use longswords, sabers,pelicans,seraphs,phantoms, etc. also they should make an emp grenade, make the bubble shield a grenade.
