So playing through campaign and first thing I noticed was the HUD display is the exact same as the Cheif’s visor (as in the outline) also when you look up you see his little sun protector thingy ma bob but anyways, me and a few other friends was talking and I said 'Wouldn’t it be really sweet if each helmet you unlock the HUD display is different, for example the Scout helmet wouldn’t it be pretty cool if the display was say Red or black? (maybe if you change the Visor color the HUD changes even though the Cheif’s visor is like a bronzey orange but still blue)also like the outline of your visor is your HUD say Orbital has like a faint skull mark but obviously not interfering with game play, sorry if it is not clear but just a suggestion.
