As you know, the hud in ODST looks as if you have a helmet on.
Sgt. Johnson doesn't wear a helmet, so it'd be kind of peculiar to have the following HUD Effects
1.) HUD symbols shaped as if on Helmet, this happens in halo 3 as well
2.) HUD ''powering on'' when you respawn, as if it's some sort of mechanical visor. This happens in halo 3 as well
3.) VISR [Confirmed by BUNGIE that this remains a part of Johnson's arsenal, even though it doesn't make sense.]
The question becomes, will #1 and #2 be eliminated when playing as Sgt.Johnson, since he lacks a helmet? What about other characters that don't have helmets, will the hud change as them as well?
My answer is ''YES''. Why? Well, because Halo 3's engine allows for 2 seperate huds (Elites vs Spartans), one of them is swapped with the ODST hud in this game. The other hud (what used to be the elite hud) could become the ''I have no helmet'' HUD for characters like Sgt. Johnson. The HUD would instead look a lot of like Halo 1's HUD (Which is a great idea!)
What do you think? Plausible?
