You have to get certain achievements that unlock certain armor permutations.
No. If you want to bye helmets go to the armory.
No you cannot buy halo 3 helmets in the game... but you can buy nerdy plastic helmets at like Gamestop...
you have to unlock achievements
you must have several achievements from HALO 3 and HALO ODST. Along with certain achievements from HALO REACH. Then you will unlock the two helmets
There are no Halo 3 helmet unlocks on easy. You will either have to beat the whole campaign on normal to get the E.V.A helmet or Legendary to get some elite helmet. You can also unlock the helmets with a friend on Xbox LIVE if you are afraid that you cant do it by yourself.
Technically speaking, all the helmets in the armory are Spartan helmets. If you mean the specific helmet worn by Master Cheif in Halo 3, the MJOLNIR MK. VI, then that costs 300,000 credits.
To Get the E.O.D Helmet You Just Have To Beat Every Level on Legendary or To Get HayaBusa get all the skulls.
After Halo 3 there was halo wars, halo 3 ODST, and Halo reach. A new company (not Bungie) will be making a Halo 4 and rumor has it there will be a remake of Halo Combat Evolved.
get x box live and play for 3 months within that time youll get it check your helmets when you rank up
get a new halo 3 disc
Well there are a couple of ways to get the helmets: 1. Playing the campaign (depends on the difficulty) 2. Earning achievements 3. Getting a certain amount of gamer score 4. You can get Recon from Halo 3: ODST Hope that helps!!
No, It does not. Halo ODST is the story of a squad in New Mombasa before/during the events of Halo 3
