If i am correct then it is the same as the skulls being off.
there is extra speech, but u dont need the skulls turned on 2 get it.
To Get the E.O.D Helmet You Just Have To Beat Every Level on Legendary or To Get HayaBusa get all the skulls.
when get achievements (like beating the game on Legendary or finding all the skulls) you can unlock some of the armor.
you can get all of the skulls on multiplayer. =)
if you want to know where the skulls are all you have to do is go to youtube and put in "halo 3 odst mythic skulls" and it will show you how to get to them
If you want all the achievements, then play Legendary. If you just want the "Complete Mission #" achievements and the skulls, play on anything other than Easy.
ok, go to youtube and type in "how to find all halo 3 skulls" then watch the video and get the skulls. yes, its that simple.
you only get the recon armour if you beat all the windmaster achivments, and find all the mythic skulls. (you have to prove to bungi that you did this.
Find them your self
The skulls are hidden all over the map. To get them all you have to do is find them and pick them up.
