Yes, you must be on Legendary. What I like to do is create a separate profile with which to get each skull. Go through the level until you get to the checkpoint right before the skull, save, and quit. Never use that profile for campaign again. Now, all you have to do is go to that profile, resume campaign, pick up the skull, and quit the game. Once you pick up a skull, it is active for ALL PROFILES, and ONLY IN CAMPAIGN. I recommend switching to your main profile after picking up the skull. The only way to turn the skull off is to turn off your xbox.
No, it's legendary only sorry
No you only have to be on normal.
If i am correct then it is the same as the skulls being off.
you can do it on normal, heroic, and legendary, but not easy
You can do it on Normal, Heroic and Legendary. You can't do it on Easy.
You need to find the skulls on Normal, Heroic or Legendary modes, on Easy mode you won't be able to find them.
To Get the E.O.D Helmet You Just Have To Beat Every Level on Legendary or To Get HayaBusa get all the skulls.
Different skulls are available on each level. You must be playing on Legendary difficulty for them to appear.
Sorry there arn't any, The only skulls are in "Halo 3" Which are used in "Halo 3 O.D.S.T."
when get achievements (like beating the game on Legendary or finding all the skulls) you can unlock some of the armor.
Normal, heroic, or legendary. I found a two skulls on easy, but I didn't get an achievement.
They are skulls. idiot.
you can get all of the skulls on multiplayer. =)
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.
