Yes, you do. Otherwise, you cannot use the skull as an attachment or extra.
no.... im a holo freak.... in fact to get skulls in halo you find them when you play each level... so each level has a skull hidden in it... you just have to look for it...
You have to do the leval where you stick your dick in tartares's ass! the skull is actually his boner!
i heard you have to fall on a platform in the halo level while the tiles fall
On campaign on halo 3 (difficulty normal or above) by the river on the first level jutting out on a rock theres a skull.
Depends on what level You beat it on.
No
The first skull on halo 3 is a silver skull. Silver skulls do not award any achievements.
It is some were in the second level ,but if you what to know the exact spot look on youtube.
All Skulls Can Be Found On Normal Or Higher
you have to beat it on all difficulty levels and obtain every hidden skull in the game.
Just follow what Cortona saids.
After finding a halo 3 skull, simply pick it up as you would any other weapon.
