i guess that's what determines if the skull is a Silver or Gold skull
You do not keep the skulls in Halo 2 they are a one level sort of thing.
There are no skulls in Halo Reach.
Search for Halo 2 skulls on www.youtube.com and there will be a selection of videos showing the wereabouts of the skulls or how to get them : )
you can get all of the skulls on multiplayer. =)
They are skulls. idiot.
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.
Sorry there arn't any, The only skulls are in "Halo 3" Which are used in "Halo 3 O.D.S.T."
You need to find the skulls on Normal, Heroic or Legendary modes, on Easy mode you won't be able to find them.
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
There is many silver skulls, look up a tutorial.
Find them your self
You click on the tab that says skulls and you click on the skull.
