You have to be on normal and hold down RB to pick them up.
Just hold the skull until you get an anchevment for it, then save and quit.
Im pretty sure you just tap RB or hold it down
It's easy.... Just walk over to it, and hold right bumper (RB). Once you've picked it up, you don't need to hold it for any longer so drop it.
You can carry it around all the time if you want, but you don't need to. once you got the hold of one, you can activate it by pressing x on the campaign page and the ones that you've found will be glowing. press on them and they will low brighter to show that they are in effect.
When you get the skull on any level (to pick it up get close to it and hold X thats if u have it for xbox) a flash of white light will appear on you and dont panick its normal.If you search up what the skulls do u will be able to do that.to use it on another level save and quit then u can use it on that level.Once u turn off whatever u have the skull abilites will disappear so dont panick its normal.
It can hold certain ones.
When you are behind an enemy, HOLD your melee button for the assassination (normal ones are called beat downs,btw)
What do you think? 'HORNS' holding up her 'HALO'.
You can't only on halo 2 and 3 you can

Go near a mongoose and hold RB when it says "hold RB to drive mongoose". This is the same way to get in any vehicle in Halo 3.
