halo 3 skull help?

[Fredbingerman]

ok when i was playin the last mission, i found the skull and when i picked it up it said "mythic". Later i went to teh first mission (serrra 117) and i found a second skull. But when i picked it up hothing happend, i had it in my had but there was no words. (also on both of these i was playing on heroic and i had beten teh game) also how do u view the skulls you have already picked up because i now that once u pick them up u can activate them any time.

You have to start at the beginning of the mission to get credit. You can't start at the level where the skull is located.

in the pregame lobby before you start campaign hit x i believe and it should show you skulls as well as the ability to turn points on and off.
