why cant i keep my halo 3 skulls?

[Tired of Spam]

I just started collecting the skulls to unlock some hyabusa armor today and i was wandering how i save the skulls once i grab them. On Serria117 or somethin like that i grabbed the first skull and i went as far as the two pelicans crashing while holding it and when i saved and quit i cant find my achievment or a skull collection. It never even said i got one, how do i do it?

hard drve in all the way with ur account. thats interesting cuz mine didnt do that i grabbed it didnt say anything dropped it and went on til the lvl was done. u gotta b playing on anything but easy though. so was it that.

once you get the skull they disappear you cant get them again

2 things...
you should be unlocking the achievement as soon as you pick it up, make sure your logged in

and HALO 3 sucks, get a real game like Gears of war 2 or Call of duty 4

EDIT: one of the skulls on SIERRA 117 IS NOT an achievement skull, you may have just picked up the wrong skull, check youtube

that is a glitch i have never heard of before, make sure your on the same account that you claimed the skull on, and if not try it again and see if the skull is there. if not i don't know what to tell ya...

I havent the slightest idea as to what you are asking
but I asked my boyfriend and he says the skulls save automatically
so....
I hope that helps
