ok ive heard alot about the skulls but what exactly is up with them??? ive heard someting about a gate, and that you have to get them in a certain order? is there actually a gate or a prize for finding them all ina certain order? or is it B$

No, you don't get anything for getting them in a certain order. If you're looking for cheat skulls, just do a google search and you should be able to find a website that has them all listed. There's at least one in every single player level.

well i studied it a ton, you're right. i got a lot of help from www.highimpacthalo.org otherwise i'd still be trying to figure it out

HIH...WOW! I havent been to that website in like a year.
I remember all the glitches and tricks they had on there.
Anyshit, I had alot of fun with the sputnik skull...(isnt that the one that mades you grenade jump high as hell?)
